Since I homeschooled my children, there are times parents have come to me to ask about homeschooling. The biggest advice I can give is to make sure their child(ren) learn to read well. Also, I encourage them to help their children enjoy reading. How? Don't give too much to read, give a challenge, but not too much, and also give them time to absorb (don't push too fast).
When you learn to read well, you can learn on your own for life. If they don't enjoy reading, they typically lose that love of learning, too.
