Hi C.! I don't know if it will meet all of your needs, but I am a member of a wonderful playgroup in the area. I live in The Colony, and the closest playgroup I could find with welcoming moms was "The Greater Lewisville Mothers & More" group. I have been a member for close to three months now, and I will tell you that it is a lot of fun for my child and myself. Lots of things to do, meetings for all types of moms and situations, field trips, etc. They are listed on the Local Business Reviews (if I remember correctly). Just a thought.
Good luck!!
C.
