Margaret Warner Morley, The Renewal of Life, How and When to Tell the Story to the Young, Chicago, A.C. McClurg & co., 1906.

This book notes in its introduction that any child old enough to ask a question is old enough to know the answer, the real answer, which I find enlightened for the period. Ms. Morley notes that parents only do their children harm by withholding truthful information and that it is best to give geared to age responses that the parent may elaborate on as the child matures.
