3. Good behavior may need to be taught
Sometimes as grown-ups we forget children need to be explicitly taught how to do pretty much everything from brushing their teeth to politely responding to adults. If you want to change your child's behavior, you may need to show her exactly what you want her to do instead of assuming she knows the expected response.

Take a cue from your child's teacher and break the positive behavior into small steps for your child to practice. For example, if you want young kids to clean up a mess, you may have to show them step by step what needs to be done instead of just telling them to pick it all up and then getting upset when they don't.
