My baby boy is 5 weeks and everytime he sleeps he strains/pushes/grunts in his sleep. Sometimes its so bad it even wakes him up, I havent seen him sleep soundly since he was 2 weeks. He clearly looks like he's in pain😔. Anyone else's baby experience this if so what helped? I've tried gripe water and it does nothing for him. He's also taking zantac twice a day but that doesnt seem to help either
