New to to the area with my almost 4yr old. Looking for recommendations for play based preschool for my DC. A Welcoming school with caring teachers and kids are most important as this will be the first school my DC wil attend. He was some with me until now. He is very bright but is a bit shy and more of a quiet and reserved personality (not high energy). Anywhere in Fairfax country would be fine for recs. We live next door to Merrifield mosaic area. Thanks in advance!
