I'm a father of an autistic 4 year old girl. Removing screens entirely from her has caused her to develop language and sleep better. I can't say why or how but I highly recommend just avoiding screens (including TV's). The hardest thing too I think causing all this is us as parents tend to hover much more than our parents did to us.
