One of the things I love about keeping K one day a week is that I can see him evolve and mature over just seven days. Today I noticed his developing sense of humor. He has starting biting down and popping the nipple of his bottle out of his mouth, and he thinks it's hysterical. His mother has told him over and over that he's NOT to do this, but he'll look at me with this face full of mischief, bite down on the thing, pop it out of his mouth and then laugh and laugh as he is squirted in the face with milk. The funniest thing is his laughter. Gosh, he tickles me.
