When your child treats you disrespectfully, how does that make you feel? Do you want it to continue? if not, think about making some changes iin how you relate to your child.
First of all, you are the parent and should be the one in control, not the child. If your child upsets you, you've given control over to your child. In order to get it back, place the units of concern on your child by using natural consequences.
For every disrespectful statement coming out of your child's moputh, tell him or her she's just let you know he or she wants to do an extra chore to help you around the house. Then, give a choice between 2 chores and then give a choice between two times they can do it. The next time your child wants you to do something for him or her, smile and say, "I would be happy to do that as soon as you......." This could be
1. Treat me with respect
2. Do your chores on time
3. Whatever else you want your child to do.
Do NOT engage in a conversation or discussion about this; other wise you've just been sucked into the unconscious game I shared with you on 8-09-05.
