Its the most wonderful time of the year!

Tomorrow is the first day of school! Yay! I've been looking forward to this!
The backpacks are packed, the first day of school clothes are set to the side- but where is that other shoe???
Why is it that one shoe constantly goes missing- and as soon as you find it- the one you had in the first place is gone! I hate shoe hunting.
So as I hunt for Connor's missing shoe- and hope that Sadie's shoes are in the same place I put them last week- I try to avoid the thought that I have a first and third grader! Next year this time I'll be packing Grace up for her first day of Kindergarten, sending Connor to Second grade and Sadie to Fourth! Where has the time gone???
