I decided to stop messing with the "put Lana in her pack 'n' play so that she can remove her clothing, climb out, and run amok" thing and put her in her crib. I wasn't sure how it would go with all three girls in the same room. There was a lot of carrying-on at first, but Maddie and Gwyn slept while Lana bounced around, then Lana must have fallen asleep shortly before they woke up. Thankfully, I was able to collect the other two girls without waking her. We'll see how tomorrow goes!
