My baby turned 1 month old yesterday. He's normally pretty chill while nursing. Just would lay there. Past couple days though he's been very squirmy. He'll nuzzle and mouth at the nipple, make little moaning noises, wiggle, need my breast with his hands like a cat, punch, sometimes rip off his latch and scream, act lost likd he can't find the nipple that he just pulled off from....

What could be wrong? He gets gassy but never acted like this. Anyone else experience this?
