It sounds so cliche, but I really do want to freeze their ages right now. At the very least, I pray that moments like these stay clear and vivid in my memory forever. One day they will be too old to be impressed about a train ride. My youngest (4yrs old) lives for anything that has to do with trains. His excitement was palpable, like a bubble ready to burst. He made my husband open the train window so he could shout "All Aboard!" Still innocent enough to be unashamed about his enthusiasm. It's precious.
