Sorry, my little boy didn't have gas. He never cried unless he was hungry. Here is a bump for you.
I changed the formula, I did nurse yet I wasn't making enough milk. The formula she was on, made her gassy and she had grown man farts! When I changed to gentlease, all was well and she was much calmer along with less gas.
Check if its that, if not maybe upset tummy.
It could be the formula, it could be that he needs gas drops or that he's constipated.
