Patrick and Lilly played downstairs today, with their art stuff, for an hour and a quarter, by themselves, without needing me or fighting! The kitchen is at the top of the stairs, so I could hear them; my favorite was Lilly exclaiming "That looks fantastic!" Patrick came up once to ask for a piece of tape, and occasionally they'd yell up to me or I'd yell down to them. But overall, it was peace. I can't believe they got along that well for that long.
Maybe they're finally growing up some?
