Free Clinics for Children

My eight-year-old son may have mild autism (he flaps his arms, but speaks very well) and he was diagnosed with sensory processing disorder and gets easily frustrated and has a short attention span. He has had sensory integration with an occupational therapist and vision therapy, but I still feel like something is missing. As a baby, he never stood up or cruised along furniture, but he went straight from crawling to walking in one day. He also always slept on his back and has a asymmetrially shaped head. I am interested in ABM and Cranial Sacral Therapy to help him to be more in-sync.
