A funny thing happened on the way to bed

So, for about, oh, 19 months now we've been giving this kid milk right before he goes to bed. That's the end of the routine. Bath -- pajamas -- milk. It's all we know. Tonight he threw us for a loop. I sat down to give him his milk and he said "No milk. Sleep. Bed." I tried again to give him his milk. "No milk. Sleep. Bed." Okay, he must be serious. I let him down off the couch and he walked right to his crib and waited for me to lift him in.

Woah.
