"He'll look at our daughter and be like, 'Can you believe your body is able to feed our baby?' " she said.
"Sometimes, I think — especially as women with this pressure to bounce back after baby — you have to keep in mind that when you're breastfeeding, you need to, as my husband says, 'eat to win,' and to feed yourself so you can also properly nourish your baby. Because for a lot of people, what you eat and how you treat your body also hugely impacts your milk supply," she added.
