Mommy and me

Hi I am in Contra Costa county and was wondering if anyone knows about mommie and me classes or meet ups? I sign up for a group, but they said they have too many members already. I'm a SAHM and would like to meet up with other moms and do activities together. Also meet new friends. I'm a FTM and don't have family out here. I have my hubby and a couple friends, but they're always busy. So if you know of any groups or classes please let me know. I'm in Martinez. Thanks😊
