RE: How often do you get together with other moms/dads/babies?
Golly, I don't think I could function without a fix 2-3 times a week! My playgroup meets once a week (Friday in the am). I also usually do a mommy&me type thing with the local park&rec once week. And then I have a couple mommy friends with kiddos about the same age that I lunch with maybe once a week.
I've done library story times and things like that occasionally too when we were "between classes", etc.
HTH,
Beth, mom to older DD (8/01) and younger DD (10/06) and always missing Leah (4/22 - 5/1/05)
