As a few people have already stated, the local libraries have great programs for toddlers, including story time and craft times. Baker Books in Dartmouth has a story/craft morning as does Partner's Store in Westport. Southcoast YMCA, which has branches in Fall River, New Bedford, and Wareham, have great little kid programs, including play groups, swimming, sports, yoga, gymnastics, dance, crafts, and more. There is a Gymboree in Swansea. Southcoast Music Together has a lot of great programs in the area. The Providence Children's Museum is great (and you get free passes from your local library). It is worth the drive to Providence (plus they can fall asleep on the drive home). Speaking of which, check out the other neat places that the libraries can give you free passes to. Good luck!
