Two hours per day presumably (rather than per week).
I note they say phased, so my four year old doesn't get as much time as a sixteen year old, which sounds farcical, but even so I think this sounds like a joke, and the whim of the week.
A few reasons - most movies are ninety minutes long. My five year old gets a movie most weekends, I'm a harsh parent, but would hardly turn the DVD off cos he'd used up his quota.
Some programmes are educational. Alphablocks is a hit in my house, before the age of three.
As mentioned, what do I do with the toddler when the older two are watching television.
I don't have older children, so am sure someone else will correct me, but isn't a lot of schoolwork done on the computer these days {cringe at how old this makes me sound}
And lastly, even if they suggest this, I suspect many modern parents will not abide to it. I'm not an amazing parent, but I'm by no means terrible, and the television was a blessing when my children dropped their naps and needed some time to zone out. (No, they did not want to bond with Mummy and a book if that is what is suggested.) It was also a lifesaver for when the second and thrid children were born. My middle child was totally disinterested in television, and trying to settle the baby/feed the baby/ stop the baby screaming was so difficult when she didn't want to watch anything, but just wanted my attention. With my older child I relaxed the rules, then reclaimed them when we were into a routine.
No no no no no.
Plus also as said, so not lastly before then, it gets me five minutes peace, and stops me losing it and shrieking like a harpy. I suspect not even a gobstopper would otherwise buy me this.
