The Bible doesn't say that an undisciplined child brings shame to the father. No, rather, the Bible says in Proverb 29:15 that a child left undisciplined brings shame upon THE MOTHER! Mothers are supposed to spank and discipline the children.

You've probably heard the old saying, “You just wait until your father gets home.” I'm certainly not against such loyalty to fathers, but it would be better, I think, for the mother to learn to discipline her children when the father is not present. There's a science behind the disciplining of children, which every parent should learn about. There's a proper way to discipline a child. You mama's ought to be taking a switch to the exterior of your bratty child. Did you ever stop to realize that God put that padded area in the back for a reason? God made that padded area in the human posterior for spanking! Spank your child! Again, Dr. Jack Hyles explains in detail the proper way to spank a child in his timeless classic, HOW TO REAR CHILDREN.
