Racking up the firsts!

Corbin seems to be racking the milestones these days: from the first day of school to learning to ride a bike. Today he had two firsts.  First, he had his first play date which I didn't attend.  At his friend's house, he lost his first tooth. As I write this, the tooth and a letter to the tooth fairy at sitting under his pillow. 

It's exciting times.
