Got sunburned today, but, we finally got a mattress! Yes! Now to get Karl a little cot. I was thinking maybe get him a platform bed of his own, though, and get him one of those super-soft and super squishy mattresses that roll up. That way he could just roll it up and he'd have a small area to play on. But, he likes to keep his stuff in one spot and he'd have to move everything to lay down to go to sleep so I don't think it would work. A cot would be portable, too, so he could take it outside and take a nap when he wanted to.
