I've just been told by his teacher that my 4 year old has been exhibiting "bizarre" behaviour at school over the last few weeks.This includes spitting at dinner ladies, charging at other children and generally not sitting still. I am really shocked I've never even seen him spit! Im also horrified and want to stamp out this behaviour swiftly. I have had brief chat with him about his behaviour and will have a more indepth chat tonight. His birthday is next week and I am seriously considering not celebrating it if his behaviour does not improve at school between now and then. Do you think this is too harsh? I really want the message to get home that his behaviour is completely unacceptable.
