I avoided all the typical foods at first, as well, and gradually integrated them all back. . . the only thing I found was that refried beans made my son's tummy hurt and that the milk in protein was very hard for him to digest so he spit up a lot. Once I quit drinking milk, the spitting up was greatly decreased. He is now 6 months and my drinking milk again doesn't seem to bother him anymore. Just FYI! :-)
