hi kappachi!
I'm in Tucson, too.

I have a little boy who is 2 1/2, and a baby girl who's almost 3 months.
There is a "Tucson playgroup" thread in the Utah/Arizona tribe (go to Finding Your Tribe>Tribal Areas). we use to organize a lot of get togethers but there hasn't been much happening on the thread lately... I think because a lot of us that used to post a lot had new babies and life got pretty hectic.
I'm also in an Attachment Parenting Meetup Group-- really nice people in that group.
I'm in a few other playgroups in Tucson--mostly mamas who homebirthed, etc. Feel free to send me a private message if you want more information about anything!
