Gluten free, dairy free

I can't remember if I've mentioned this before, but I am thinking about gluten free/dairy free foods.
I have been researching it a couple of months, but i don't dare start cos It wil be a 100% turnaround for us. The extra work! etc.
I started thinking about it a couple of years ago when I was reading up about asd. It seems people with asd or adhd kids who have had awful behaviours, swear that GFCF (Gluten free, casein free) diet has improved their lives no end.
Then as i investigated more, I noticed that almost every large family has at least one GFCF kid. These mothers manage somehow!
And the health benefits seem to be for all!
I am going to try soon, honest!
I made some gluten free rhubarb crumbles once, that was nice!
