PACE stands for Parent and Community Education. It's a new moms group that I participated in when Michael was born. Many of the women I met through my group I am still friends with today.
The organization pairs up 10 or 11 new moms (who all live in the same general area) with a trained facilitator for a 6 or 8 week discussion group.
You're supposed to sign up before the baby is born--so you can be assigned a group to begin 3 weeks post-partum. Contact information is on their site: http://www.pacemoms.org/.
It's about $250, but money WELL spent!
