My theories are that both the GAPS diet and TH are right.
That the kind of ASD my DS1 has (ie mild Aspergers) is caused by and fixed by the exact same thing my DDs dyslexia is and my DS2s dyspraxia is.
DD did vision therapy and retained reflex therapy before TH. They didn't work at all. The vision therapy Robin prescribes is much more effective than what my behaviour optometrist did.
And there is no relationship between retained reflexe therapy and the neurodevelopment therapy TH prescribes. They are not at all the same.
I believe DD would have qualified for a dx of APD prior to doing auditory integration training and she no longer would. But obviously that is only speculative as she wasn't seen by GOSH.
Retained reflex therapy did help DS1. But we went to an excellent place to do it. And the same place didn't help DD.
But certainly the RRT the BO got DD to do was total rubbish. As was the vision therapy he prescribed. Were we just unlucky? I don't know.
Have we just been lucky with TH? With it helping both kids? (DS2 isn't doing it yet). I don't know. But so many people on this thread are happy that it seems likely that it's not just luck.
This term my school tried the TH stairs exercises on 10 kids. They are so impressed with the results that next year they are going to do it with 40 kids.
