Night time wanderings

The past few nights I have been woken up at around 2:30 in the morning to the sound of the TV. Elsie has been getting up, getting her milk from the fridge, then sitting on the couch watching whatever is on PBS in the middle of the night. I'm not even sure if she is fully awake when she does it. We tell her it is still bedtime and lead her back to her bed, and all she says is "ok" and climbs back in bed. One time she came in to my room half dazed and handed me a bag of Alice's yogurt bites at 3am. I guess she thought Alice was hungry...? Not really sure what is going on with her nocturnal activities...
