Another approach would be to look at Ross Greene's work:

The Explosive Child (I know he's not so explosive anymore, but this is still a good book about addressing emotional-behavioral issues, and specifically includes some discussion about hypersensitivities). This is a very different philosophical approach from the behaviorally-inspired ABA, CBT, etc. therapies.
