Parents should consider at least four aspects of consistent discipline. Consistency from Situation to Situation Results are predictable. Your predictable and consistent behavior gives children a sense of security. They need not spend all their energy figuring out what parents are going to do next. If rules are consistent, results of disobeying them will be predictable.
Enforcement is important.
The importance of a rule is learned by consistently having it enforced. A child who is disciplined for throwing the ball in the living room on Monday, but not disciplined for the same action on Tuesday, is confused. This confusion results in children not understanding the reason for rules or principles. Consistent enforcement of rules tells the child that rules are important. Consistency between Parents Set common rules.
