One of my best mates is 1 of 14. Her dad, one of the nicest people I've ever met, was a scaffolder by day and a bouncer in the evenings so he could support his large family.
Not all large families are benefits scroungers!!
As I said on another thread....have you watched 16 and counting? 16 kids, dad works full time running his own bakery, mum worked in the bakery for most of the babies lives. They are a lovely family, don't claim benefits, mum and dad run a ship shape house....
Maybe the TV channels should concentrate on these kind of families even if to just lower your blood pressure :-)
