I have a friend who is a nursery worker. He's also male. He's actually thinking of training to become a teacher (primary) which I think would be fantastic. However, the suggestion that he is somehow less suitable to care for a child (of either sex) than one of the female nursery workers is, I think, outrageous.
To be honest, I'm surprised any of those posters are prepared to send their children to nursery. Or in fact, school later.
Anyone would think that the children were being subjected to a sexual examination - not a nappy change or bumwipe in the toilet!
There is also a thread linking the nursery situation with someone saying that they felt scared when on a beach and a man 'cut off' their exit. I can't quite see the connection between the two - but perhaps that's just me.
