I'm using this post as a memo for some links I plan to read.
PR Article on Manners
Certain Relations Proper to a Child (Pages 82-90, CM Vol. 3 Ch. 8)
Misdirected Affections (Pages 58-63, CM Vol. 6 Ch. 3)
Faith and Duty: Parents as Teachers of Morals (Pages 101-116, CM Vol. 2 Ch. 11-- modern paraphrase)
(That one is very interesting to me. In it, CM reviews a progressive German author's attempt to inculcate moral teaching into modern 'education'. She goes with him a certain distance and no more. Her review shows how, although she embraced progressivism's improvements, she understood its limits and prejudices.)
