Oh P. I feel your pain!!!!! At one year my little guy was diagnosed with allergies to Peanuts, Wheat, Eggs, Milk and Bananas. I tried, for a while, to avoid soy as well...but, wow, that was hard!!!! I purchased an amazing cookbook called Spohie Safe Cooking by Emily Hendrix. (You can look for it on Amazon, or check out her website at www.sophiesafecooking.com) It is free of the top 8 allergens. So, NONE of her recipes include wheat, soy, milk, nuts, eggs, or shellfish. There are a few that contain beef--which you can substitute with ground chicken (be careful about turkey--because it can contain either wheat or milk--I forget which!). There are a few with cornstarch....but not many.
The cookbook is great. The recipes are easy--and really tasty. And, the best part, in my opinion, is that the ingredients are weird things you've never heard of! You will likely already have everything you need in your pantry. The only thing I had to do was buy Apple Cider Vinegar! (and, hey, that's an easy one!). She uses oat flour in her recipes which is just oatmeal tossed in a blender!!! Easy!
If you need some more help...or you just want to talk with another mom who has been there, feel free to email me! I've got some recipes of my own too! Good luck! Traci
