Dads: babysitting or watching your kids?

I've caught myself - and had a few other people catch me - using the term "babysitting" when referring to watching my kids without my wife around.

For some reason, "babysitting" is just the vernacular that comes to mind by default for me when I'm watching my kids alone. Of course, being their dad, I'm told, "It's not babysitting when they're your kids!"

It's true. When the kids are yours, can you really call it babysitting? But when you don't normally watch them on your own, what else do you call it? "Watching the kids?" For Jamie, it's just everyday life, but for me, it's not a typical evening. When someone asks, "What are you doing tonight" I don't respond, "Just being a dad, as usual."

So, any suggestions for me? What do you call it?
