We also open ornaments on Christmas Eve. This year, we'll be joining an odd tradtion on DH's side of the family, which includes Santa visiting DH's uncle's house to personally deliver a gift to him. DH's aunt and uncle started doing it when they got grandkids and have continued doing it for their grandkids' kids and the cousins' kids. Santa even comes with his own elf to help out.
It sounds sweet, but there are usually babies screaming, the one child is autistic, so he's stemming around the living room, and his twin sister is terrified of Santa, so she's hiding in a closet screaming as well. I can't wait for Micah to join this joyous tradition. Pass the eggnog and mimosas.
