Hi K.,
I am one of the founders of www.BurbMom.net for this very reason. I had a large online support community but it was all over the world. I wanted to find other people who were local to Dallas-Fort Worth. All of the people who write stories for Burb Mom are from DFW.
If you are looking for a moms group, here is a list we compiled: http://www.burbmom.net/moms-groups-dallas-fort-worth-metr...
If you are looking for some things to do with your child, here is a list of some of the local attractions we have written about: http://www.burbmom.net/family-activities-things-to-do-in-...
We try to publish new things related to North Texas about 3 times a day so there is usually something new to read.
So glad you are moving here. I have been here for 8 years and really love it. It is truly home. Feel free to contact me directly if you have any questions!
