Movies after Midnight???

Ms. A is in an awful phase, she is not sleeping through the night.  Around midnight, nightly she awakes and storms into our bedroom.  Without intending to stomp, her little foot steps can shake the house.  Ms. A brings with her whatever books we read at bedtime, as many stuffed animals as she can carry, her sippy cup of water, and her almost empty sippy cup of yogi (she gets kefir every night before bed).  Along the way from her bedroom she typically drops all of said items in the hallway.  With a loud "gasp" and a flourish she scoops everything up and continues on her way, until she again drops everything and scoops it up.  At this time either Johan or myself, now wide awake, run to her aid.  When we get her and her possessions resettled into our bed she thrashes around for a bit before falling into a less than restful sleep.  Ms. A talks in her sleep.  Actually she waves her arms and legs around calling out "No!"

Last night the routine was unvaried, until sometime after 1:00 AM.  A had already presented herself in our bedroom.  Her books, animals, and sippy cups were in place.  Johan and I were both squished over to the very edge of our king size bed while Ms. A moved about on the other two-thirds of the mattress.  At some point Johan was awakened by...stillness.  Ms. A was no longer in our bed.  He sat up and was able to peer out into the darkness of the living room.  Johan spotted a blonde little girl perched on the sofa in the middle of the night.  As Johan approached he realized Ms. A was staring at one of the boys' Kindle Fires.  A looked up at him, "I watching movie!" she announced before turning back to the tablet.

Ms. A had gotten out of bed all by herself in the middle of the night.  She went out into the living room, located a Kindle Fire, turned it on, found the Netflix application, selected it, and choose a movie.  Aside from the obvious entertainment factor of the story, we are fairly concerned.  I don't know if this behavior would fall into the "sneaky" category, but it certainly falls into the "gutsy" and "defiance" categories.  C and big K would never, never, not ever have done something like this...  Oh, Ms. A, what do you have in store for us???
