Is it diarrhea? As in, is he going a few times an hour? One thing I can adivse on with switching formulas is this: Never do it all at once. As in, don't just start a new formula. You have to ease into it. Changing all at once is a huge disruption to their systems. I too had my first son on nutramigen for allergies. When it was time to start introducing a milk based formula back in to make sure he could tolerate it, we did this. I mixed 4 cups at a time. So 15 scoops nutramigen and 1 scoop of new formula. Every time I mixed a new batch it was adjusted by 1 scoop. I am now introducing goats milk for allergies as well and doing it by a half oz at a time and over a lengthly period. But with formula changing be careful. It causes too many problems. We tried soy with both our sons and caused terrible diarrhea. But gradual changes are best. Hope that helped.
