Mr. Jim Stenson, educator, author and speaker has many wonderful and practical articles on his website.

The following are links to articles on the Opus Dei website which pertain to Christian Life. They are an excellent resource for parents. 

...since parents have conferred life on their children, they have a most solemn obligation to educate their offspring. Hence, parents must be acknowledged as the first and foremost educators of their children. Their role as educators is so decisive that scarcely anything can compensate for their failure in it. For it devolves on parents to create a family atmosphere so animated with love and reverence for God and others that a well-rounded personal and social development will be fostered among the children. Hence, the family is the first school of those social virtues which every society needs.
— Pope Paul VI, Gravissimum educationis.
