I went to see a CM last night and one thing she said which slightly bothered me is that she has the tv on in the lounge all the time as "background" noise. The playroom doesn't have a tv and she said that if she spots a child not moving from the tv she will encourage them to go and play with something (by diverting their attention).
I'm interested in what other CMs do re tv. I'm not sure whether I'm being picky. DS's will be at nursery for part of the day so it's not as though they will potentially be watching it all day.
