This is funny, because I'm always trying to set you up with my friends! Sadly, they keep pairing off before I can get them to you.
Barring my future as a matchmaker, I met my DP at a queer grad student social. But, we started dating before I had a baby, which makes doing things like going to socials more complicated. I second both online and church. I've totally been caught cruising people at our old Unitarian church. (And the Unitarians are so easy to join- you don't even have to believe in god!) And there's usually free childcare, which is nice when the baby is old enough that you're ready for a break from her for an hour.
Other places I've met partners: bookgroups, craigslist, the gay nude beach, and of course, through friends...
Also, I totally get cruised as a parent all.the.time. It's actually sort of fascinating to me. It's usually by cisgendered men, so they do assume I'm straight, but apparently they don't assume I'm married! And occasionally, it's by a really hot woman.;) So, having a baby does not automatically make you appear off limits, it turns out.
