Every day after lunch, I take a nap. Edwin and Joseph take naps too, but the girls are too old for naps (or rather, would wake up Edwin) so I let them play quietly in our third-floor toy room. When I come get them a few hours later (or longer, depending on how difficult the morning has been), I'm never quite sure what I'll find. Sometimes the couch is turned into a fort. The treadmill might be festooned with various scarves. Sometimes they will have turned a few remaining UAB boxes into forts. Once I found them both asleep on the couch.
A few days ago, they built a train track.
Not bad for a three and five year-old. I guess there's nothing like boredom to inspire creative problem solving.
