Finding "mom" friends?

So I've really never had a lot of friend. The few that I've had that I considered to be close, I feel we've now out grown eachother 😔... I'm expecting my first baby soon.. I've always imagined our kids growing up together but it's like we are all at such different stages in our lives. We aren't as close as we thought we were or use to be. It kind of hurt my feelings but I get it's a part of growing up and becoming an adult. Not everyone is meant to stay in your life.

Just curious what are good ways to find "mom" friends (other moms that you can get advice from, have play dates, or mommy time with, ect). I know when kids start school that opens doors to meeting new mommies, but that's so far away lol.

I just want to be able to have someone to relate too when it comes to this mommy stuff. Someone who can give me advice. Understand some of my frustrations. Come over for drinks while the kids play. Plan little fun activities to do with them. Like I have my mom and my husband. They are great but I feel as new parent it would be nice to have a girlfriend that I can hang with that isnt in a completely different phase of life
