Hi,
I am not sure where you live, but there are a variety of moms groups on www.meetup.com--I noticed that the Libertyville one is geared for women with younger babies, but they have meetings pretty much all over the Chicago area.
There is also something called Mothers and Company but I only know of a southside chapter in Beverly/Morgan Park: www.bapa.org/article.asp?articleid=305
There is also something called MOPS, but you should know that it is faith-based. Their website is www.mops.org/
Finally, I know of Family Focus--they have several centers all around the Chicago area. Their website is www.family-focus.org/about/index.htm My sister goes to the Highland Park drop in center, which provides a lot of support for her. They are flexible about payment and also offer a sliding scale arrangement.
Good luck. Let me know if I can be of further assistance,
C.
