mom groups?

I live in Orange County ca and I'm looking for mom groups to meet with. I'm struggling a little. My baby boy is 18days old and I'm starting to feel like I have no idea what I'm doing because I still cannot figure out what he wants. He gets bad gas and I can't figure out how to get rid of it. I think it would be nice to have a group to talk to and have grown up interactions with. Let me know if anyone is interested in play dates.
