Writing while the baby sleeps

I'm pretty disciplined as a writer. I finished Certain Requirements a little at a time, waking up at 6 every morning for months and months to write for 15-30 minutes before work. Writing is a marathon for me, not a sprint.

That's how I work best, a slow and steady schedule that doesn't vary much. Except I'm rewriting this new book as a stay at home mom, either when my wife is with him or while he naps. I've concluded at this point that I absolutely couldn't get this written without my wife. Because I cannot get into the flow of writing when he could wake up at any minute. Also, a lot of the time when I start to write he wakes up. Like as I started writing this. Luckily he's very cute.
