My ds6 is exhbiting those same behaviors now. It's almost like he doesn't know how to play without being rough. We are currently doing counseling and group activities to promote the social interactions. I agree that sensory issues could also be at play in our situation. DS6 does seem to need constant physical contact. We also talk a lot about other people's personal space (bubble) that he must not cross without permission. That does seem to help.
