Well, I can't really help you on finding people your age, but I do have a suggestion for meeting friends. I am a part of MOMS Club and I highly recommend it. There are weekly activities for the kids in addition to playgroups and monthly Mom's Night Out. You can attend as much or little as you're interested in. I know SO much more about fun things to do with kids in our area than I even had any idea existed before. And it's just nice to have a social outlet for both me and the kids and a support network. They brought me meals for 2 weeks when I had my daughter. It's very regional, so everyone in my chapter lives very near to me, which is convenient. To find a chapter near you go to www.momsclub.org My chapter only costs $23/year
As far as the age thing goes, I'm the youngest member of my MOMS Club, but we still enjoy each other's company. I'm 26 now, but I also got married young--I was 19--and I am very happily married to a wonderful man. Enjoy the ride!
