Find out why your breasts continue to grow in the third trimester and what you can expect post-delivery.
Are you surprised at how big your breasts have grown? Breasts grow even larger during the 3rd trimester. You may even find that when you sit down your breasts rest on your belly. It's not a wonderful feeling, but at least it's for a good cause: Your breasts are preparing to produce milk that can later nourish your baby.
Although your belly will become smaller right after your baby comes out, your breasts will not. In fact 24 hours to 48 hours after delivery, they will grow even larger as they fill with milk. (It's a process also known as "letting down" or "having your milk come in.") Nursing or expressing the milk reduces their size until the next breastfeeding session, when they fill up with milk again. Your breasts will return to their prepregnancy size after you wean your baby.
