D.M.
Nutramigen was a lifesaver for us. My son had milk protein intolerance (mucus and blood in stool). I tried to limit diary in my diet - as I was breastfeeding, but it still persisted (and I was told it would take at least two weeks to eliminate dairy from my system). He was suffering too much so we went to Nutramigen. Within three days he was a different baby on Nutramigen. The smell and taste is awful - however, he did tolerate it much better when we mixed it w/ breastmilk for a few days and eventually was happy to get his 100% formula. Good luck!
