We've always known that Frank is particularly fond of chocolate. The last 24 hours have played this out in a rather funny way. Yesterday afternoon he was beyond-the-beyond in the tired department. But all that was on his sleep-deprived mind was chocolate. He was trying to force Kate out of my bedroom rather loudly and with much crying. Kate finally conceded and I heard him lock the door. I quickly unlocked it and stuck my foot in the door to prevent him from locking it again. Why would Frank suddenly want to lock everyone out of the bedroom? This was a little unusual.
A lightbulb went on in my head. I plucked the package of chocolates off the top of the dresser and returned to the hallway. Frank stormed out of the room screaming for the chocolates. He's an excellent climber and must have figured that if he locked the door he'd have enough time to get to that chocolate. (He was asleep within half an hour).
He didn't go to sleep until late (after that big nap), but still woke up in the middle of the night, crying and begging for ten or fifteen minutes for chocolate, (he's hit that "pleeeeeeeeease!!!" stage - even when he's half-asleep) finally giving up and going back to sleep.
