An upsetting incident at school today. My 4 year old bit another child because they were trying to take a toy off him. He was quite rightly told off for biting but then the teacher lectured him about sharing and told him to give the other child the toy. He refused and...long story...was sent home. I'm very clear that the biting was wrong but as far as I'm concerned the other child was in the wrong and should have waited their turn for the toy. I have always taught my son not to snatch toys, to ask politely and wait his turn. He is now extremely upset and asking what he is supposed to do when another child grabs his toys. What do I tell him to do?
