My eg/pg ds6 had ot for 5 yrs. He was born with severe SID so we did the brushing from about a year to 2.5/3 yrs old on and off. It helped us with the severe tactile, sensory defensive, and attentional issues.

I'm wondering now whether we should renew it again for the calming factor. The trick, though, is that you've got to use the brush in a certain way otherwise it can aggravate the situation. There's a knack to it.
