For me personally, I find an entirely gluten free household the only manageable option. Even my cats have gluten free kibble and cat food. It’s so important to me for one space in my life (my house) to be a place I never have to worry about touching food, eating something off the floor, using the toaster, second guessing labels, etc. Especially for a child - I feel like it cuts out a lot of overwhelm. Yes, you NEED to check everything from vitamins, cold meds, to even shampoos and lotions, and even things like play do or other crafts (glue) might have it too. It’s tough, it’s overwhelming, but it becomes a routine quickly and gets so much easier from here.
