Two weeks after giving birth and when they did not allow 2 week old infants to fly on airplanes.
Dunham was already in the Pacific Northwest when Barry was born. No other explanation makes sense.
Stanley Ann Dunham's aunt Eleanor (her dad's sister) lived in Blaine Washington, which was right on the border of Canada. The only hospital nearby was in White Rock Canada, just across the border.
It was common practice in those days to send embarrassing pregnancies off to live with relatives till the baby was born, and this is exactly what happened with this situation.
I depends upon how much time pregnant Stanly Ann was in Kenya. In a video that has been removed from the Internet since the 2008 presidential campaign, Susan Blake, a high school friend of Obama’s mother, gave an interview in which she discussed seeing Dunham shortly after Barack Obama Jr.’s Aug. 4, 1961, birth.
