USA Today has said television, video games and fear of the world outside the front door is creating a world where today's children are under "house arrest." And White Dot, the International Campaign Against Television (http://www.whitedot.org) is trying to turn back something called "BabyFirst TV" which, White Dot says, is out to turn infants into "cot potatoes."

It's doubtful if BabyFirstTV, the world's first 24x7 TV channel exclusively for infants, is exactly what the pediatrician would have ordered.

The channel premiered in the US last week and its promoters claim that it offers "completely safe, commercial-free and appropriate content" for viewers between six months and three years.

The book's author, Lucy Jackson, argues that modern children spend most of their lives strapped into buggies or sitting square-eyed and round-shouldered in front of the telly. This, she contests, leaves toddlers unfit and often overweight. Her remedy, outlined in Childsplay, is 'home classes' of movement and fitness 'from birth to five'.

But are toddlers really in danger of becoming cot potatoes? Or is this just the latest fad to be sold to mums already overloaded with advice on how to bring up the perfect child?
