Who says she took the baby to Washington? She did so well in her classes, maybe she left the baby with Grandma? This woman never bonded with her child, and this early separation may prove why. She abandoned him several more times in his short childhood.
Seriously, we should NEVER, and I mean NEVER, elect as our President someone who had a childhood so lacking in unconditional love. We should almost never elect a President who desperately wants the job, anyway...
Grandma had a full time job in a bank.
If Ann was sans baby Barry, one would think she would have taken a regular course-load in the Fall quarter 1961, instead of two night courses, which was the same courseload she took in the Winter quarter when we know she had baby Barry based on the baby-sitting recollections of her neighbor.
So the evidence points to Ann being with baby in Seattle in the Fall quarter.
