I'm in Fremont too! My SIL is in Livermore so I travel between those areas. There is a fremont group on meetup.com but I've never been able to go because the dates always conflict with something else.
I've had luck connecting with East Bay mamas on Parenthoods. They had some really cool events near the end of the year. And the discussion feed shows other families near you and what they're talking about. It's a free iPhone app. parenthoods.com/app
