"It's Five o'clock and I can't sleep"

Awake at 4:40 because that's what time Isaac started crying for me this morning. Second morning in a row, except that yesterday morning we fell asleep together until 6:00. This morning I rocked him to sleep and put him in the pack-n-play in our room, but now Parker is noisily awake, and I don't know why. Somehow Michael and Isaac are still sleeping. Miraculous somehow. But I still don't know what to do about Parker.
