5yo DD has all of a sudden started saying 'I hate you mummy' if she is having a tantrum or doesn't get her own way. I totally get that she's lashing out, she doesn't mean it etc but what do you say? Part if me wants to ignore it so that when she sees it doesn't get a reaction she will hopefully stop. But part of me wants her to realise what a horrible thing it is to say and that she shouldn't use hurtful words.
