Copley Plaza - In nice weather, head over to Copley Plaza, bring your lunch dip your toes in the fountain. Toddlers can crawl all over the tortoise and hare bronze statues (a tribute to the runners in the Boston Marathon). May to November, Tuesdays and Fridays, there's a large farmers market where you can buy snacks and picnic supplies.

Children's Library, Boston Public Library - Make a beeline for the children's reading room. Along with a super collection of books for kids, there's also an area for little ones with coloring, puzzles, short tables and chairs. On bad weather days in Boston, this room is an island of color and imagination.
