My 2 year old boy is currently sporting a bright set of toothmarks on his cheek, given to him by his daytime playmate, a 2 year old girl.
And do you know, a tiny bit of me, if I'm honest with myself, is not exactly displeased? My son is not in pain from the bite, I hasten to add, otherwise I would not be writing this.
My son and this little girl share the same childminder. My son had a (sometime) biting problem in the summer. We used time out to discipline him, and until this episode he hadn't bitten for months. Last week he was taking medication and was generally not on top form -though certainly well enough to play.
Unfortunately when he and his friend had a falling out over a toy, he bit her, and she bit back - much harder. The childminder disciplined both toddlers thoroughly, with time out and a firm talking to for my son, as previously agreed with me (don't know what she did with the girl, but something similar I believe).
Within an hour both toddlers were hugging each other, and happily played together for the whole afternoon. When I went to collect my son, the mother of the girl apologised to me and visa versa.
Obviously I wish the incident hadn't happened, but since it had, I'm a tiny bit glad the girl bit my son back, teaching him cause and effect. It might make him think twice about biting her again.
IMO toddler incidents like this do unfortunately happen. One loses control - in a way that's unacceptable - and the other stands up for themselves - again in a way that's unacceptable. The behavior is bad, not the toddler - and with the right discipline, IMO, most will grow out of it.
Personally I feel very uncomfortable labelling 1, 2 or even 3 year olds as 'vicious, aggressive etc etc'. They are still so unformed as individuals - some are barely talking in sentences. I mean, would you say, with any commitment that a particular toddler is 'intellectual, secretive or sporty'?
Obviously if they exhibit vicious, aggressive behaviour this should be firmly disciplined, with an apology to the wronged parties. Perhaps I've just led a sheltered life - and if I encountered the sort of child that RobinW and LisaV described, I would have no hesitation in saying 'that child is a nasty piece of work'.
And a last question. Please, please, please note that I am being curious here, not confrontational!!! To all those who have said the parents do not discipline the child correctly at home: How do you know this? Are you basing this belief solely on the way the child behaves in public and is disciplined in public, or do you have other reason to believe this?
