Both of my kids have food allergies.  My son is severely allergic to peanuts.  My daughter is severely allergic to eggs.  Between the two of them, they have mild to moderate allergies to milk, wheat, spinach, mangoes, peaches, tree nuts, ground nuts, dust, pollen and pet dander.  Vegan websites are an awesome source of alternative recipes for common comfort foods, and have introduced my whole family to so many flavours we wouldn't have otherwise tried.  Blessings in disguise and all that, right?
