There's a few of us that live in the general LA/OC/IE area, but I think we're all pretty spread out.

You may want to look into a local La Leche meeting, theres usually quite a few AP moms at the meetings. There's meetings in Glendale and Pasadena.

There's also a LA based babywearing group on Yahoo groups, I'll PM you the link to that, and they may know of a AP yahoo group in LA - There's one for OC and IE, so there should be one too..They'll usually have playgroups and other outings going on.
