The following discipline techniques can help you effectively discipline your kids:

• Use distraction to get your child's attention away from inappropriate behaviors.
• Stop inappropriate behaviors with a firm ‘no' while looking your child in the eyes.
• Physically move your child when he is misbehaving, especially if he didn't respond to your firm ‘no.'
• Use extinction to remove attention from undesirable actions. As long as your child can't
  hurt himself, you can walk away and not give him attention or an audience for acting inappropriately, especially if he is having a temper tantrum. Giving too much attention to your child when he misbehaves can reinforce bad behaviors.
• Use natural consequences (rewards) to let your child learn the results or consequences of his actions. For example, if he throws a toy out the window, then he can't play with it anymore.
• Use logical consequences (rewards), for example, if he doesn't put away his bike, then you will do it, but he won't be able to ride it for the rest of the day. For older children, not filling the car with gas can have the consequence of not getting to use the car this week, etc.
• Use time-out to remove positive reinforcement or attention when he misbehaves.
• Withholding privileges is a very effective discipline technique, especially for older children. Find things that he likes or especially enjoys (playing video games, renting movies, going to the mall, talking on the phone), and then take it away as a consequence for misbehaving.
