As we continue to celebrate International Women's Month this March, Dr. Sonia Gayete-Lafuente talks about a powerful and often overlooked aspect of motherhood: lactation without pregnancy. 

For many women and families, the ability to breastfeed represents far more than nutrition. It’s about bonding, connection, and participation in a deeply meaningful part of early parenthood. The good news? Even if you didn’t carry the pregnancy, breastfeeding may still be possible.
