I think preschool is a better option than just a babysitter if you work full time and need somebody to watch your kids, because at leasrt it is educational. But if you are good parents and enjoy teaching your children when you are with them, then keep them with you as long as possible. People put little value on the time they spend with their children, and then wonder why they don't respect them later when they are sneaking out their window at night. Spend as much time with your children as possible, become part of their development before the State mandates you hand them over.
