In the middle of the night...

For the last 2 nights I have been awoken in the middle of the night from music playing in the nursery. We put a little "fish tank" on G's crib. He is starting to roll around (not completely over yet). He keeps hitting the play button on the "tank" and the music plays and the fish swims. It is really kind of funny even at 3:30am. I can't help to smile about it as I go up the stairs to turn it off.
