Its the parents fault in most of the cases, its sad when you see a 2-3 year old yelling F---Off etc, where they can only have picked that up from one of the parents really
It may have been a similar show, where they were also trying to stop the kids running riot, and they showed the Dad trying to read to the daughter, when the Mum comes in and starts screaming "Dont f__ing read to her now, f__ing Eastenders is about to f__ing start"
Lovely behaviour, and they wonder why the kids act up.
And on those shows, I wonder how intrusive the camera crew are, do the kids play up even more ??
