Formula milk

Ftm

My 6 months old son had FM first 2days of life then only BM till now.

We tried several formula brands with him but he vomited every time after 2 hours of consumption

None of the formula suits him.. otherwise he is a healthy baby.

Has anyone faced this situation?

In such when starting solids did you avoid any food ?

Pls share your experience. I can work without formula but just not sure if I should avoiding any food group since formula didn’t suit him ?
