things that mark the passage of time

Last night I was watching Nahshon jump around on the couch like a little monkey, wearing Thomas the Train pajama pants. As I was watching him I realized those are the pajama pants Isaac used to jump around the couch in, and Nahshon was still nestled in my tummy. It's hard to believe Isaac was once that small, and even harder to believe that at this time next year Micaiah could very well be jumping around in those same pants. It goes so fast, and I'm so glad I get to savor every moment of it.
