I have been doing an elimination diet with my daughter. We keep having to stop due to other complication with her needs and I wasn't able to tell what was pain/illness or food related behaviours.

If you havent done it yet I think it is well worth it. We started with finding a dietician who gave us the relevent info to start (you need a dietician who specialises in it, the first dietician we went to wanted my daughter on a vitamin supplement which contained artificial colourings????go figure???
My understanding is FAILSAFE /low chemical diets and elimination diets are basically the same.

You should know within the first 2-3 weeks of detox if your child is allergic to anything and looking at the big picture, The tests should take no more than 3-4 months to get through which isnt a big price to pay if it means a better life for your child and your family.

Good luck
