Help for newly diagnosed

[Guest guest]

I'm looking for some advice to give to someone in England who has a 3

yo son just diagnosed with ASD. The parents both want to start the

GFCF diet and have tried it in the past but this is the problem. The

child self limits to 12 food items, all casein or gluten. When they

tried the diet he starved himself for 3 days before they caved. By

the mothers description he is a gut kid so I know the diet is

critical.

What can they do with this? (I'm clueless, my son took to the diet

pretty easily.)
