An Alien Has Taken Over Kendall

In all my years (13) of being a mother, I've not had one single child that, at Kendall's age, willingly goes to bed without crying and/or getting out of bed. For one week now, since we moved her out of our room and into her own room with her new toddler bed, Kendall lays down when she's told. She doesn't cry. She doesn't wimper. She doesn't fidget. She doesn't do anything except go to sleep. It's amazing. She's either possessed by Aliens or God saved the best for last.
