Reading through this:

During one of our trips, we visited a family which lived a very simple life in a very modest home, and homeschooled their five small children. The parents were quite soft spoken and gentle in manner, always speaking to the children in a calm, quiet way. From the very beginning of our visit, it became obvious that the children “attended” to the voices of their parents. The parents had first time obedience from even the youngest, and this obedience was obtained with a quiet voice and manner. In all my life, I have never witnessed anything like it. On one occasion, the one year old began to climb up on the kerosene heater. I saw the father give an almost imperceptible shake of the head and heard him say in a whisper, “Isaac, huh, uh.” Immediately the child shifted into reverse and backed away from the heater. The child attended to and obeyed the very whisper of his father. It moves me to tears to recall that scene and the affection which the children and parents had for each other. Oh, that I had trained my children so well when they were young. God wants first time obedience from us, and we should form the same habit in our children. When we resort to speaking in a loud voice when we want something of our children, or when we form the habit of repeating our requests, we train our children to ignore us when we speak. If we could only begin at the very beginning to train our children to attend to our voice — to listen for it no matter what they are doing, and to immediately obey, how well we will prepare them to listen to their heavenly father as well.
