Have you ever had a pregnant friend tell you, “it is OK to have just one glass of wine now and then, that’s what my doctor said,” or “my mother drank beer when she was pregnant with me, and I turned out fine.” As a Teratogen Counselor (a birth defects expert), I hear these statements more than you would imagine. You may think it is common knowledge that there is no safe level of alcohol use during pregnancy, and that any use of alcohol while pregnant has the potential to harm the baby. Yet that message is not getting out there to everyone. Studies have long shown that heavy use of alcohol during pregnancy can cause Fetal Alcohol Syndrome, while more recent studies suggest that moderate use (and possibly even light use) can cause long term developmental problems in an exposed child. In fact, Fetal Alcohol Spectrum Disorder is thought to be the leading cause of developmental delays in children. Despite this, studies also show that 1 in 10 to 1 in 13 women continue light drinking of alcohol, even after they know they are pregnant. So I started thinking… Why do some woman continue to drink alcohol during pregnancy?

1. You Didn’t Know You Were Pregnant
Most women find out they’re pregnant when they are 4-6 weeks along – and many may not recognize the signs of pregnancy for quite a few months. So unless you are planning your pregnancy (50% of all pregnancies today are unplanned!), you may indulge in alcoholic beverages before you even know you are pregnant. Thankfully, the majority of women will stop using alcohol once they find out they are pregnant. But unfortunately, the damage could already be done. Harmful exposures (like alcohol) during those first critical weeks of pregnancy have the greatest risk of causing major birth defects. This is why experts at the Centers for Disease Control and Prevention (CDC) recommend that women avoid alcohol not only if they are pregnant or trying to become pregnant, but also if they are sexually active and not using an effective method of birth control.

2. Mixed Messages
It’s not uncommon for pregnant women to receive mixed messages from people they trust about how safe alcohol may be in pregnancy. Even her own doctor may tell her that an occasional glass of alcohol won’t harm her baby. There’s a lot of misinformation out there, even among healthcare providers! It’s important for you and your healthcare provider to keep in mind that the experts at the American College of Obstetricians and Gynecologists and the American Academy of Pediatrics (among many others) advise that women avoid alcohol entirely while pregnant, because no amount of alcohol – even light-to-moderate amounts – can be considered safe for a developing baby.

3. It’s A Social Thing
Social pressure from family or friends can be strong. If a woman is used to going out on weekends with her friends and everyone has a glass of wine, she may feel that she needs to drink too, just to fit in. Plus many women feel that the risk of having just a little alcohol during pregnancy is low. These same woman may be doing everything else that they can to remove all other risks to their pregnancy, but they still continue to use alcohol. At MotherToBaby, we understand that the use of alcohol during pregnancy may have perceived benefits to a woman. But we also know that alcohol provides ZERO benefit for a developing baby, and, in fact, can only harm the baby. And because the exact amount of alcohol that could harm a baby is unknown at this point (and does vary woman-to-woman and even pregnancy-to-pregnancy), our philosophy is: WHY TAKE THE RISK?

4. It Helps Me Relax, De-Stress, and Just Deal with Everyday Life
Recently a 35 year old caller told me that she continued to enjoy a half glass of wine every weekend as a treat to herself. “Susan” (not her real name) knew that she was not supposed to drink alcohol, and she even said she got a lot of negative feedback from family and friends, yet she continued to drink throughout her pregnancy. Without realizing it, Susan and other women may be using alcohol to help deal with other unrecognized issues in their lives, such as depression and anxiety, high levels of stress, or little outside support for the pregnancy. At MotherToBaby, it is our job to help women understand how fragile and vulnerable a pregnancy can be to certain exposures; alcohol is one of the dangerous ones. While it may seem a hardship to give up alcohol entirely while pregnant, think about it this way: Pregnancy is only 9 months long (less if you base it on when a woman learns she is pregnant). If a woman is strong enough to survive childbirth, courageous enough to take on the toughest job on earth (parenthood), and resilient enough to survive that job, then abstaining from alcohol for the duration of a pregnancy is nothing. And if it means giving your baby a chance at the best possible start in life, then not drinking alcohol while pregnant is everything.

What Do We Know? There is not a known safe level of alcohol use during pregnancy.
We have known about Fetal Alcohol Syndrome for over 40 years now. Dr. Kenneth Jones, the doctor who first named Fetal Alcohol Syndrome in 1973 states: “When talking about the prenatal effects of alcohol, we usually think exclusively about the dose, the strength, and the timing of alcohol exposure. However, perhaps even more important are factors involving the mother – her genetic background and nutritional status to name just two. Without knowing those genetic and nutritional factors that are critically involved with the way a woman metabolizes alcohol, it is not possible to make any generalizations about a “safe” amount of alcohol during pregnancy.” Studies have shown moderate use, and possibly even light use, of alcohol during pregnancy can cause long term developmental problems in the exposed children. In fact, Fetal Alcohol Spectrum Disorder is thought to be the leading cause of developmental delays in children. Scientists are continuing to study how and why alcohol affects the developing baby, and in future years we will know more about this. But for now we do know there are always risks with drinking alcohol during pregnancy.

**This information was current as of the time the blog was published. However, information is constantly changing. Please visit Zika Central for the latest information.**

As a teratology information specialist, I counsel women and their families on medications, chemicals, herbal remedies, and illnesses that could harm developing babies. So as the Zika Virus, a viral infection that can cause severe birth defects including microcephaly (a condition where a baby’s head is much smaller than expected, and may indicate a baby’s brain has not developed properly during pregnancy), spread from the Polynesian Islands, to South America, to the Caribbean, I made sure to educate myself on everything we know about the virus, reading article after article and keeping up to date on the Centers for Disease Control and Prevention (CDC’s) recommendations to avoid infection, knowing that eventually I would need this information to counsel a pregnant woman or her family. I never imagined I would use this information to try to prevent becoming infected myself, and that I would fail.

One week in February I opened an email from my in-laws with the subject “30th Birthday Plan.” My husband’s 30th was a few weeks away, and I was excited to see what they had planned. As I read the email detailing a week-long sailing trip in the Caribbean I felt blessed, and honestly a little scared. I rushed to the CDC’s page on Zika to look up whether the islands we were visiting had outbreaks. Sure enough-16 Caribbean islands, including the two we were visiting, had Zika outbreaks. At first I didn’t want to go, which set off an intense inner debate racked with guilt. “How could I say no to a surprise trip for my husband, especially one planned and paid for by my in-laws?” I thought, and in the next second, “But what if I get Zika? I work with pregnant women, I can’t expose them!” Finally, my Dad stepped in. “You’re too adventurous to let Zika scare you away from a vacation.” he said. “Fine,” I thought, “I’ll go, but I’m going to be careful.”

I was careful. Despite the gentle teasing from my in-laws, I insisted on sleeping indoors with the windows closed, even though it was more comfortable outside. I wore bug spray with 30% DEET when I thought mosquitos would be out. I got three or so bites at dinner one night, and three more at the end of our trip. As we headed home I mentally patted myself on the back; “Only six bites,” I thought, “pretty sure I didn’t get Zika!” I was so sure that three days after our trip when I developed a head-to-toe rash I was certain it was an allergic reaction, but after three doses of Benadryl did nothing, I googled Zika-related rashes. Dead ringer. Symptoms of the Zika Virus include rash, joint and muscle pain, red eye, fever, and headache, and boy did I have them. I rushed in to see an infectious disease doctor, who came to the same conclusion. “My money’s on Zika,” he said. Suddenly everyone wanted a piece of me; my blood was sent to the county board of health, Emory’s lab, and a lab in Washington for testing.

A call from the county board of health confirmed what my aching joints hinted at: I tested positive. My first thought was to thank my lucky stars that I have access to safe, reliable birth control. My second was to start worrying about those around me. I had brunch with a pregnant friend before I had symptoms-could I have given her Zika? Thankfully, the answer is no (more on that below)! I was amazed at how a short vacation and six bites could give me Zika. I thought about all the people going to the Caribbean for vacation. How many of them are pregnant or could become pregnant while traveling? Would they wear bug spray? Would they recognize the symptoms? How many are men who could get Zika and then unknowingly transmit it to their sexual partner? How many people are walking around not knowing they were infected? I called my friend and begged her to wear insect repellant for the rest of her pregnancy.

As of July 27, 2016, 1.658 cases of Zika, including 433 pregnant women have been confirmed in the continental United States; 4 cases of local transmission have been reported in Miami-Dade and Broward counties in Florida. There are likely far more cases since most people don’t have symptoms, so never get tested. Zika is mostly spread through mosquito bites, but can also be spread through sex, blood transfusions, or from a mother to baby during pregnancy. We don’t know how long the incubation period (the time between when you get infected and when you see symptoms) is, but it is likely a few days to weeks. For most people the virus stays in the blood for about a week, but some people still have the virus in their bodies for as long as two months. Currently, the only Zika outbreak in the continental United States is in a small area of Dade County, Florida, however,, the mosquitoes that can carry Zika are found in some areas of the US, making a Zika outbreak in the U.S. very possible. You can follow these steps to protect yourself:

1. If you are pregnant or could be pregnant (planning a pregnancy or not using birth control), don’t travel to a country with an active Zika outbreak. You can find a list of current outbreaks here.

2. If your partner has traveled to a country with an active Zika outbreak and you are pregnant, use condoms correctly every time you have sex for the rest of your pregnancy. Why, you might ask? Because Zika can stay in semen longer than in blood, but we don’t know exactly how long it stays there. To be as safe as possible, the CDC recommends using condoms for 6 months.

3. If your partner has traveled to a country with an active Zika outbreak and has symptoms of Zika (rash, fever, headache, joint pain, and conjunctivitis) use condoms correctly whenever you have sex and avoid pregnancy for at least six months. If he does not have symptoms, use condoms and avoid pregnancy for at least two months.

4. If you have traveled to a country with an active Zika outbreak and you are not pregnant, avoid pregnancy for at least two months. The Zika virus can also be transmitted from a woman to her sexual partner. Because of this, use condoms and/or a dental dam when you have sex for two months. Do not share sex toys.

5. If you are currently pregnant, avoid mosquito bites as much as possible by wearing bug spray outdoors (bug spray with at least 30% DEET is preferable; for information on the safety of DEET during pregnancy, see here), wearing long-sleeved shirts and pants, closing windows or using windows with screens, and removing any standing water from around your house. Two things to remember: the mosquitos that spread Zika are daytime biters and like to be indoors, and they can breed in pools as small as a bottle-cap.

So…you were really good during your entire pregnancy, giving up every drop of alcohol, quitting smoking tobacco, and, of course, avoiding any drug like marijuana. You were concerned about the development of your baby, and doing everything you could to make a healthy outcome more likely. Good job! But now here you are….you’ve had your baby, you’re giving breastfeeding your best shot…do you still need to be so careful? If you’re wondering this, you’re not alone. It is a top question I get as a health care provider and one of the top questions we get from moms through MotherToBaby’s text information line. I’m a mom myself and after I had my boys, I asked the same things, like “would having a glass of wine when I’m on a date with my husband be the end of the world if I’m breastfeeding?”

Alas, many years later (and many published studies later), I have answers for you.

Let’s start with the facts about breastfeeding. Breastfeeding is good for you and the baby, and you should continue nursing for at least 6 months… and better-yet, a year.

I think of alcohol and tobacco as ‘recreational drugs’ because there is not any medical reason to use them. And while medical use of marijuana is becoming more widespread, for most of us the use of marijuana is not medically necessary. We don’t want rules surrounding the use of alcohol, tobacco, and marijuana to be unnecessarily strict so that they discourage nursing for the optimal amount of time. But we also want nursing moms to know that each of these drugs are passed to breast milk. Fortunately, there are often ways that we can limit the amount that baby gets.

Let’s take a closer look at each one…

Alcohol—alcohol of all kinds (wine, beer, liquor) passes into your milk. Babies don’t like the taste of it, and, if it happens often enough, babies may show developmental delays from exposures to alcohol through breast milk. Fortunately, waiting 2-3 hours after drinking a single alcoholic beverage results in lower amounts in milk. If you have two drinks, wait 4-6 hours…you get the idea. You can pump for comfort and to maintain your milk supply, but be sure to throw away the milk since it likely has alcohol in it. Chronic or heavy users of alcohol probably should not breastfeed.

Tobacco—you know that it is best for your health and that of your baby to avoid smoking tobacco, but if you cannot resist, keep the number of cigarettes as low as possible (preferably less than ½ pack per day) and never smoke around your baby. Nicotine gets into your milk, so try to wait several hours after you smoke before nursing your baby. Second hand smoke increases your baby’s risk for ear and respiratory infections, asthma, and even sudden infant death syndrome. The immunoglobulins in your milk help to lessen those risks, which is why most experts still recommend breastfeeding even if a woman is smoking small amounts of tobacco.

Marijuana – THC, the active ingredient in marijuana, passes into breast milk. Marijuana production is not very well regulated, so there may be other dangerous contaminants. There are not many studies regarding use of marijuana and breastfeeding, but there are concerns that exposure to THC via milk might affect baby’s development. It can also reduce your milk supply. Until more is known, it is recommended that marijuana be avoided in breastfeeding women, and that an effort also be made not to expose the infant to second hand marijuana smoke. If you happen to use marijuana, waiting 1-2 days before resuming nursing will help reduce the amount in milk. Pump and throw away milk in the meantime for comfort and to maintain your milk supply.

Bottom line, by breastfeeding, you’re already taking the first step in providing continued important nutrition for your baby. Way to go! Taking steps to make sure your breastmilk stays as healthy as possible for the entire time you breastfeed will be well worth the effort. Stay strong, live well.

**This information was current as of the time the blog was published. However, information is constantly changing. Please visit Zika Central for the latest information.**

When it comes to pregnancy, so much of the attention is focused on the woman: her nutrition, her health, her behavior and just about her whole world comes under scrutiny in order to promote a healthy pregnancy; but what about the man? His nutrition, health, and behavior hardly comes under that same intense scrutiny…until now. Enter Zika virus. A man who has traveled to a Zika-affected area and has a wife/girlfriend who is pregnant must play an active role in protecting his partner and baby from possible Zika infection. Even if his partner is not currently pregnant, a man must be aware of his role when it comes to preventing the spread of the Zika virus. Father’s Day starts well before you actually become one, men….here’s why:

This illness, which is spread by the bite of a mosquito, took the world by surprise last fall when an unusually high number of babies, particularly in Brazil, were born with small heads and brains, a birth defect called microcephaly. Zika is a mild illness and typical symptoms include fever, skin rashes, muscle and joint pain, headache and conjunctivitis or red eyes. These symptoms normally last for 2-7 days. Some adults do not even know that they are infected because they have no symptoms while others will recover with rest, fluids and taking over-the counter medications to control symptoms. While Zika is a mild illness for many adults, if a pregnant woman becomes infected she can pass the infection to her child and, as a result, increase the chance that her child may be born with microcephaly and other abnormalities. To complicate matters more, it became clear that Zika can be transmitted by a man to a woman through sex or intercourse. The virus can be spread before symptoms begin and after symptoms end. Also Zika virus can remain in the blood of an individual for a week (or sometimes longer), but in regards to men Zika can remain in semen even longer than in the blood. Since we still don’t know how long Zika can remain in the semen, a man has to be more proactive than reactive when it comes to protecting his partner and future baby.

And ladies, our men, especially fathers-to-be, are thinking about Zika and are making some life changing decisions to protect the welfare of their families. Take, for example, cyclist Tejay van Garderen (27 years old) who is considered a medal contender for this year’s summer Olympic Games in Rio de Janeiro, Brazil. He has decided to withdraw from consideration to be a part of the US Olympic team because his wife Jessica is pregnant and he doesn’t want to put her or the well-being of his unborn child at risk by possibly contracting Zika and passing the infection on to them. “I don’t want to take any chances. If anything were to happen, I couldn’t live with myself.” When you consider that Tejay will now have to wait 4 more years to fulfill his Olympic dreams and put all that training on hold for his wife and child, that is chivalry at its finest. (All I can hear is the song “When a Man Loves a Woman” playing in my mind right now!)

So what is a man to do?

If you have a pregnant partner and you have traveled or lived in a Zika-affected area:

The most conservative approach is to not have sex during the entire pregnancy. Although the thought of not having sex for several months might seem like the end of the world for some, the health and welfare of your child is well worth the sacrifice.

However, every couple has to do what will work for them, so if abstaining from sex is not possible then it is important to use a condom correctly and consistently while having sex for the entire time of intercourse. Condoms should be used regardless of whether you are having vaginal, anal or oral (mouth to penis) sex, even if you do not have symptoms. Remember: since Zika virus is found in semen, the idea is to make sure your partner has no contact with semen. Think, knight in shining latex armor, right? Yet another chance for chivalry, guys.

If your partner is not currently pregnant:

If you and your partner are planning or actively trying to get pregnant but you’ve recently traveled to or lived in a Zika-affected area, experts advise you to hold off on getting pregnant. The length of time you delay would depend on whether you’ve had symptoms of Zika infection: delay 6 months men, if you have had symptoms, or 8 weeks if your wife or girlfriend had symptoms.. Avoid sex or be sure to use condoms every time , as mentioned before, during this period. If neither one of you have experienced symptoms than it is advised that you wait 8 weeks before trying.

Even if you are not planning a pregnancy, it is advisable to wear condoms every time you have sex because (well, you know) accidents have been known to happen! And you can even go a step further by not having sex for 8 weeks after you return from a Zika-affected area, if you have had no symptoms or for 6 months if you do.

Other Means of Prevention

Here in the United States, we do not yet have local cases of Zika – meaning that all reported cases in the US to date are from individuals who lived in or traveled to Zika-affected areas and have traveled back to the United States. While this is reassuring, we cannot be completely at ease and need to take the proper steps to prevent infection – especially since there is no vaccine or medicine to treat Zika. The use of insect repellents is an important tool in the prevention of Zika for everyone and especially those who are traveling back to the United States from Zika infected areas. The Centers for Disease Control and Prevention has some great info about Zika prevention: http://www.cdc.gov/zika/prevention/ 

If you are uncertain about your risk of infection, you should talk to your doctor sooner than later so that they can make a proper assessment of your level of risk. Zika testing is available for people who believe they have been exposed through sex and have symptoms; however, keep in mind that testing blood, semen or urine will not tell you the level of risk for passing the infection to someone during sex. In addition, because Zika can remain longer in semen than in blood, a man could get a negative blood or urine test but still have the Zika virus in their semen.

So men, prepare for your most chivalrous self. We need you in the fight against Zika! Your partner and future child will appreciate all you do to protect them.

It was the longest 3 minutes of her life. As she opened her eyes to glance at the test, her heart stopped. She couldn’t breathe. Frantically, she tore open the instructions that came with the test to confirm what she already knew. She was pregnant. She laid her head on the bathroom stall, tears threatening to fall. It was then that the bell rang, signaling the end of lunch. It was time to go to class. But all she could think was, “I’m only 16…”

May is National Teen Pregnancy Prevention Month, a good time to focus on the specific challenges a young, pregnant mother may face. Teen pregnancy raises a myriad of emotions and thoughts from the most practical of, “How am I going to finish school?” or “What will my parents think?” to the more profound, “Should I even keep it?” or “Could I have harmed the baby somehow?”

When trying to answer these questions, it should come as no surprise that teens are at a high risk for receiving misinformation from many sources, i.e. the internet, friends and media. As a certified genetic counselor at MotherToBaby, this concerns me greatly – for mom’s sake, as well as baby’s. When somehow that mom-to-be lands on the other end of my phone line, in my office or on the other end of an email, I am relieved. She’s found a trustworthy resource available for pregnant teens to help them answer these important, and potentially life-changing, questions.

MotherToBaby, a service of the nonprofit Organization of Teratology Information Specialists (OTIS), provides the most up-to-date, evidence-based information to mothers, healthcare professionals, and the general public about potentially harmful exposures, like alcohol, drugs and medications, during pregnancy and while breastfeeding. Each question that MotherToBaby receives is researched by a professional like me. From questions about bug repellant to illegal drug use, MotherToBaby has seen it all! So, what are some of the most common questions I get from young moms?

ALCOHOL. “Can I drink any alcohol at all during my pregnancy?” No amount of alcohol is safe during pregnancy. However, babies exposed to large amounts of alcohol at one time (i.e. binge drinking) and/or frequently throughout a pregnancy may be at risk for Fetal Alcohol Spectrum Disorder (FASD). Babies with FASD may have one or more of the following: birth defects, intellectual disabilities, learning disorders and/or behavioral problems.

CIGARETTES. “Why can’t I smoke cigarettes while I am pregnant?” There are over 4,000 chemicals and toxins in cigarette smoke. Several of these can cross the placenta and decrease the amount of oxygen and nutrients available to baby. Studies on heavy smoking (smoking 15 or more cigarettes per day) during pregnancy have shown an increased risk of oral clefts in newborns, as well as a higher chance for preterm delivery, low-birth weight or miscarriage. Long-term effects have included a higher risk for childhood asthma, bronchitis, and respiratory infections, as well as ADHD. It’s never too late to quit smoking – even reducing the number of cigarettes smoked per day will help!

MARIJUANA. “I’ve heard it is OK to smoke marijuana during pregnancy. Is this true?” There is conflicting information available about the effects of marijuana on a pregnancy. While some recent studies have shown that it has not been associated with an increased risk for birth defects or complications, there is not enough data available to say this with 100% confidence. Additionally, cognitive and behavioral problems have been seen more often in children whose mothers were “heavy” marijuana users (used marijuana one or more times per day). Again, the evidence is not conclusive and some studies report conflicting results. Plus, smoking is smoking, so heavy marijuana use during pregnancy can be associated with many of the same problems as heavy cigarette use.

METHAMPHETAMINES. “I’ve used methamphetamines in the past. Is this OK to use now and then while I am pregnant?” Methamphetamines (meth) should not be used at any point during pregnancy. Meth use has been associated with an increased risk of miscarriage or preterm delivery. Meth use later in pregnancy has also been associated with babies experiencing withdrawal symptoms after being born. Currently, there is not enough data to know whether meth use during pregnancy increases the risk of birth defects, although heavy use of meth during pregnancy may increase the risk for learning problems.

There’s no doubt the road ahead will be filled with many more questions for a young parent, but I’d like to think receiving a reliable personalized risk assessment about exposures during pregnancy and breastfeeding will be the start of an important support system she builds for herself.
