I'm concerned about the behaviour of my six year old daughter.
When she is at school, or playing with friends, she seems to be very well behaved, and she usually gives a very positive impression to the people she meets.
But at home, she can sometimes be an absolute demon. She will wail and scream if things are not absolutely to her liking, or if she cannot get assistance with play activities because (for example) we parents are currently dealing with one of our other children. She sometimes says horrible things, like wishing family members were dead, or (last night) that she would report Mummy and Daddy to the police, and get us taken away, just because we insisted she go to bed at her usual time.
Last summer, she ruined our family holiday by screaming and crying for hours nearly every day because she didn't always get to dictate what activities we did that day. Punishment often has little effect, because as we impose punishments, she escalates her bad behaviour, for example by picking up nearby objects, and starting to throw them, or by kicking at the glass plates in our front door, forcing us to intervene.
She is not like this all the time - on some days she is as good as gold and a pleasure to be with, but there seems to be neither rhyme nor reason to her tantrums - sometimes they occur on the same days when she has had presents bought for her, or has been taken out somewhere as a treat.
This behaviour causes friction between my wife and I, because I am appalled by these episodes, and feel that we need to do everything we can as parents to prevent them from happening. My wife, though, seems to accept this behaviour from our daughter far more than I do, and whilst agreeing that it is unpleasant, chooses to emphasise the days on which our daughter is well behaved. Even after extreme bouts of bad behaviour, my wife seems ready to immediately forgive our daughter and forget, whereas I feel that there should be some lasting consequences, to provide a disincentive to act like this in future.
We have an older son, and he does not behave in this way at all, but his younger sister's behaviour has driven a wedge between them, and we are likely going to have to move him into a different room soon because of it.
I would like to know whether forum members have any experience of this sort of thing, and if so, how you dealt with it.
