Hi L.,
I live in the Falconhead development. I have taken my daughter to My Time Kids http://www.mytimekids.com/ in the past. I moved away for a year and just returned. During that year, we went to a local My Gym and loved it. I wish one was closer to our area now, but the closest one is off Lamar/Ben White area. You can check out a free class at My Time Kids. Lorie is the owner and she is wonderful.
We also belong to a the local Mom's group http://www.meetup.com/Bee-Cave-Lakeway-mom-meetup/ They have a variety of activities all the time. We are a very active group.
Welcome to Austin and take care,
V.
