Goat's milk can be an issue for kids who are truely allergic to cow's milk, as it is very close in protein structure. My kids are allergic to: Wheat/wheat gluten, soy, cow's milk, eggs, nuts, and the list goes on from there.
Toast. Rice bread, sunflower seed butter, and jelly, jam, or apple butter (home made, so no high fructose corn syrup)
or Wheat bread (for dd), sunflower seed butter, and honey
Hot cereal. For ds, there are some mixed grain cereals out there. We add real maple syrup, or dried fruit, cinnamon (he gets one shake, I get one shake), nutmeg, etc. Whatever he's in the mood for. We use rice milk in our house, and, though I usually personally feel like rice milk tastes like library paste, it's actually preferable to cow's milk for me, in hot cereal.
or Dd eats oatmeal or steel cut oats or cream of wheat. Same toppings, usually as above, with rice milk always.
Puffins are a HUGE hit in our house. They are a corn cereal kind of like quaker corn squares. They are quite yummy. THey also make a honey rice version that dd loves.
Gorrila munch is good. LIke kix, but only ONLY corn and, um, quite a bit more sugar.
Fruit, fruit, and more fruit. We eat fruit like crazy in our house. Pineapple, oranges, apples, grapes.
Ice, fruit, and juice smoothies. They go crazy for them. Like a "shake" that they can actually drink.
Mmmmmmm...we make pancakes or some other kind of breakfast once a week for dinner, then save a few days worth for them for breakfasts, as well. I have a GREAT recipe that uses ener*G egg replacer, smart balance, and rice milk and is quite edible, even for regular milk people. I now use garfava flour, too, since we've found out that ds is allergic to wheat/gluten.
I know there's more...
