I would recommend finding an OT to work with you to develop a sensory diet. At various times, we've used Wilbarger dry-brushing, a weighted vest, chewies, an electric toothbrush, a mini-trampoline, a swing, a kicking strap for her chair, and fidgets like a Koosh.
I would recommend getting a good Occupational Therapist and getting a sensory diet started. We used the Wilbarger Brushing Protocol, joint compressions,weighted blankets. A good OT can evaluate your child and steer you in the right direction. It's never to early to start teaching your child to fill his own sensory needs in a healthy way.
My 2 year old does the same things. Our OT had a bunch of recommendations. I would definitely check in to that. One thing you could try that my son loves is a vibrating teether. You can get one that looks like a bunch of grapes in the baby section at target or they have some at babies r us. It seems to help him.
Thanks! I've been thinking about chewies but I'm not sure if its worth spending money on. I asked his teachers to try them at day tx and he didn't use them. Know of any great ones?
Sounds like he needs increased sensory, check with OT. Research sensory input items on line. If your crafty you can make some cheap yourself. I have started to make things myself and even sell some.
