I've been dragging my feet on dealing with possible non-food sources of gluten. My daughter had chronic mild stomachaches, which have mostly cleared up since going gluten-free, and she has never had a noticeable gluten reaction since then.
Because she doesn't react (or at least not in a way we can clearly see), it's hard to know how careful we need to be. Do I need to worry about things like Children's Tylenol/Advil, shampoo, sunscreen, etc.? I know the official answer is "call the manufacturer," but did you really do that for every product your child uses? Is there a way to know which ones to be suspicious of?
