<<Disclaimer: Verify this information before applying it to your situation.>> Thanks to all who responded. I am so new at this and now it seems sily that I even asked this question in the first place. I should just call the 1-800 numbers on the products which I have done a lot of this last week. As you all informed me: all formulas made by Enfamil are GF. My son is on Similac so I called them and they are also GF. That was a relief!!! Thanks, Melinda
