Caylee was almost three and really beginning to verbalize. Quetion: What could be worse for a patholgical liar like Casey? Answer: A talking three year old. From this child speech development page: http://www.childdevelopmentinfo.com/development/language_development.shtml 36 Months: Use pronouns I, you, me correctly Is using some plurals and past tenses Knows at least three prepositions, usually in, on, under Knows chief parts of body and should be able to indicate these if not name Handles three word sentences easily Has in the neighborhood of 900-1000 words About 90% of what child says should be intelligible Verbs begin to predominate Understands most simple questions dealing with his environment and activities Relates his experiences so that they can be followed with reason Able to reason out such questions as "what must you do when you are sleepy, hungry, cool, or thirsty?" Should be able to give his sex, name, age Should not be expected to answer all questions even though he understands what is expected ********************************* I think she killed her deliberately. Partly because she was interfering with partying and CA and GA were pressuring her to take better care of Caylee and not constantly leave her with them and partly because Caylee was beginning to speak. Like I said above---disaster to a liar like Casey... For example: Caylee: "Mommy, I had fun when we went to Target and the park and [insert bofriend's name] house yesterday." Say, Caylee says this in front of a different boyfriend or her parents when Casey had told an entirely different story to them. ----that Casey had been at work or school or any number of places she and Caylee hadn't really been.... etc., etc., etc. And if Casey were involved in or around any sort of illegal activity, that would increase her motive even more.
