La Berceau (The Cradle) by Berthe Morisot, 1872

It is not enough for parents to have a lofty ideal for their children, and to instruct and train those children in the direction of that ideal.  They must see to it that the atmosphere of their home is such as to foster and develop in their children those traits of character which their loftiest ideal embodies.  That atmosphere must be full of the pure oxygen of love to God and love to man.  It must be neither too hot in its intensity of social activities, nor too cold in its expressions of family affection, but balmy and refreshing in its uniform temperature of household living and being.  It must be gentle and peaceful in its manner and movement of sympathetic discourse.  All this it may be.  All this it ought to be.
H. Clay Trumbull, Hints on Child Training, 1890
