Laughing Himself to Sleep

Hudson is getting even better at going to sleep at night. We have definitely established a routine which involves diaper changing, pajamas, feeding, burping, a little rocking and then setting him down. The other night, when I set him down in his crib, he started laughing... I immediately thought that we had a long night ahead of us. Since he was laughing I decided to leave the dark room and see what happened -- he obviously wasnt upset. I brought the monitor downstairs and within 15 minutes he put himself to sleep. This may seem easy and simple but for a baby with imperfect sleeping habits, this is HUGE. By the way, the monitor is amazing...
