Hey Little Dude,
You know, I used to write letters to "my dear sweet Baby A.J." That was a long time ago, back when you weren't quite so "active" and took much more reliable naps. These days your naps are few and far between and when you do finally crash, my quiet time is normally spent addressing the destruction left in your wake.
That is going to change today. Today you are going to school. You're going to have such an awesome time with your new friends and I know your teachers are going to have fun teaching you some really neat stuff and learning about what a cool little dude you are. It's going to be different for you to follow someone else's schedule instead of making your own routine, but it will be worth it.
It's going to be different for me too, being here without having my little shadow. It's a good thing I have a list of a million things to keep me busy until I can pick you up to hear all about your day! This is going to be good for both of us.
P.S.- Please don't eat anything that's going to make you itchy and sick, okay?
