My bby girl is 10 days old. She was doing the poopy fine. Now she's been only been doing it 1 time a day. She does pass gas. And I've given her water, it worked the first time. Now she hasn't gone and I think I've seen her struggling. I was breastfeeding but i wasn't producing enough so I gave her enfamil formula. Anything else I can do, i would stick to breastfeeding but I got a c-section and I'm taking medication..I know it's the milk and the transition but if I change her milk again won't get tummy become more upset...
