My wife and I decided to start a new tradition this year. We bought this and filled it with little papers describing activities we can do as a family.
Growing up, my parents gave me those chocolate advent calendars , and I struggled hourly to keep from eating all 25 in one sitting.
So far, we've loved all the activities. Since our daughter's attention span is about the same as a Chihuahua hopped up on Mountain Dew, none of our activities are elaborate, but she seems to like them too.
However, her favorite part is opening the little doors each day.
