There's a sitcom which has been running for a few years now, called Outnumbered. I've never been 'into' it, but every so often I get drawn into an episode. I think they actually did the last series earlier this year and the ones currently running are repeats. There are five series altogether so you get to see the kids growing up. The middle kid, a boy of about 12 I think, is hyperactive and has a tendency to lie and go on flights of fancy. The eldest is a cynical teen, and he's basically the straight man of the kids. The youngest is a little girl and she is hilarious (I think)

There's quite a lot of improv, particularly from the kids. That way the kids give a more naturalistic performance and then the adult actors react to them. The basic premise is that the two parents are essentially outnumbered by the three kids.
