Raising a sensory seeker

My 4.5yo son is a sensory seeker. When he gets out of whack he jumps, crashes, smashes until he feels his body again. He was recently diagnosed with PDD-NOS which is on the Autism Spectrum. He is a happy kiddo and as his mom, I'm trying to help him as much as I can. It's difficult sometimes since he has an older sister that tends to feel neglected. I'm trying to include her in his sensory diet so she doesn't feel left out. I want to use this blog to help other people that are going through the same things we are.
