DS is going through a biting phase at the moment - two children his age have gone home with bite marks/ a bruise in the past week. In the past i have noticed that his biting tends to co-incide with teething and i have noticed that he has two teeth (canines) coming through. I'm not making excuses and clearly he needs to know that biting other people is not acceptable behaviour. We usually say very firmly "No, you don't bite people, biting hurts" and make a fuss of the person he has bitten. We have also begun asking him to 'kiss' the other person to say sorry (he can't say sorry yet). However, our childminder used the naughty step yesterday, which i am slightly uncomfortable with for such a young toddler as i'm not convinced he understands or that it really achieves anything. She sat him there for one and a half minutes (which i know is standard for this type of punishment - a minute for every year). At first he got back up, but then he stayed there apparently when she sat with him. In the evening he was a lot more unsettled than usual, like he wanted reassurance from me. He wouldn't leave me alone and wanted constant attention. He just wasn't himself, very whiney and fussy. I don't want to be soft on him, but wondered what others thought about the naughty step for a young toddler. Does it work? Is it an effective punishment at that age?
