Is It The Swing?

As per usual, Paige was fussy at 11:00 PM. After a little comforting, she fell asleep and I put her in the swing. I went to put my head down on the couch next to her. The next thing I know, I awaken to the sound of her squeaking (she makes these sounds before a full-on cry), and the clock says 4:44 AM. That's the longest stretch she's gone without crying. I changed her extremely soaked diaper and fed her previously pumped breast milk, then I went upstairs to put her in the bassinet next to our bed. Megan later woke up to change and feed her, and to her surprise it was around 8 AM. By far it was the first full nights sleep my wife has had since May 5th. Was it the swing? I always play my iTunes library to comfort Paige, and she slept through about 79 songs. Maybe she's learned to be comforted by music. Or maybe she's bored by indie rock.
