Wow, I'm pretty excited about finding this group!
I'm 21 (just turned on Oct 1), and DH will be 24 next week. We've been married for 2.5 years.
DD is 14 months, so I was 19 when I had her.
Re: friends, I really don't talk to any of my friends from highschool, etc... First of all, we moved 700 miles away from our home town right before we got pg. Then I had DD and I just don't think any of my former friends "get it". They don't get that she's the most important and exciting thing in my life -- I guess the feeling's mutual, they don't particulary enjoy me rambling on about dd and I can't stand listening about the partying, etc that they're doing.
It's really ok with me though. I've made some great friends here with kiddos about my dd's age (though they're all about 10 years older than me...). I just wish they were more AP.
Nice to "meet" you all!
