Dd is 7 and is a bright, funny smiley little girl and teachers all say she is a model pupil. She has friends but can sometimes prefer her own company. She has always been very fiery and very quick to anger. She has an older brother who is very gentle and good natured but occasionally does like to tease as all big brothers do. Of recent times her outbursts are becoming more violent and this morning she struck me and kicked me because she couldn't have own way. I am sat here in tears at a loss at what to do. She had calmed down and is merrily eating her breakfast like nothing has happened. While she was cross it is if she takes on someone else's persona and will say the most horrible things and will almost be as though she is acting a part. She is beginning to frighten me. Other things maybe worth mentioning is that she is a very poor sleeper as in she wakes very early often at 5. Has allergy problems. Keep wondering if a vitamin deficiency etc could be causing this but aware I'm probably clutching at straws.
