Aidan, 5, has taken to water like, well, I was going to say a fish but that sounds a little too obvious. Let's say he has taken to it like a 5-year-old boy who loves to swim. Yes, that's far more witty.

As I continue the never-ending excitement that is "Learning All About Aidan," I have been delighted to find out how much the water means to him. At his camp, he swims twice a day and that is fantastic. He has two great teachers - Alex and Dan - who are young and full of mirth and craziness (just like Aidan likes it). His camp day is complete only when he has been tossed around the pool, gone underwater to touch the bottom, and has wound up absolutely exhausted. On the few days where there has been rain and the swimming curtailed, he is heartbroken. "Tomorrow," I tell him. "There's always tomorrow."

He has taken this love for swimming to his weekends, too, strongarming his grandparents to take him to his great-grandmother's pool. There he suns himself, swims for hours on end, and charms the heck out of 85-year-old women. He is funny and full of life, and I dare say, I think he makes some of the residents very, very happy.

When the family goes to a pool party, you better have Aidan's suit on him. Like a moth to the flame, he lunges poolside and is reluctant to exit until the car is running, the sun has gone down and he has been repeatedly threatened with a loss of nighttime books and songs.

I admit, I was not unlike the boy when I was a child. If there was a pool to be found, I was in it. I liked to sink to the bottom and push off, like Superman escaping Earth's gravity. I would dive for coins, attack friends with inflatables and fling myself off of diving boards.

Now, three decades later, I get to watch an insane nearly-4-foot-tall lunatic who does the same thing. And what am I doing? Jumping in beside him. After all, there are coins to be found, the children of friends to be attacked and diving boards to throw myself off of.

Hey, there's no way I can let Aidan have ALL the fun.
