haha, calling it a Mom's Club made me think of Fight Club, hehe
Seriously though, do you mean like a Mothers & More type group? My friend belongs to them and she loves it. There are weekly playgroups (by age) and then once a month meetings for the moms in the evenings where they have a guest speaker or some kind of topic of conversation. They also go out once a month for a Mom's Night Out.
I belong to the Mother's of Multiples and we have basically the same thing except we have a lot more events and activities for families because they make almost $20,000 per year off the yard sale so it affords us LOTS of fun things to do!!! Also, our Mom's Nights Out are fully paid, wohoo!
If the website looks fun, you should join. Many will let you check out a meeting for free to see if you like it, too.
Is MOMS Club different than moms groups?
I belong to 2 moms groups (through meetup.com). I just recently took over being the organizer (well, co-organizer actually...a friend and I are doing it together) of the one group because the old organizer got too busy and was going to let the group dissolve if no one took over.
I really like both of the groups for different reasons. But mostly because I've met a nice group of women, Ben has made some good 'friends' and I've actually become good friends with one of the women (the one I'm co-organizing the group with). We hang out at each other's houses with the kids, take them fun places, watch each other's kids if need be, etc. And it's nice because she's only 5 minutes away. With the other moms group, we have a standing Monday morning playgroup. It nice because the kids (since they see each other every week), seem to really have gotten comfortable and they play so well together. We've been doing this for about 9-10 months.
I joined my MOMs club as soon as DD was born. It has been good for me. In the beginning it was kind of rough because DD was the youngest by 18 months and we have a very small chapter. But almost all the moms in my group were pregnant with number 2 (seriously all but me and one other mom) so now DD is the oldest of the younger group of kids.
I think it is different from other playgroups because it is pretty organized and there is a governing set of rules that all members are supposed to abide by. So I think that helps keep away some of the cattiness.
