She Sleeps?

So there's been incredibly loud hammering, scraping, and rattling going on in the upstairs apartment for the past three hours now, and it's all coming through my ceiling nice and clear. It started about an hour before R's naptime, and I found myself praying the noise-makers would be prompt about pausing for lunch. But, no, not these oh-so-diligent workers. I actually started Googling white-noise makers and was about to purchase the Marpac SleepMate 980A Electro-Mechanical Sound Conditioner on Amazon, when I decided to peek in on R first, certain she'd be rolling around in her crib with her hands clamped over her little ears. But no, actually, she was sleeping the sleep of the dead. Whah?

I don't get it. This is the baby that bolts upright if I even dare breathe wrong while in the room next door, while she's asleep. This is the baby who didn't doze for more than 30 minutes, at 10-minute intervals, during a recent 16-hour international flight, because every little thing woke her up.

Now she sleeps through construction work? And continues to sleep, I might add, longer than she has in...months. I don't know what this means. Oh my god, maybe I better go check to see if she's breathing.
