For those of you who asked what MOMS Club is:
https://momsclub.org
There are chapters based on territories broken down by school zones.
I've been in MOMS Club for the past 2 years and can't say I have really bonded with anyone in the club. There are definitely those who hang out more than others, the same moms who always go to the same events, etc. I also don't try that hard to connect with them because to connect with them, you usually have to go to almost every thing they put on the calendar. So it is partly my fault. The best way I have found to break into this group is to join one of their age-based playgroups because then you're on the same schedule with the same group and can build a rapport.
