I did the the son-rise start-up course a few years ago, and subsequently a part-time home programme with ds2, starting when he was 4. Like any therapy/intervention, it doesn't suit everyone, but we found it really helpful, and I've heard that the boss of phones4u has donated LOADS of money to fund British parents to do the initial start-up course. A friend got 100%, but I think it varies. Sorry I don't have a link, but I'm sure if you google son-rise you can find the info. Hope this is of use to someone.
