In which Isaac goes to sleep

Rocking Isaac at 3 am. He's yelling at me so I put him on the floor. Why should I rock you if you're going to yell at me anyway? Sometimes this makes him appreciate being rocked more. Other times it just makes me feel better.

Repeat twice. The second time, he yells harder on the floor, then stops. And goes to sleep. In the dark, I had placed him with his head on the down pillow I brought to use myself, later. (Don't worry, I can hear him breathing.)

I have -never- seen Isaac go to sleep on his own like that at night. Ever. And I will bet money that Rachel has not, either. (Or she would have told me, in awed tones.)

Now, how to reclaim my pillow without waking him...
