Need some help. Baby just turned 2 weeks 2 days ago. She was great the first 10 days. Never cried or anything. I'm exclusively breastfeeding. Starting Sunday anytime I feed her she arches her Bach afterwards and gets very fussy fir a long time afterwards. She wont cry but she will grunt a lot and let out some screams. Last night she was up from 3:30am-9am. I've modified what I've been eating but it doesnt seem to help. I've tried gas drops and gripe water too but nothing. Anyone else going through this? Will it get better?? I'm getting anxiety any time I have to feed her because I know what will happen afterwards. I've also been keeping her upright for 20 min after every feeding.
