Sandra Bullock and son Louis Bardot hit up a Christmas party this weekend in Santa Barbara -- where Louis celebrated his very first holiday season with his adopted mother.
The adorable duo looked like they were having a blast at the bash, where Louis was spotted riding a pony while wearing a Santa hat.
Bullock first brought the New Orleans-born baby home in January.
