If we have something exciting planned for a certain day, my DD often wakes up VERY early!
For example, the have #1 day at school about 1x a month (the child brings in the snack and does show & tell etc). My DD was up well over an hour early! Today we are going camping and the same thing happened. She also did this when it was #100th day of school (she was so excited for that!).
I remember getting up early for Christmas as a kid.. haha like 5 am.. but it is funny how DD is like this for so many things. Anyone else's DC?
