Many family dysfunctions start out as minor problems which get out of hand.
For example, a discipline problem with a preadolescent may lead to physical punishment which becomes abusive. Unfortunately many families are not skilled in communication problem solving, they are too busy with other things. Having better family communication and solving problems as they arise can prevent many dysfunctional behaviors. A proven way of doing this is through regular family meetings. This involves getting together just once a week or so to talk about how things are going in the family.
