Potato Intolerance

Anyone’s child have a potato intolerance. My daughter was completely addicted to them once we started the diet. I realized she hadn’t eaten anything that way since we took away wheat (she could eat a whole bag of goldfish if we let her!) She had been off them for 3 days and her rash started to clear up and she was eating baout a quarter of what she was eating. I decided to check and make sure that it was potatoes that affected her so I gave her some fries tonight.She was like a wild animal. Giggling and laughing all over the place. She was totally oblivious to us calling her-Suddenly, she crashed. She laid on the floor and started to fall asleep! IS this common? I realize we have to give up potatoes, but can it really affect her that much…This diet is already so hard and she refuses all corn and rice things unless I mask them in tomato sauce. Another quick enzyme question…I gave her acidophilus yesterday morning and she drooled really bad all day. I saw some white flakes in her drool and she was real irritable. Could this be a side effect? What can you feed them if they can’t have potatoes?
