One year. It goes by fast, but sometimes seems slow. I don't see them changing much, until I look back at a picture from a year ago. Then I realize how little they were and how big they are. Then I think about how next year, I'll see they are so much bigger and how little they looked this year.
I needed this today, after an especially tough 2 days with Bo (the whining, disobedience, etc.). He's growing so fast (especially his foot!!).
