We are going through a major train phase. Ethan loves, and I mean really LOVES choo choos. We watch Polar Express about 5 times a day. Ethan calls it his "big choo choo" as opposed to the little Thomas the Train he constantly is holding. He even has Holland addicted. She wants to watch it as much as he does. I have to admit I like it too. I cried watching it the first time.
