Breastfeeding and Breast Size
Visitor Question: Do your breasts get smaller after milk has dried up from breastfeeding?
Breastfeeding Magazine Response
The answer is different for every mom. Normally they will become smaller than when you are pregnant or breastfeeding. However, they'll probably just return to their pre-pregnancy size.
It also will depend on your overall weight.
If you still weigh more than you did before your pregnancy, your breasts may also be bigger. If you weigh less than you did, they may, in fact, be smaller.
