I think alot of people may be forgetting that this is only PART of a much longer video which includes this:
http://www.wesh.com/video/index.html
Caylee singing the lyrics to the Sunshine song, all on her own, very spirited and lively, as well as the part where she is reading the book (different link). All of that is part of the same video. These people had to drive to Mt. Dora, which is about 45 minutes to an hour away. No sure how long they were there, but for most of the video(s), Caylee looked fine and happy. Not drugged or scared at all. I was a pre-school teacher for several years as well as a daycare worker. I had kids that were ages two to three. Very, very often, every day, in fact, I had two year olds and three year olds that would come and sit on my lap and snuggle with me for several minutes, some times 10 or more. Depended on whether they were tired, or feeling cuddly, wanted reassurance, whatever. The kids loved me and liked to sit with me. I have alos seen many of my relatives or my friends' kids' at that age sit with mommy or daddy or grandpa, etc., like that. Isn't that just one of those normal, quiet moments you cherish when you get to steal a short period of calm admist the whirlwind that is usually created by a toddler? I just think she loved grandpa, may have felt a bit tired at that moment, may have been trying to understand grandpa and why he sounded and reacted as he did (not the same as most of the adults around her) and, she was concentrating on the cues she was getting from CA on how to show her love to grandpa, as many, many kids do at that age. She was approaching 3 years old, an age when developmentally, toddlers are extremely eager to please their parents (I know, you all had or knew one who threw hideous tantrums and did not care what you thought, at that age, but that does not change where their overall mindset it at age 3), and tend to notice and/or look for cues on behavior. What is sinister here is that we know this baby likely died the next day, so the sweetness of the moment, the context of the video with such a melancholy song about missing a lost love, the poor, sick grandpa never being able to hold his great-granddaughter again like that, etc, becomes significant. Some may say there was a sort of premonition in both their souls at that moment, of the short time they had/have left on the earth and I will not negate that. You never know. Either way, the video is a solemn foreshadowing of what came next but I think it does not reveal any signs of past abuse or fear of CA, KC or anyone else at that time.
