Well, there may be some apps out there that would help with OT skills. Maybe talk to his therapist and see if they know of something. See if he would use those apps a certain amount of time if he had an iPad. If you go with it for the grandparents, would the other ones get him accessories? Case, chargers, itunes gift cards, etc. Other suggestions: bicycle, skateboard, certain brand name of shoes or clothing you wouldn't otherwise buy. I know 9 year-olds are liking some of the spy toys out there. Maybe a trip to Laser Tag with friends or siblings.
