I love the fact that when Callan is in a good mood I can put him down in his crib for a little while, with mobile on, to get a few things done around the condo. The mobile totally mesmerizes him - it's fantastic. My one complaint is that it only runs for a few minutes (like every other mobile), so I'm constantly having to run in there to wind it back up, otherwise he lets me know that it has stopped. At one point yesterday, I snuck into his room to take a quick peek at my favorite little man and found him gazing away at the 4 little birds twirling over his head. He was so content and looked so cute, I had to grab the camera.
