I am reading through a wonderful book right now by John S. C. Abott entitled, "The Mother at Home." It is a wonderful book, full of timely advice from a Biblical perspective. Here is just one quote from the book.
"She (the mother) must learn to control herself; to subdue her own passions; she must set her children an example of meekness and of equanimity, or she must reasonably expect that all her efforts to control their passions will be ineffectual. A child gets irritated and strikes his sister; and the mother gets irritated and whips the chid. Now, both mother and child have been guilty of precisely the same crime. They have both been angry, and both in anger have struck another. And what is the effect of this sinful punishment? It may make the child afraid to strike his sister again but will it teach that child that he has done wrong that it is wicked to be angry? Can it have any salutary effect upon his heart? He sees this his mother is irritated, and thus is he taught that it it proper for him to be angry...This self-control, at all times, and under all circumstances, is one of the most important and most difficult things to be acquired."
