My baby had colic due to an intolerance to cows milk protein
We just did half a pipette of infacol before every feed, literally after a day made a massive difference. We never finished a tub( biggest bottle they do) just after a few weeks I stopped one day to see and he was fine
Yep. CMPA was the cause for us. Once we went dairy free the colic resolved.
We thought our little one was colic but in the end it was because he had really bad tongue tie and had to get snipped
This is tough. I would say try to keep burping baby until nice big burps and massage tummy. you can use YouTube for guidelines on how to baby massage colic baby.
