Dude LOVES trains

My sister gave us this train set a few years ago, and Lauren never really got into it. But, it resurfaced a few days ago and is an instant hit with Trevor. Last night we had to put the train set away, it was set up on his bedroom floor in a big figure 8, and he couldn't get to sleep... kept standing up and pointing to the set, saying 'train, train'. 'Train' was also the first word out of his mouth when I went into his room this morning.
