Boobs after breastfeeding
The shape and size of your breasts change both before and after breastfeeding. To prepare for nursing, breast tissue and milk-producing glands enlarge and become fuller. Once you’ve finished breastfeeding, they shrink back down to their previous size. You may then notice that your breasts are softer and less full than when you were nursing, resulting in a droopy appearance.
The extent to which your breasts regain their pre-pregnancy size/shape depends on many factors, including age, weight gain during pregnancy, and even genetics. Also, if you’ve ever been a smoker, your skin may have less elasticity and therefore be prone to sagging.
Nipples after breastfeeding
During pregnancy, high levels of estrogen and progesterone affect the nipple area as well. Your nipples might increase in size, and the surrounding areolas can darken and develop striae, or lines.
Constant breastfeeding could also cause pain and soreness in your nipples. It’s unknown whether or not they’ll eventually return to their original shape and/or color.
Does breastfeeding lead to sagging?
Contrary to popular belief, studies show that breastfeeding is not directly related to droopy boobs. When you’re pregnant, the connective tissues in your breasts (known as Cooper’s ligaments) become stretched out. This means you may experience post-baby sagging even if you choose not to nurse your newborn.
