A new one

I know that Bailey's lining up of her toys has stumped many people..me included. That's just how she plays. She does it all the time, but this is a new one. Normally, they're all just lined up facing the same way. I went in her room to clean up her toys and found this. They're lined up 3x3 in perfectly spaced lines. Not only that, but I remember when she did this. I was trying to get her to come sit with me and wind down. She was doing everything she could to stay awake and went in her room to play in the dark. I heard her playing with these toys, but never checked to see what she was doing. So she did this in the dark....
