My sister in law is 6 1/2 months now and barely looks it because she is in great shape and also tall. She was a star track athlete in high school and runs and works out daily.
But on the other hand my best friend looked pregnant at 2 months (okay thats an exaggeration to make a point)
The other thing is that the so called opinionated KOS experts on pregnacy do not have much experience in the matter of pregnancy either, if they do its accidental, deniable, and abortable.
They assume that the Palins' mind set is the same.
If Palins daughter had been pregnant , the baby would have been publicly carried to term, whether daughter got married or not, and brought right into the Palin family.
I had large babies so I always say I waddled at conception!
