Welcome to the White Rock Lake area. There are many childcare options in this area. It really depends on what your needs are. Do you need full time or part time child care? Full days or half days? If you work outside the home, where is your office? I live near the Arboretum and I teach early childhood music and movement classes at several area childcare centers, including several mother's day out facilities.
White Rock United Methodist Church Discovery Center is one of my favorites. Unfortunately, they only operate 9am to 2pm Mon-Thurs during school year and are closed for summer break.
Wilshire Baptist Church on Abrams at Mockingbird has a good PDO program, but they usually have a waiting list.
I have always used Dallas Day School because my oldest daughter was there as an infant when I used to work near downtown. They are located off Haskell Avenue across from Cityplace. Their hours are 7am to 6pm Mon-Fri.
There is another place called the Children's Center that is only half days till noon or so. I cannot recommend it, however, because I've never used them and don't do any classes there.
Good luck.
