My daughter went to the Children's Courtyard in Lewisville on Round grove road, and willow ridge. By the time she was 2.5 she could write her letters, spell her name, and knew words like imaginary and creative, and what they meant and could apply them to sentences. I loved the curiculum they used and was thrilled with all her teachers. They have a very low turn over rate. Casey is the preschool director and she is wonderful. There telephone number is ###-###-####. I know you asked for Flower Mound, but it is seriously the best of all the courtyards that we looked at and, after we moved from Lewisville to Denton, I still drove my daughter there for daycare. They are open from 630-630 and are great and flexible and just wonderful, we had such a good expirence we still send her back for summer breaks, (she is in 1st grade, and we are home now when she gets home from school.)
Good Luck.
