The Zoo Lights at the Stoneham Zoo are wicked cute! They even have an exhibit where you can take your child's picture with a baby reindeer. Its $7 to enter and babies are free. I would recommend dressing warmly, bringing blankets, and trying to go on a warmer night. There are lights everywhere! Babies and children of all ages really seem to love it.
