Zr is 4 weeks old. She was very gassy so we had to stop breast feeding for 2days and give her formula while I pumped and went to a gluten free diet. Now when I breast feed her she eats for 5 minutes and falls asleep. No matter what I do (change her, tickle, undress her) she will give me another minute until she passes out again. That would be great but her hunger takes over 20 minutes later and we go through the same routine again. When I give her pumped breast milk she only will sleep for 1-2 hours before she's up and hungry again. When I was giving her formula she was sleeping upwards of 3 hours. Would I dry out if I supplement formula at night even if I continue to pump? Will the switch upset her stomach? Would it diminish my supply if I pump? Any tips would help.
