I just posted this on another thread, but I am in two wonderful groups that I absolutely love! The Carrollton group is smaller, but obviously closer to home. http://groups.yahoo.com/group/CarrolltonMoms/
As Kristy also mentioned Meetup.com has some good groups. I have been in the Collin County group for about a year now and made some good friends. http://newparents.meetup.com/220/ It is worth the extra drive for this group because they are so active, there is always something to do.
Both groups have babies from 0 to about 2.
