I know too many people who let their children decide what they are going to read or if they are going to read. This is the same as letting them decide what they are going to eat. No child is going to make good choices. They are going to go for the comic books and the candy. That is why you are their parent. You are there to direct and guide them.
Just like a potter with a lump of clay, the potter shapes it and molds it until it is tall enough and strong enough that it will be useful. It has to be shaped in such a way that it can endure the heat of the kiln and the wear and tear of use.
Children have to be shaped so that they can be strong too. They need to be shaped so that that are good people and helpful and kind. They need to be shaped so that they can survive out in the world and not crack.
So in the same way that you wouldn’t let a child pick out all of his food when he is only going to go for cake and chips, you can’t let him pick out his books when he is only picking out what is essentially junk food for the mind.
Now we all need a little junk food reading every now and then. It is important to let kids have some control over what they select. They need to learn that reading is a pleasure and not a punishment. They need to feel that it is fun and not work. But a solid diet of junk food results in a sick body. A solid diet of junk food reading results in a sick mind.
If you let children have total control that is the same as the potter letting the clay have control. They will be an unformed lump at best. They will be spread all over the place at worst.
Don’t know what to recommend to your child? Go to your local library and ask a librarian. They are there to help. You don’t have to do this on your own, but you do have to do this. The mind you save will be your child’s. The world you will save will be your own.
