There's lots of stuff in the news at the moment about obesity/ junk food/ kids and exercise.
Official recommendations are that kids should get at least an hour of exercise a day.
I know they get playtime etc at school, but I'm sure mine don't get enough during the week. And DS1 is a bit of a bookworm/computer lover so he's not naturally to be found playing football in the garden.
It does worry me though - anyone got any tips to 'up' the activity levels?
