I agree with your thought that it was stress-related. This is around the time Cindy's mom and family are worried she might be suicidal. An obviously unstable daughter, a crumbling marriage, more and more financial troubles, dependant grandaughter thrown in the mix.... any one of those issues would be stressful in their own right!
I think we also have seen that Cindy is the "never happy" type. She wants things both ways a lot of times (much like my boyfriend telling me we should have our space, but then getting mad when I go out with my friends... But, I digress
)
(Sorry J its been a long day).
But to give Cindy just a little credit. The birth of Caylee completely blindsided her, and at seven months nonetheless! Yes, it was apparently blatantly obvious to everyone else in the greater Orlando area (and its so nice to have Charless statement to back that up now), but for whatever reason Cindy chose to take KCs lies at face value and ignore the obvious . Now she has just two months to prepare turning the computer room into a nursery, shopping for baby clothes, re-living her own pregnancy experiences, as every grandmother does, (maybe hoping to get closer to her daughter who has always been oddly emotionally distant in the process). Cindy did what she could to see the good in the situation. Then along comes this precious little angel, the best mistake Casey has ever made.
But, heres Cindy, wanting things both ways. SHE wants complete control of everything Caylee from what clothes she wears, to what food she eats, to where she spends her free time. She wants to be the one whose arms Caylee runs to, the one she calls for at night. However, in the past 20 years Cindy has forgotten just how difficult raising a baby is. She wants all the control, but shes 50 now, with a full time job and numerous other stresses. She just cant do it all herself.
Get full custody of the baby?
There goes any chance of getting KC to grow up and start helping or contributing.
Theyd have to find and pay for a baby sitter every time both she and George werent available.
And isnt their marriage crumbling anyway?
And she just turned 50! This baby wont be out of the house until Cindy is nearly 70.
And, I know weve all (myself included) asked why Cindy didnt at least try for custody.
But I dont think thats what she wanted.
I think the co-workers statements are pretty inline with the situation. Being the sole breadwinner and essentially the sole caregiver was exhausting. Cindy was beyond frustrated with all of this. She didnt want full custody, that would just add to her exhaustion.
She wanted full control with KC chipping in how and when Cindy saw fit.
