I just show up at the same place week after week. Saturday we do a farmers market, thursday a park, Friday the library. Someone will talk to you eventually :)
Look into the MomWalkCo, on social media. They have groups everywhere!
Look for a MOMCO in your area! This has been a wonderful way to meet other moms in similar life stages! https://www.themom.co/find-a-meetup
Hey! I’m also from SoCal, Ramona to be precise, and I’ve been lucky meeting moms at the local parks. It’s a good place to go meet another moms with kids around the same age ☺️
