I realize it's kind of late notice for you, but last week there was a similar post about meeting other mommies and four of us from the bump are getting together tonight for dinner. If you happen to be free and want to join us, send me an email at kari.l.wood at gmail.com and I'll send you the details.
As for meetups, I tried out one but it wasn't a good fit for me yet as an expecting FTM. Maybe after the baby is here and ready for playdates. I know others have good success though, so hopefully they'll post some recommendations for you!
Thanks for the invite. Let me know the next time you guys hang out, I would love to come.
