You might also check to see if there is a MOMS Club near you. That is what I joined when I started staying at home and it's the best thing I ever did. I'm in Coppell and we have two great groups that include Coppell and Valley Ranch. It's a national organization with lots of rules but they also limit your liability regarding having folks in your personal home. I know there are other area groups but I don't know all of them, you can check at momsclub.org. The Coppell chapters are both at ____@____.com. A group like this offers not only playdates but small meetings with speakers, moms nights out, park outings, meals for new moms/families, and a ton of support!
I do know folks who have made friends/playdates at the library storytimes for kids. I know Coppell and Valley Ranch both have good baby ones.
Good luck, it definitely helps having a support group!!!
