Hi W.,
Congratulations!
Are you interested in joining a new mom support group? It was a great way to meet other moms of new babies in my neighborhood (Washington Heights).
You can check out Jessica Shapley's groups -- I believe she also offers a group in Riverdale.

There are also often groups though the neighborhood Ys.
Good luck.
