My dd is 9 with AS and apparently according to the OT Friday the sensory difficulties are part of the AS and not a standalone dx! I always used to say it as separate.
Anyway some good ideas she gave me were:-
Dd to wear a heavy back pack to and from school (deep shoulder pressure)
To help with sleep,relaxation use a seeping bag and once dd's in it stuff with pillows for that deep pressure that she craves
Instead of buying a weighted blanket get the heaviest tog you can get
Really boring but she said let dd have bowls filled with rice, cornflour (mixed with water), pasta, jelly etc
Also when dd is hyper I have been giving her pressure on her shoulders by pressing down on them and it's really helped.
Once we get our sensory diet I will add more
