Not sure how that happened when he was just born a couple of years ago!
Seriously, it has not been 5 1/2 years since he was born, right?! A year ago, I remember thinking that there was no way he'd be ready for Kindergarten in a year, he had a lot of maturing to do. And I would venture to say he still isn't terribly mature, I still can't believe he will be able to survive in school all day long for 5 days a week, but he will. He's ready!
We're not ready, but he is!
