Crashed on the Couch

I had to go run some errands this morning, and when I got home I found Hannah crashed on the couch.  I see pictures on Facebook all the time of people's kids asleep in various places of their houses at all times of the day.  But our kids have almost never done that.  Maybe it's because we normally have them on a nap schedule and are largely able to stick to it, I don't know.  But for whatever reason, it's rare for a kid to be asleep in our house in a place that's not their own bedroom.
