Do everything your heart tells you to do, within reason because regret weights tons.
When your child has an illness with no specificlly identifiable cause or cure, it's no so easy to know what do you do? So, in my case I did what I could. On the therapy side, if there's an acronym for it, PT, OC, ABA, PRT, FT, TEACCH, RDI, DTT....we tried it! On the medical side we've tried everything that wasn't obviously dangerous (and didn't make me feel like I was treating my child like a lab rat - which I did by the way.) and offered hope we might be able to put the puzzle together and help Nick; hyperbaric chambers, chelation, bio-med treatments, Secretin, special diets and some things I can't even remember. Some helped a lot, some a little or for a while. I don't know how it will be for anyone else, but twelve years into our journey there is no magic bullet for Autism, at least not yet.
