Could be worth a doctors visit. My little boy was exactly how you describe, and at 3 months, we were told he has a cow's milk protein allergy. My little boy had extremely bad gas, especially at night. He was very tearfully after every bottle (he wasn't as bad when we used the pre made bottles of milk). His nappies were constantly loose, and he was always congested. X
Sounds more Gas related to me. Maybe even constipation??? But doesn't seem typical of reflux to me. I hope you get some answers and babe gets some relief 💕
Sounds more like just really bad gas
