There is a great free publication called Parent Wise: which lists various different activities (many free) for children of all ages. Try their link: http://www.parentwiseaustin.com/index.shtml
I just joined an attachment parenting group in South Austin that meets once a month. They also have play groups to attend in your area. That is something I found in ParentWise. LaLecheLeague has regular meetings as well. My daughter (17 months) and I go to The Little Gym and used to go to Gymboree. These are wonderful programs for mothers and babies. She & I actually started at Gymboree when she was just 3 months. I found it to be very helpful meeting new moms. Congrats on your new baby!
