L.P.
My boys (now 12 and 10) went to the preschool affiliated with my church, Pilgrim Lutheran Preschool. We were very happy and I know many others who have been as well. All the teachers are very caring and attentive and my kids had a great head start into elementary school. It is located off Meridian just north of I465. They attend from 9 - 12:30 (I think) but have an "extended day" option until around 2:00. As of last week they had openings for 2 year olds. I'm not sure about 4 yr olds but it's definitely worth a phone call. Good luck!
