It has very recently come up that DS1 is really struggling at pre-school - prob Aspergers.
Co-incidentally, on the same day, I saw an osteopath with a back injury.
He suggested cranial osteopathy. (well, he would, wouldn't he?)
Personally, I'm a cynic: "you mean, you wobble his head around and he stops kicking / hitting everyone??" and was too likely to burst into tears to discuss it there and then.
Have seen cranial osteopathy come up here a couple of times recently.
Mumbo Jumbo or worth a go?
