It's called Outnumbered and it's on BBC1 at 10.35. It's a new sitcom about the every day ups and downs of raising a young family. The couple in question are a teacher (him - some bloke from HolbyBlue I think it is) and a part time wedding planner (her.) They have an 11 yo about to start secondary school (I can relate to that) and a 7 yo and a 5 yo. The youngest has nits apparently!! (I can relate to that too!!)
I think the guy's portrayed as a hapless Dad, struggling with a young family.
Might be shite but only one way to find out.
