Any Moms groups that focus on high-brow activities for the Moms, but allow babies to be included?

As a business exec that now stays home with my baby, I am looking for any groups like this that exist or to just start one b/c as fun as the playground is I also want to continue discussions of politics / business with other moms, financial seminars since I now have time to audit / manage all of our investments / bills and a museum tour or high-level class every now and then — there must be a way to attend these things and build teh babies into it too — SUGGESTIONS? thanks!
