K.B.
For the past 3 years, one or more of my kids have attended Little Hands Preschool (http://fupcdc.org/preschool.asp) and another one I've heard good things about is Good Shepherd Lutheran Playschool (http://www.goodshepherdlutheran.us/play_school.htm).
I have friends whose children attend Cloverdale School (http://www.cloverdaleschool.org/), and also St. Francis in Triangle (http://www.stfas.org/)
There is a new childcare/preschool facility opening on Rt 1, close to you, that looks wonderful: Creme de la Creme (http://www.cremedelacreme.com)
Now is the time to register. Most preschools begin open registration & lottery drawings in late Jan./early Feb. Good luck with choosing the best one for your family.
