Still no milk

I am usually so careful about reading labels before I give Caleb anything new. Today I gave him some french onion sun chips while I was making lunch. He came over to me saying ouch! ouch! so I looked at him and ran for the benedryl. Later I read the label ingredients: Whey protein(milk), dry buttermilk, whey(milk), sour cream, soy protein (he's also alleric to soy), cultured whey, mozzarella cheese, skim milk, and cheese cultures.

Oops!!!!

He is fine now but I do feel like the worst mother in the world!
