That sounds really rough Nimra. Have you spoken with your child health nurse or GP about this? They might be the best to advise you. To my knowledge, the only really substantive difference between dairy-based formulas is iron content, and I guess some may get bunged up on those with more iron.
All the best
I took bub to my GP, but she said there is no cure, she said im already all possible things to make bub comfort. she said wait for two months if he doesnot settled she will refer him to specialist.

but after reading this forum i feel like to change the formula but which formula, I got stuck .
