what preschool curriculum do you use? My DH and I have decided that we want to homeschool our son for his preschool year. I need a curriculum that will include everything he needs to be able to start regular school next year. But I need something affordable, too. Grandma is going to help us out with the finances of it since my DH is laid off from work and he and I both are going back to school ourselves. All suggestions are appreciated.
