Sat. and Sun. Dec 9 & 10

For the kids and family. On Saturday Dec. 9, the Harvard Coop brings Santa and Mrs. Claus in from 11 a.m.-2 p.m. They'll hear wishes (not promise XBoxes) and tell stories (not about those Bad Santa movies) and warm the cockles of the heart, wherever they're located. Bonus: Kids get a free Polaroid photo taken with Santa. (There are places that charge for such items now.) At 2, the Harvard-Radcliffe Collegium Musicum Singers will perform traditional carols and jazzy holiday faves for an hour. The next day at 1 p.m., there's sing-alongs, puppet-making, crafts and the like for the kiddies, accompanied by the sounds of traditionally costumed Victorian carolers.
