Hi K., Both of my boys started preschool at age three. It has been the most wonderful confidence booster for them, they love the independence and so do I! It is only three hours a day three days a week. We are not at all religious and they go to a congregational church preschool in Phoenix. The religious aspect has never bothered me at all. It rarely comes up, and, if it does, my boys don't seem confused by it. I also think that knowing a little about different religious beliefs is kind of like a history lesson and they are bound to learn about it at some point anyway. I think 4 is a great age to start preschool - it will give your child a huge edge in Kindergarten! Good luck.
