Train Whistles Update

I mentioned once before (HERE) about Abby listening to a train whistle and smiling when she was almost 4 months old. I thought then that she might enjoy hearing them as much as I do. It seems like just recently she has started noticing them again and will stop playing, smile, and run to the front window and wave. You can't see the tracks from our house, but I guess it's the thought that counts!
