Hi,
My daughter went through the same thing; her diapers were the worst! There is a way to make homemade formula that has worked for a lot of moms I know. I tried it as well, but my daughter could not tolerate the milk protein (usually the problem for babies with an intolerance to cow's milk formulas). We did goat's milk and she was a totally different baby. She is now well above average in height and weight (she was considered "failure to thrive" at 2 months). I (at first) was uncomfortable about trying anything that went away from the "norm", but it gets to the point where you become desperate and willing to do just about anything! Plus, when I saw the results, I was hooked! :)
