Hypoallergenic formulas for cow's milk protein intolerance

Katie
The doctors believe my son cannot tolerate milk protein so we've been trialing hypoallergenic formulas. He flat out refused nutramigen so that one's out of the question. He wouldn't take it even mixed with anything else. He takes the alimentum ok but after being on it 2 full weeks I feel like he's super gassy and uncomfortable all the time. He grunts and squirms all night long. His reflux seems a little better and he's overall less fussy than when I was breastfeeding but the gas is killing him! Has anyone else had this problem and what did you do? (Besides gas drops and leg bicycles which I'm already doing) gerber makes a hypoallergenic formula... anyone try that?
