Use consequences appropriately.
Follow through with a consequence as soon as it’s clear your child hasn’t completed a task on time or in the way you agreed. The more you delay, the less likely your child will connect his behavior with the consequence.
Don’t go overboard. Taking away privileges for an entire week may be tempting, but prolonged consequences can lose their power and meaning.
Avoid being overly critical. Let the consequence do its job. It will remind your child what the reward might have been.
Use positive consequences, too. Try to “catch” your child being good. The positive attention may encourage repeat performances.
