Sleep Laugher

So, we've all heard of sleep walkers and sleep talkers. Tonight I witnessed something that I've never even heard of before...sleep laughing! Here's what happened...
Owen had been asleep for about 45 minutes when I took Quincy up to the boys' bedroom to put him to bed. He had finished nursing, and I was just leaning over to put his groggy little self in bed when suddenly all of the smoke alarms in our house started going off.
Noni Jo was downstairs preparing Milanese for tomorrow's feast, and the smoke alarms started going off. All of them. Seriously. Every single one...including all three upstairs, which are located in the boys' room, in the bonus room, and in the guest room. All three of the upstairs smoke alarms are located within 20 feet of Owen's bed. Why am I telling you this? Because throughout the cacophony that was ensuing in Owen's bedroom, he did not budge. Not an inch. My point? Only that he was deeply sound asleep.
About 15 minutes later, things were all calm again, and I was again in the boys' room attempting, for the second time now, to put Quincy to bed. I was swaying with Quincy in my arms and softly singing "Lady Moon" to him when I thought I heard a little giggle. Then it was silent. Then I definitely heard another little giggle very clearly coming from Owen's bed. Pretty soon he was chortling and then full on laughing. It was so funny that it was all I could do not to laugh out loud myself. I nuzzled my face into Quincy's blanket and tried to stifle my own giggles as I thought about children's laughter and how it is one of the things that I am so thankful for.
