J.S.
I have a 3 yo with Sensory Perception disorder, and I think it's something you should research. My daughter is on the sensory seeking end of the spectrum and it sounds like your son may be as well. Ask your ped to reccommend a good occupational therapist. If you're in central florida, I can highly recommend central florida pediatric therapy associates. They have helped us tremendously. I can also highly reccommend the book "The out of sync child" It's been so educational for me in understanding what makes my daughter "tick" If you ever have questions, please feel free to contact me, I've been going through this for about a year now and I will offer any info I can. Good luck and God Bless.
