What you have written and I have put in bold I am using because you sparked what I am thinking. :tyou:
If Casey drugged Caylee first with cold medicine or chloroform, (and I keep thinking Casey had Caylee in the car seat at one point)she would have been "sleeping" when Casey put the duct tape on her face. IIRC, someone(JoyPath?)said that a person who has been drugged wouldn't(might not)react to the loss of air if they were unconscious. So, here we have a drugged Caylee with Casey applying the three layers of duct tape over her airways to make sure that if Caylee were to awake from the (Casey made sure to give what she thought was a) lethal dose, but put the duct tape on to be sure.
Along with this idea my mind goes to Caylee being wrapped in the Winnie the Pooh blanket as Casey carries a "sleeping" drugged Caylee out to the car to put her in the car seat. I think Cindy was gone at work and George was busy being George. I think Casey withheld Caylee from George in the morning, he did not eat breakfast with her and since he said at one point he had put Caylee in her car seat and waved goodbye, I figure that is a lie. Casey might have marched by George or waited till he was in the backyard/going to the restroom, etc. there are many ways Casey could have carried a drugged Caylee out to her car and put her in the car seat. (in my theory based on all the work of other WS).
Casey grabbed a knife from home to take with her to cut the duct tape, and grabs garbage bags that are in the garage. She drove the car to where she could get in the back seat and put the tape on unconscious Caylee(who looks like a sleeping child in a car seat). When the tape is applied, Casey gets Caylee out of the car seat and into the trunk. Then Casey drives to Tony's where she parks the car and goes to Blockbuster Video with Tony in his Jeep.

ETA: I think George and Cindy may have figured this out, and that is why the conflicting stories for the morning of June 16. Why Cindy made the statement that she listened through the door and could hear both of them "breathing." This statement lends credence to the idea that Casey had Caylee in her room on the night of the 15th because there was a fight. In most statements it seems like Caylee would sleep with Cindy in her room, but if Casey and Cindy had a fight over Caylee on the night of the 15th-Casey may have ran into her room with her. This is when Casey could have, in anger now, given Caylee way too much of a dose of something so that she would be quiet/to kill her.
