I was always worried about my daughter (19 months) being too shy. Early on, I joined our local mom's club and a group run by one of our hospital's lactation consultants. Have you looked into a mom's club. I don't know about the other groups, but Bethel has a lot of great activities every month. You can look into joining your local chapter via the following: http://www.momsclub.org
Also, have you looked at indoor play facilities like Playtime Village in Monroe or Top Flight? Even your nearest library may have some fun activities.
