Yes, all the events are on the "Our Events" page at the top menu. All the events are open for all members (though some may be geared towards certain areas or demographics, like moms of 2). The groups are geared more towards discussions. Most events have moms from all different areas of OC.
Hi Laura - welcome to OC Mommies! Your little one is so cute! My guy is 10 months now, and I miss that teeny stage! I'm on the new member welcoming committee, so please feel free to ask me any questions you may have about the site or our events. I joined OC Mommies when my son was about 3 months old because I didn't know any other moms in the area, and I've met so many fun and welcoming mamas! Hope to meet you soon, and again, please don't hesitate to let me know if there's anything I can do to help introduce you to the site and our group!
