I've lived in Plainfield, the south end, for 5 years now and sent both my children to the Minooka United Methodist Preschool. It's only 15 minutes away, so not too bad of a drive. Their 4 year old program is only $140/month for 3 days a week, with both morning and afternoon options. They also offer a 3 year old program 2 days a week - jI forget the cost. You can find their number in the phone book. Hope this helps!
