Aiden's First Day of School

Today we sent Aiden off to his first day of preschool! He will be going two half days a week at a church just a few blocks from Jason's work. I have mixed emotions, as I am not accustomed to being away from Aiden more then just a few hours but am looking forward to some one on one time with Alexander. Mostly, I cannot believe I have a child old enough to be attending preschool. How did that happen?
