Hi,
Has anyone had experience with the gluten free, casein (dairy) free diet for children with Autism?

I have been looking into it for my daughter after I was told about some of the benifits. I am keen but nervous at the same time about starting it with her. I have been told it should reduce her anxieties, improve behaviour, decrease frequency of infections, reduced tactile defensiveness and potentially increase communication due to reduced anxiety and increased focus levels.
But, it is a huge change in her diet (It may also exclude Soy, Chocolate, egg, yeast, peanut and citrus fruit) and the assessment to get started is very expensive. I know I am always the first to say cost isn't important if it will help her but Its a huge commitment if it isn't going to work.

So I am trying to get as much feedback good and bad from as many people as I can before I commit to it.

Any comments appreciated. Thank you
