I'm at my wits' end. I have three kids, two boys aged 9 and 6 and a girl of 3. The boys hate each other and have done since the younger one was about 2. Their behaviour is getting worse and worse as they get older. It's now at the point that we can't have any day trips or even a trip to the park without their being a massive melt down. We have a 'three strikes' rule about naughty behaviour so it's meaning that we are more often than not abandoning days out and going home. My poor daughter misses out on everything because of her brothers. My second boy is particularly aggressive and impulsive. He never listens to anything we ask him to do and loses his temper on a whim. He's always had problems at school with lashing out at other children and generally doing daft and impulsive things. He often says he wishes his brother was dead. I'm worrying now that they are older the squabbling is turning to fist fights. I've had to abandon a trip to the park today after they ended up punching each other and rolling around on the grass after a game of football went awry. I feel like me and my DH set clear boundaries about behaviour, there are consequences for not behaving and rewards for doing the right thing but still our kids are like a rolling riot when we go out. What else can I try?
