Hi A. -
My kids aren't quite the same age as yours, but I wanted to share a website with you that has been quite helpful to me: matchingmoms.org
It has listings of different moms and you can search by age of children, distance from you, etc. They also have listings of playgroups.
I think they may be having network problems at present, but they're working on them, so I would check back in a day or two. Good luck!
