I have no appetite since giving birth. I had a terrible appetite before getting pregnant and I I just assumed it was because I was a smoker. Well, I haven’t smoked and I feel like my appetite it back to where it was. I’m happy I’ve lost a lot of my baby weight but I don’t want to be as skinny as I was before and healthy for little girl since I’m giving her breastmilk via bottle. She latches well but gets frustrated and ends up pulling away frustrated after a couple minutes. Any tips to help with appetite?
