when were the chloroform searches? this could have set the ball rolling... Caylee was getting in the way, and she saw this- and THEN searched for missing children, ways to kill people, etc.
Or, however, a more innocent explanation- I have ADHD, and if I look something up on the internet, a LOT of times I'll get distracted or super-involved and it will lead like dominos one thing to another, and often ends up someplace disturbing that I'd never have started with-
For example, I was looking up a Church by my home which led to looking at their childrens programs, then to their day care (which talked about storing breast milk), which led to looking up breast feeding, to lactation, to men's lactation (???? apparently its possible), to animals where males raise the young, back to birth, to natural at home births (I saw a video of a baby born into a pool at home), to celibacy, to monestaries, to the sisters of carmel convent...
...what? yeah, that's what I said too. one thing just leads to another- if anyone saw my google history they'd think i was crazy.
ANYWAY, Merry Christmas all!
