are you asking because body brushing hasn't worked?
or because your ds cannot tolerate it?
we had a sensory programme outlined by BIBIC years ago, which included all kinds of different textures for dd1 to get used to, as she was so sensitive to textures.
eg we used a warm flannel and a cold flannel, and worked mainly on her hands to start with - each finger, one at a time, alternating warm and cold (saying what each was as we stroked/rubbed/massaged - it was kind of a combo of all 3! - each finger), then the other hand.
if she was in a good mood, we did the same with her feet.
deep pressure massage is suposed to be good, as are thing slike weighted blankets/waistcoats/lap covers, but I haven't used any of those.
