I met a woman at Babies R Us a few months back and we got to talking and she invited me to a mom's group (I think she said that it used to meet at the hospital so maybe it was the same as the one below). Unfortunately, though we tried to call each other a couple times and get there, I never was able to go.
However, when I was at the library I saw a flyer for a Rockford Mom's group. I e-mailed them. I can't find my e-mail response but this is the address I contacted. ____@____.com I can't remember all the details of the kids ages and stuff but it was for sahms and there was a fee to join (maybe $20) but she also said that no one would be turned away for not being able to pay.
I would love to get out but I have a hard time getting it all coordinated between half-day pre-school schedules and all. We try to regularly go to books and buddies at the library and I just finished a session of the mom to mom group at Heartland. I know they are doing a workshop on May 2 called SummerDaze that I am going to go to. Here is a link to their website. http://www.heartland.cc/index.php/rockford I think you get to pick 2 workshops out of the 4. I can't remember all the descriptions. I know one was about free and low-cost area activities/vacations and at another you got to make a little scrapbook. I went to their winterdaze one and I liked it.
