I'm having one of those moments...

When you get kind of sad that your baby is growing up so fast. Jasper is 4. He's at such an incredibly fun age - curious, inquisitive, devouring facts and information, active, playful, etc. We had a conversation on the way home from nature school about cells. He started listing off all the things that are made out of cells. He got to car tires and said "Yes, mom. Car tires are made out of cells because they are made from rubber and rubber comes from the bark of trees and tree bark is made out of cells." What??!!! I don't remember teaching him that. That must have been his father, the cell specialist. I complimented him on the way he used his brain and worked through a problem and found an answer. I didn't want to say "YOU ARE SO SMART!" because the books tell you to avoid telling your kid they are smart over and over. Anyway, my point is, he is growing up and I feel like it's flying by faster than I'd like. So, I am indulging myself and looking through old photos of him:
