Children eleven and under ride the MBTA free, with no cap per adult, which makes a Boston day cheaper than the same day in Washington or San Francisco. The catch is the closed day: the Children's Museum and the Museum of Fine Arts shut Tuesdays, the ICA Mondays. The Museum of Science opens daily.

The MBTA's rule is short and generous — children age 11 and under ride free, rail and bus, with no limit on how many ride with one adult. From twelve everyone pays a flat fare, so a trip out to Franklin Park Zoo costs the same as one stop down the Green Line.
Boston's major museums close on days you would not guess, and not the same days. A Tuesday with young children is a Museum of Science day, an ICA day or an outdoors day.
A surprising amount of the city costs nothing at all: no pass, no timed entry, no reservation. These five are free every day they are open.
A landmark reading room open to anyone, with free art and architecture tours and a courtyard that is the best free sit-down in the Back Bay.

Two indoor attractions are the expensive part of a Boston day. Both have a catch beyond the sticker price.
Pick one indoor anchor and do it in the morning, when the queues are shortest and the child is fresh. Make the afternoon free and outdoors.
