Obedience.

Prompt obedience should always be demanded of a child, and the spirit of murmuring and questioning firmly repressed. None can command except they have first learned to obey.

Do not allow children to tease, nor, having once refused on good and sufficient ground, suffer your consent to be gained by siege. Make your refusal final, but do not refuse thoughtlessly, or for mere caprice. The wishes of a child are as real to him as those of grown people are to them.
