This is my mom group, and they are awesome. Unfortunately, most of them live in different states, which makes playdates difficult, so we spend a lot of time on email. Anyway, I’ve mentioned all of them before, but if you don’t know who they are, you should check out their super-genius sites — Eden is at Fussy, Heather is at Dooce, Melissa is at Suburban Bliss, and Alice is at Finslippy. They will rock you.
