I bottle feed expressed milk to my 3 month old. She used to take 4 ounces 5x/ day, but now she'll only want about 2-3 ounces. It's a struggle to feed her because she keeps turning her head away. I basically force feed her now. The Dr said she seems healthy and doesn't see signs of reflux. I'm worried because she already eats on the low side. Anyone have experience with their infant suddenly being uninterested in eating? Any tips?
