Kids-diagnosed as dairy and egg intolerant!

i would go to a health food store or a Kroger's They normally have a LOT of things that are made with soy or rice instead of milk and eggs. Things like milk, cheese, ice cream, smoothies, yogurt. And other things

I drink rice milk and almond milk. Try the sweetened vanilla or chocolate varieties to get your kids used to the taste if you want, but I drink the vanilla unsweetened now, and think it is really good. They are both at health food stores, or in the health food section of the grocery store. Both are good sources of calcium and vitamin D, and I have used them instead of regular milk in many recipes with good results.

To substitute eggs in any baking recipe, just use any of these instead of one egg:

1 Tbsp ground flaxseed (flaxmeal-found in any grocery's health food section) + 3 Tbsp water OR
2-4 Tbsp soft tofu OR
1/4 cup mashed, very ripe banana OR
1 tsp starch-based egg substitute (or follow package directions) OR
1/8 tsp baking powder added to dry ingredients to replace the leavening action of each egg or egg white

You have to try it out to see which works best in each recipe.

Also, I would recommend going to the library to see if they have any vegan cookbooks. Granted, you are not looking to be vegan, but all of those books will have egg and dairy free meals that you could easily add meat to. I just got this book from the library: "Raising Vegetarian Children" by Joanne Stepaniak and Vesanto Melina. It describes a "total vegetarian" as a vegan and has a ton of recipes. Don't read the whole book, just skip to the back to see the recipes for egg-free and dairy-free muffins, shakes, cookies, pizza, noodles, tacos, etc that are really kid friendly.

Otherwise, if you go into a health food store and explain your dilemma they will be more than happy to help you find snacks, meal ideas, etc. that will work for you.
