We did Tracy Beaker, and it did rub off a bit, but my dd was 6 and did understand that TB was the way she was because her mummy didn't love her and left her alone. I stressed that children who were brought up by mummies and daddies who loved them didn't need to shout to get attention. It helped us to reinforce family values, if anything.
I also explained that care homes aren't like this in the real world. They're much more horrid (just in case dd wanted to run off and join one...like a commune or something).
We inherited the words 'bog off' from Beaker which was a bit worrying at the time. Let's face it, it's hardly uplifting, but coming from a council estate in my youth, I was using much worse language at 7. And it is kind of useful for those f-bomb moments when you have to say something to express your rage but want something innocuous in front of the kids.
I don't watch the 'stupid' programme, because I don't like the word. That may sound a bit puerile, but I can hardly say 'we don't say stupid in this house' then let dd watch a programme that's based on the word. Anyway, it's pretty horrid!
The JW books are all on dd's bookshelves, but we've read none of them. We started with one but it had a scene in where someone gets mugged or attacked (can't remember now), but was shocked at it, so put it away and 'lost' it. They're being kept til dd's older though as she may decide this is her kind of thing.
Hedz, on the other hand, is really funny. It's a bit irreverent and a bit daft, but I quite like that. I love the Rooney twins and the Tiger Woods sketches. Though my favourite is Gordon Ramsey. For weeks we went around saying 'makes mommy angry...but mommy stays calm'. DD thought it was hilarious.
