When children are allowed to help make family decisions, they tend to be much more supportive and happier with family life. Also when allowed to help make rules, they will follow them much closer than if rules are forced on them. All these add up to a happier home for all.
When a child makes a mistake or fails to accomplish a certain goal, we must avoid any word or action which indicates that we consider him a failure. 'Too bad that didn't work.' 'I'm sorry it didn't work out for you.' We need to separate the deed from the doer.
