This is tricky because scripting can be a child's way of figuring out language and social relationships within shows. My 9 year old son scrips quite a bit. The older he gets however, the more appropriate the scripting is for a particular situation. He also inserts his own name into the scripting while going back and forth with the characters. That tells me there is a desire to have friends and connect, but he just doesn't know how. Anyway, I think that limiting the tv is very important because your son is still young and play is vital to him learning. My son is absolutely obsessed with kids shows and Disney movies and I wish I had found a way to stop the obsession at 2. There is a book that just came out called "Life Animated" which is written by a NY Times columnist whose adult son has Autism. He is a big scripter and the Dad talks about how you can use the movies and shows to connect with your child. It is fascinating and I have found that my son really appreciates that I am trying to join him in his world for a bit and give it respect.

We refer to this as "TV talk" in my house. If he is playing independently and 'TV talking" I allow it as i feel it is him using the imagination that he is comfortable with. If not in play, then I will first say, "is that TV talk"(when he was younger I would say that is TV talk, Dora says that) and change the subject to something relevant. Sometimes it comes out at appropriate times, so for ex: I said "oh that isn't going to work" to my older child and he said "well what is plan B" which was directly from TV. I acknowledged that it was appropriate by saying, "yes just like on Paw Patrol we need to find a plan B to help your sister finish her project. I must say, once we went GFCF the TV talk was reduced dramatically!!

My daughter wasn't a very big Veggie Tales fan so I'm not sure what they teach.I will say some shows do help their speech but maybe see if you can get him to watch some ABC super simple songs or some other more educational videos as well on Youtube.My daughter loves Barney and at 5 and I do still let her watch sometimes but I'm trying to get her to do more educational apps with lots of singing and puzzles which are her interests.Also you can also use his love of Veggie in other ways- Kat loved Barney so I got her a singing toothbrush and I credit the Barney toothbrushing video and songs with helping her learn to do this herself.
Our behavioral therapist told us to pause the videos at times when she is watching and ask her questions before we continue.

My son does the same with Bubble guppies and Im also thankfull at them, because otherwise he wont be using words at all!!!! I think also its a good chance to relate to our kids, I watch the chapters and try to use them on our daily life, for ex. they have a song about brushing teeth so when its time to do so I will sing the song, bring the little toys to the bathroom, pretent do wash their teeth, then I said is moms turn, I wash my teeth and then its my sons turn an he will wash them. At least I will have clean teeth and a big smile as a response!!!!

My son was the same way. He was pretty much non-verbal, until he started watching Caillou, at which point he constantly quoted. Eventually it morphed into remixing lines, and then gradually to independent speech. Honestly, I credit Caillou with a lot of my son's speech development. Quoting was far better than using no words!
