Thanks for the awesome responses ladies!! I never even thought about just emailing/phoning the company, lol.
My pediatrician had suggested that I try soy, as the milk intolerance in his opinion wasn't "really bad", only kind of bad, so it was worth a try. As well DS2 has such watery stools that the diaper soaks most of it up so it barely looks like he pooped, and it is causing such bad diaper rash
I didn't know about the negative side effects of soy though...I guess if he tolerates the formula some heavy research may be in order to decide if it is worth it, sigh.
Unfortunately he woke up from his nap with red marks on his cheeks (possible starting ezcema...) so see how it goes in the next day or two...
