Parenting and Productivity

Before I had Z, I considered myself fairly productive. I finished the first draft of a novel, which seemed like a pretty big deal at the time. It took me about two years.

After Z, I finished another novel draft in one year. My third one took about six months or so.

Today, just finished the first draft of my fourth novel, and it took less then three months. (It’s really really short, and really really horrible, but that’s what revision is for.)

So what I’m wondering is, am I more productive with the writing because I know how fleeting free time is, so I don’t waste it? Or is it that I’m “growing up” finally, and getting a little more self-disciplined? Or am I  a more effective writer, because of all the practice? Or all of those, or none?

And before you think I’m writing more because I’ve let housework fall by the wayside, no, I can assure you, I’ve always let housework fall by the wayside. (And I always will.) (Yes, that’s a promise.)

Does anyone else have experience with this – whether for you, or someone you know? More productive with kids, as unbelievable as it sounds?
