Who Says Moms Worry More?

So on most nights Sam will sleep in his crib (he's moved on from the box now) until the first time he wakes up, usually between 2:30 and 4:30.  After I finish feeding him I'm usually too lazy to take him back to the crib in the other room so I just put him next to me to sleep.  I always try to be careful that he's sleeping on his back and can't pull any sheets over his face.  I used to think since I was the one waking up at night that I was the only one worrying about him, but I'm learning that is not the case:

Last night Dave went to sleep around 11:00 while I put Sam to sleep.  It took me a while to fall asleep afterwards, and I read until about 12:40.  At about 12:30 Dave suddenly pushed up off his stomach, looked right at me and said, "I hope we don't squish Sam."  I laughed and explained that he wasn't even in the bed.  Dave kind of stared at me for a second, put his head down, and then back up again to look at me again.  He then tugged at the pillow behind my head and said, "He's right here...he's behind you."  Then he laid back down, sound asleep, and didn't respond to my laughter and questions.  

A couple of months ago we had a similar experience.  This time we were both asleep and Dave suddenly shoved his arms under me like a forklift.  I started awake but fell back asleep before I even knew what had happened.  Then he did the same thing a couple of hours later.  This time I asked him, "What are you doing?!"  He replied, "Just making sure you're not sleeping on Sam-it's silly I know."  Of course he had no idea he had done this the next morning.
