I'm going to try this once more, with better organization in my post.
Kaine said this - note BBM -
http://www.kgw.com/news/Kaine-Horman-Terri-was-a-good-person-when-we-first-met-98620944.html
Marriage Date - Terri & Kaine: 4/15/07.
Birthdate of the baby: 11/12/08. (per RO below)

PPD comes on AFTER birth. (Many references on this.) Depression following birth anywhere from 6 months to a year after birth could be PPD.
So, Kaine says Terri was a "good person" when they met and up until 2008. So for 8 months after the marriage Terri continues to be a "good person".
Then... if Kaine means what he said about being a "good person" up until 2008...
Beginning 2008, Terri is no longer the same "good person" AND Terri gets pregnant. (approximate date - based on 40 wks ) Terri gets pregnant 2/6/08. Birth 11/12/08. After birth, for 1.5 years Terri "shows signs here and there of emotional distress".
IMO - if Kaine means what he says - Kaine is suggesting that Terri's bad behavior coincides with a timeframe just 8 months after their wedding and just prior to to the beginning of the pregnancy - and not the end of the pregnancy.
This is just a little notation clarifying Kaine's "character/personality" notes regarding Terri against the timeline of the pregnancy.
It's interesting to me because it leaves the option open that this is not PPD or perhaps not just PPD alone. It also allows the question as to a pre-existing issue prior to the pregnancy that was, perhaps, exacerbated by PPD and/or the pregnancy. (I have read briefly that women with BPD & other personality disorders experinece greater incidences of PPD...)
I have been having a hard time with the idea that this is all PPD. Given Kaine's written explanation of the timing of Terri's changes, (as in - before or coincidental with the beginning of the pregnancy and NOT the end of the pregnancy), I think he opens the door to other issues with Terri.
It also helps explain how the pregnancy itself may have camouflaged - or muddied somewhat the recognition of severe character changes in Terri (Kaine & co. thinking "oh, she's irritable, different, anxious, etc... but it's because she's pregnant...") that otherwise might not have been overlooked had Terri not been pregnant.
JMHO, and Kaine's reply e-mail to the press "up until 2008" may not be what Kaine means to say. We shall see...
