Let me tell you right now that television is a big no no if you want to reach your child. Whether neuro-typical or on the spectrum. This is my son's Occupational therapist pet peeve. I agree with her and I try to limit television as much as I can and I have been fortunate that my son is good once I hide the remote.
Now that I have put in the disclaimer.
I credit a lot of my son's words, play and actions to television with particular bias to the teletubbies and the Wiggles. I nearly cried the first time I realized that he was reacting and responding to something that he saw on teletubbies. The Wiggles introduced singing to him and he is such a singer. He never followed the dancing or actions but he would sing the songs with me after and it would make my heart sing :) Fast forward five years and I did cry to see my son dancing to the Wiggles. It was silly of me, because I have seen him perform fearlessly and wonderfully at school concerts and plays before.... but to see him dance the Wiggles was amazing simply because it was something I had been trying to get him to do for years.
So like with everything else I am here to attest that television can be used to your advantage when it is used in small doses, because it just may be the one thing that gets your sweet child moving.
( Now he is inspired by Yo Gabba Gabba, deal or no deal, family feud, catch 21 and Iron chef. oh and even though he is nine Wiggles still makes is top ten lol)
