I'm going to come out and say it:
It stinks making plans with other mothers of young kids.
They are never free. It's either date night or a soccer game or a kids birthday party. And if I do manage to make plans with one of my mom friends for a playdate or girls night out, there's a 50/50 shot that someone will start throwing up and it will get canceled.
I used to think it was just me. That my friends were particularly unreliable or they didn't think I was fun enough to make time for. Then I joined the Facebook group for my town, and it opened my eyes. Women will make a post saying they are desperate to make friends and they will set up a playdate for a bunch of kids at the park. Then the very woman who complained she didn't have any friends will flake and say she can't make the playdate!
I had a conversation with the woman who started the Facebook group. She told me she organized an event for the moms in the group, multiple people RSVP'd, she reserved a location, and then she was the only person to show up. I told her the same thing happened to me when I tried to organize a book club for the moms.
It honestly makes me want to just have friends who don't have kids.
