My DD (3yrs old) has recently been diagnosed with SPD and we went to her first chiro appointment today. The chiro mentioned that DDs big tummy is not fat, but actually just bloated. She mentioned that Gluten (among other things) would most likely be the cause (its common is SPD kids).

Where do I start with all this? Is there any tests I need to do to confirm gluten/other intolerances with a GP/Ped? No idea where to start and don't want to start down the line of 'can't have this and that just because it *may* be an issue)

TIA!
