What Happened to Jacob?

Jacob was whiny last night and upset and squirmy for a few hours. Finally I fed him and put him happily in his bed at about 1:00 am. I woke up at 6:17 am and wondered where Jacob was. I hadn't heard him at all through the night, but sometimes that happens. Brian never sleeps well so if he's already up, he'll grab Jacob and give him a bottle so I can sleep. I know, he's a keeper. But, he didn't do the bottle thing last night. Jacob actually slept over 5 hours! What a good night!
