This problem most often manifests itself in boys between the ages of 9 and 12 and may extend on indefinitely if something isn't done to put it to an immediate halt. You can chalk it up to entering adolescence if you like, but hormone surges are no excuse at all for being disrespectful to one's mother.
All three of our sons went through a time when they were disrespectful in their manner toward me. (I suppose daughters can be this way, too, but I don't recall Lydia having this problem much.) What really helped was Dad getting involved.
I chose a time when Hubby and I were alone together and discussed with him the conduct of whichever child was acting out. First of all, I asked him if he thought it was appropriate for the child to treat me in such a manner. He agreed, of course, that it was not. Next, I asked if he would partner with me to bring said child to repentance.
We then got the child alone, and Dad firmly let him know this type of behavior would no longer be tolerated. Zero (-0-) tolerance. In the future, if Mom corrected his behavior and he refused to repent, she would be reporting him to Dad who would mete out judgment later in the day. (Of course, I didn't greet Dad at the door with this. I usually waited until after dinner when the time was right.)
After this meeting, when they started mouthing off to me, I would stop the car or stop whatever was going on and give them my full attention. Then, I would tell them in a quiet and controlled manner that they were disobeying God by not honoring me as their mother. There was an acceptable and an unacceptable way of speaking to me. If they didn't repent immediately, I would have to report their conduct to Dad. If they repented, fine. However, repentance included
- a right attitude
- a right tone of voice
- and even a right facial expression
Once Les spanked our sons for their unrepentant disrespect for me, their whole attitude changed toward me. I believe that is the main reason the boys and I now enjoy the fruits of healthy mother-son relationships. It is important, also, for them to understand that they have not only sinned against their mother, but against God who commanded them to honor their mother. Therefore, the boys were taught to call upon the Lord regarding their sin of disrespecting their mother. Leading the children to memorize Scripture regarding this command are also helpful in leading them to recognize their guilt before God.
If you are having problems with your children disrespecting you, I encourage you to take the motherly dominion God has given you to train your children in the fear of God and begin today to lay the foundation of future peace and sweet fellowship.
