Try the play groups at the hospitals. Tuality Hospital in Hillsboro has a Free Support Group (the other area hospitals charge a fee!) for New Moms (and Dads) on Mondays, 11:30am - 1pm. This is for babies up to 12 mos and it doesn't matter if you delivered there or not.
I found a lot of support from other moms there who had babies around the same age. We compared notes, asked questions, and offered advice. You graduate to the Movers & Shakers group when your child turns 1 (or walks) until they turn 2. We formed our own play groups from there. I bonded with some great women there and we are all still friends as are our 2-3 yr olds!
That was the best advice a friend gave to me when I was pg. She lived in another town, but she said find a local hospital play group and GO. It's so valuable to meet and bond with other new moms, you won't believe you lasted this long without going!
Here's to you finding some other new mamas and babies!
