Aunt Nan says, “Breastfeeding will make your boobs sag.”

Breastfeeding doesn’t cause breasts to sag – pregnancy does! During pregnancy, hormones cause the ligaments in the woman’s pelvis to relax to allow it to expand during birth. The same hormones also relax the Cooper’s Ligaments, which attach the breasts to the chest wall.

Ask around – you probably know someone who fed their baby formula and complains about having saggy boobs, and you probably know someone else who breastfed their baby and their breasts don’t look much different than before having children.
