We took him down to the science center for the afternoon. He loved the dinosaurs and hands-on experiments. Shortly after we got there though, little guy was running to fast, and tripped and hit his lower lip right on the edge of the first step. Broke it wide open, enough blood to make me really worried, but I did my best not to let him see me freak. He took it fine, we cleaned him up and took him to the planetarium. I want to take him back in a few years when he can really appreciate it more. Either way, I am happy we took him.
