After taking a spin around the new Brookfield Place ice rink, head to this (totally free) fest for crafts, performances, a concert and treats a-plenty. Join DIY organization ScrapKins, who'll lead a workshop where tots can build their own sleigh ships and sail them down an ice flume. Then, take in a 15-minute rendition of A Christmas Carol by the New York Classical Theatre, plus a high-energy show with Metropolitan Klezmer. Once they've had a romp inside the igloo playhouse, little ones can warm up with hot chocolate from Mud and One Girl Cookies. All ages.
