There is some contentious stuff out there about high levels of tv watching increasing the chances of a child becoming autistic. What if however children with autism/autism traits are more likely anyway to watch tv. I don't know if that is true, I'm just throwing it out there for debate.Possibly more time stuck in front of the box would mean less time engaged in imaginative play.I was a toddler in the late 50s/early 60s and apparently watched a lot of television. Nowadays a toddler watching lots of tv or videos would not be that unusual, but I'm not sure it was the case back in the late 50s/early 60s .
There is, of course, the other argument that continuous watching of TV will gradually erode your ability to think and make independent decisions.
