My dd is going through a hiting and occassional biting phase. DD is a lovely little girl and seems to have a big personality that I love however for the last few weeks she has started hitting out regularly. At one point she would bite me I would firmly say 'No, don't bite' and she would hit me!! Her 5 year old cousin who is a lovely boy without an aggressive streak)is getting the brunt of this at weekends and went home the other week with weals down his face!. Saying No doesnt seem to be enough so I am trying to get dd to start to say 'sorry' and kiss better. Is she too young for this type of lesson? If so what else can I do I want to nip this in the bud ASAP.
