Does it have to be a SAHM only group or a meet up group? Depends on where you live, but I'd check out CharlotteMommies.com (or Union County Mommies, Lake Norman Mommies, York County Mommies depending on if you are somewhere in the outskirts of Charlotte). They have lots of events and forums so you can get to know people online too. That was great for me at first because I was too afraid to leave the house with a newborn!
