#asktheexpert Hello Doctor, my daughter is going to be 2 year old in Aug this year. A new behaviour pattern I have been observing since last 3 months. She hits/ slaps people around when she is adamant on something or sometimes when is amused too. we tell her this is not funny and say no please do not do it but it is like a game for her and she kind off laughs and enjoys it. Is it normal and what should we do to combat this habit of hers? Thank you.
