Have you looked into Facebook groups as other posters have suggested? Also, look into your local libraries. They usually have story time for infants, that would be a good way to meet other moms
I would try just getting out. A lot of gyms and community centers have open time for infants and toddlers. It can even be great just to get out to some of the parks, even small community parks. If none of that works for you, try branching out. Look for volunteer opportunites or hobby groups where you can get out around people non baby related.
