Baby girl is a little bit over a week old. The first few days I only breastfed but since she wasn’t having bowel movements the pediatrician told me to give her formula after every feeding, it worked, she pooped. Now it feels like my breast milk isn’t filling enough for her though! She’s constantly trying to feed and to suck on whatever her little mouth can reach. When I feed her formula she seems way more content and she lasts longer before she’s hungry again. I want to exclusively breast feed but I don’t know if I’m producing enough milk to do away with the formula. Thoughts?
