No, you're right, she has always insisted that this particular nanny has, or at least took, Caylee. If KC really believes this nanny has the child, (it's possible), I have wondered if she actually saw the nanny take possession of Caylee or if she just believes that happened because she dropped the child off there but didn't actually watch until the nanny had Caylee. Or even if she had actually left the child with other friends or acquaintances, something happened during their watch, Caylee got lost or wandered off, they found out somehow that woman had been there, thought she took Caylee...or a tragic accident occurred while friends were watching Caylee, KC was afraid of incriminating them or herself or was afraid of facing her parents with that, concocted the nanny story...Or even that some friend or acquaintance harmed Caylee but convinced KC the nanny has her and she believed them and elaborated from there. I honestly don't know what happened, there are simply so many possible scenarios regarding the nanny. I do still think it's within the realm of possibility that somebody, even this particular nanny, acquaintance, whatever she really was, actually has Caylee.
