Formula recommendations please!!

R

I just recently had to switch from breast feeding to formula (my supply was very low not even close to enough). My son is 3 weeks old. So far the brand we tried upset my sons stomach he would spit it up every time we gave it, had diarrhea, and was very irritable with bad gas. So we need to switch! I know there are so many kinds just wondering what everyone recommends.

Thank you!!
