No nap?!!?

Matthew is the world's best napper. He usually sleeps around 2 1/2 -3 hours every afternoon. Today I put him down late (mistake, obviously) and he was quiet for all of 30 min. I was shocked when I heard him jibberjabbering up there. I tried to get him to go back to sleep, but he took his paci (which he uses as a sleep cue, as he does not get one at any other time) and threw it at me. So much for the nap.
