Hi, I have a question regarding my 3 month old

Patient: Hi, I have a question regarding my 3 month old. He has been formula fed since birth, after his first month Every time I formula feed him he will cry and refuse the bottle Because it gives him discomfort. It is a constant fight with his stomach, his stomach cramps up doesn’t allow him to swallow the formula and it becomes stiff it is asif his organs are bouncing off his stomach, so he kicks and he squirms from the pain and he can only keep his body straight if he bends or tries to sit his stomach pushes him. I have tried four different formulas and this keeps happening. Any ideas what it could be?

Doctor:
