If he can tell his parents that he feels bad because they are going out so much, maybe the series of temper tantrums won't begin in the first place. The ultimate resolution of tantrum behavior is when a child can talk out differences of opinion. The discussion may be heated and emotional, but throughout it all both must remain in control, refrain from putting the other down, and try to negotiate a solution acceptable to both. When a child is too upset to talk, encourage the release of her anger by such physical activities as running around the block, going in a closet and screaming, drawing a mean face, dancing to records, or jumping up and down. Remember that one's goal should not be to repress or destroy all angry feelings in children, but rather to accept the feelings and to help channel and direct them into constructive ends.
Unexpressed anger tends to build up and emerge in an explosive way later on.
Train your children how to talk themselves out of their anger. Teach them how to counterbalance frustration and insult by saying quietly to themselves calming thoughts, thoughts of self-control, or thoughts which put the situation into perspective. It is not worth getting bothered about. Understanding a situation can help a child understand the cause of the anger, and begin to calm down. Your explanation can include telling the child how you feel, and asking for consideration.
