Hi, just a slightly different perspective, but I didn't send any of my kids to pre-school at all. My eldest is now an honor student, already accepted at the college of her choice, and very sociably adept. My youngest started Kindergarten this fall (I know, huge age apread!), and he is far and away the best reader in his class, as well as excelling in math and science. I just don't think pre-school is absolutely necessary, especially if you can gear what you teach your kids towards the standards for Kindergarten. I kept my kids home with me because I knew I would never again have a chance to spend that much time with them, and I don't feel like they missed out on anything.
