I know of several mom's groups (Addy is only 3 months old) in our area and I just can't bring myself to go. I'm old, she's adopted, I'm divorced and remarried, I have older kids. I'm somewhere between feeling sorry for myself and Addy because we don't fit in and being so self righteous because we are such an enlightened family.
(both reasons are hideously warped). I think redhedded's advice is the best; join a class, start doing things with your daughter that you love and meet people that way.
Wish we were neighbors :-(
