DS has always been a pretty chilled out (we have had the odd up and down but nothing major)
however he is now 18 months old and he seems to have embraced toddlerdom whole heartedly over the past couple of weeks
we are firm with him at home - all hair pulling/biting etc is met with a firm no (we get down to his level)
He has never done any hitting etc at nursery until today, when he has pushed a child over three times, bitten another one, and pulled the hair of another child
these incidents were unprovoked - i feel awful and upset as DS has been bitten four times at nursery so i know how it feels on the other side
feel like i am doing something wrong - any ideas or advice as to how to handle this behaviour would be hugely appreciated
