Here is an excellent blog post entitled, "Freshening the Homeschool Plan". It is for homeschooling moms of older children.
A plan and purpose to child rearing combined with the thrill of quality books and a deepening interest in history and science creates a momentum in the home that few outside the homeschooling movement really grasp. That momentum sustains many families for years, often right through junior high for the oldest child.
Lots of great ideas, including getting back out of the house, keeping up Mom's hobbies, and finding big-kid projects for parents and teens to do together.
