3. You Might Go Up a Bra Size (or Two)
After you give birth, your body produces less estrogen and progesterone, but more prolactin, a milk-producing hormone. This change causes your boobs to grow even more than they did when you were pregnant and feel super tender. (Don’t worry, they’ll go back to their old size once you’re done nursing.)
4. But You Might Lose Your Pregnancy Weight Faster
Here's an added bonus: Breastfeeding burns 300 to 500 calories a day, meaning a lot of women see increased weight loss during this time. Of course this varies from person to person, but unless you're overcompensating by consuming extra food, you'll probably notice some of the baby weight falling off even if you aren't hitting the gym on the regular. (And who is, post-baby, to be honest?)
