Hi A.!

They have meetups kind of all over, and they're fun groups. There are some more specific ones as well:

If you are interested in Green Parenting as well, there is a really great and active parenting group that has it's own website. http://www.portlandgreenparenting.com
Congratulations on your first baby! I know it's excited and scary at the same time. It's so great, though! My daughter is 17 months now, and it's been a trip! I wish that I knew all the stuff I know now before she was born, but that's how it goes! Feel free to email me if you have any questions about the groups or want to hang out! :)
