I think what bothers me the most about the doll, is that if it's true that she went nowhere without the baby doll, then, in my mind what was done to Caylee was a rash, quick act - another thing to look at is who gave Caylee the baby doll - if it was Cindy then it would be a dig at her to leave it behind
Both my daughters had things they wouldn't go without at that age - my oldest had a stuffed dog, she went nowhere without it - and my youngest had a baby doll and blanket
So this baby doll left behind is very telling to both Caylees demise AND to Cindy - I just don't see why Cindy doesn't see the signs Casey has left her
