We introduced Natalie to the concept of half birthday's this year. It's a tradition that my family practiced when I was growing up because a whole year is an awful long time to wait when you're a kid. We celebrated with a Skinny Cow ice cream sandwich (I called it an ice cream cake...) and a new Play-doh set. And now she proudly announces that she's 3 and a HALF.
Such a fun tradition to re-live with them as I've stopped really celebrating my own half birthdays! Something about 31 and a half just doesn't seem quite as special.
