Ep. 93 – The Fourth Trimester: Medications, Beauty Products & Breastfeeding After Birth

The weeks after delivery (often called the fourth trimester) can raise just as many questions as pregnancy itself. From pain management and supplements to beauty treatments and mental health medications, many parents are unsure how different exposures may affect breastfeeding.

In this episode of The MotherToBaby Podcast, host Chris Stallman, MS, CGC, is joined by Kirstie Perrotta, MPH, and Angela Messer, MS, Teratogen Information Specialists from MotherToBaby California, to discuss some of the most common postpartum questions they receive from parents and healthcare providers.

Together, they explain how exposure information is evaluated during breastfeeding and how factors like dose, timing, and route of exposure influence what may reach breast milk.

  • What the fourth trimester is and why exposure questions continue after delivery
  • Common postpartum concerns, including pain medications, stool softeners, and laxatives
  • How prescription pain medications, including opioids, are evaluated during breastfeeding
  • Why route of exposure matters when considering topical products
  • What to know about hair dye, Botox, manicures, facials, and salon treatments
