Here's the calm before the storm:
I gave each child a holiday-themed tin, marked with his/her name, and pre-filled with 1/2 dozen sugar cookies. Note for next year: 1 dozen! Each child got to decorate his/her cookies and/or eat them.
As everyone arrived, they split off into groups to play. The girls and The Girl got all dolled up from our dress-up bin, wearing fancy dresses + a pair of wings each. Some of them, like The Girl, kept this get-up on while they decorated cookies:
Afterwards, the boys went upstairs to play Lego and the girls and the tots stayed downstairs to watch 1969's Frosty the Snowman:
For my part, I got to drink spiked coffee and chit-chat with the moms about school, books, Boden, and other topics of interest.
