I was trying to be sneaky because soy is so much cheaper than Nutramigen. I stopped breastfeeding about 4 weeks ago. When I was supplementing though I would do about half soy and half Nutramigen. Now that I stopped breastfeeding, I tried more soy than Nutramigen and now have eliminated soy completely because she's intolerant to it now that I started giving her more of it. When it was half soy half Nutramigen she wasn't having as much of a reaction. She usually only pooped 1/2 times a day. Now she's pooping 4/6. We stopped giving her soy (per pediatrician) on Wednesday. How long do you think it will take for her to stop pooping as much? For those with older babies did they grow out of milk and soy intolerance? If so what age?
