Regression or Something Shiny?

I finally got a bumper for Zack's crib last week. We kept finding him with a leg or an arm hanging out between the bars.

Since the new addition, almost every night we go to put Zack down to sleep, we find Kaitlyn has crawled into Zack's crib and curled up with his quilt. She brings along her own pillow and stuffed animals. Apparently, she has decided his crib is cooler than her toddler bed. She is such a stinker.
