My DD has SPD (sensory processing disorder) on top of her HFA. We've been doing sensory diet activities with her since last October.
We had a swing for YEARS and it helped not only with sensory diet for my daughter but it attracted kids from the neighborhood to come over to play, allowing her to interact and have social contact. She also used a weighted vest for awhile, has had a ball-seat at school at times, and also a wedge at times (to sit on). We have tried a lot of little things over the years, with some success. I think she has also just started "growing out" of some issues. She uses the trampoline constantly though, and that is definitely sensory related, I think.
Yes, our OT has me doing the dry-brushing with DD. She also wears a pressure vest at her preschool. We're planning on getting a swing for Christmas.
My son had a sensory diet when he was younger. It helped a lot. He still has some issues. We use UnderArmor compression shirts to help him with his tactile senses. He took showers instead of baths. He still takes showers, but he enjoys them now and stays in until the hot water runs out. I would rub his back. He had activities at school. I wish remembered more. It's been a lot of years.
