We have twins. They were born split at midnight (the year of the millennium!) Which is really convenient because whatever year it is—is how old they are! We have a tradition that actually started for me back in college at the University of Dayton. My sorority has a tradition for new initiates called a cookie shine. Basically a room full of sweets laid out and all the new pledges get to fill up bags of goodies—on the count of 3! So fun!
I took that idea and decided to apply it to my kids birthdays. After they go to sleep we decorate the hallway and door with their favorite treats.
