Hi AVTM.
I am a massive adovate of cranial osteopathy, as it has worked miracles with our DS1, who has a "single suture" one of many ways that craniosyntosis occurs. The lady we see also works with children with autism and other S.N's. She actualy travels to a schoool with the other osteopaths where the children can be treated.
When DS2 was born, thankfully he didn't have craniosyntosis (we have a 1 in 2000) chance of it happening again to the next baby. I still took him, and it did appear there was help that could be given, he however only required 6 treatments. I can't say there was any obvious improvements, but our osteopath said she could feel the tightness go, and I'm glad we took him.
What I'm trying to say is, they'll always be the people who say its rubbish / doesn't work. I think I would've agreed had I only taken DS2. However, knowing what it did for DS1 (he didn't talk or sleep until 2, and I really mean didn't talk, no baby babble, lost any muma / dada development age 1. He never slept a night through from birth until 24 months) I would really think it'd be worth a shot with your son, especially as he has autism.
We kept a record, and it's amazing what achievements we have made. DS sleeps a good 10-12 hours every night, and also now talks very well. It will be a treatment that he will always need until adulthood as his head grows, although the appointments will be more spaced with as he slows down growing.
When you're looking for a C.O. ring around a few and ask if they treat children specifically, be prepared on your first visit thatyour DS may not like his head been touched. Not that it hurts them, it's just kids! Our DS still wriggles off halfway through! Take a fave toy or book.
Our first appointment was almost an hour and now they are just 30 mins. We have also found DS can be very sleepy afterward, or have a real energy burst (in a good way, not a hyperactive thing)If you want to know anymore, please CAT me.
I really hope it works for you and your DS. x
