Inclusion for All
MotherToBaby welcomes all individuals and families at all stages of their pregnancy and lactation journey and recognizes that not all people identify as “men” or “women.” We strive to use gender-neutral language when talking about pregnancy and lactation. By using inclusive and non-gendered terminology, we strive to enable all families to be empowered to reach their personal and familial pregnancy and lactation goals. While our name still contains a reference to “mothers”, we have updated our website and resources to use more inclusive terms where possible and where doing so allows the overall message to remain clear to the general population. We welcome feedback on any of the terms used and acknowledge that our understanding of these terms will evolve over time and is always better informed by open dialogue.
