From the article:
"Me in my long hair years," he said as he pointed to the photograph. "And this is Ann, this is Barack's mother, and this is Barack. Barack's about 12."
Aren't there two birthdates for Maya? I believe Aug 1970 as well as the Sept 1971 date.
BO says his father came to visit Christmas time when he was 10. So that would be Dec 1971-Jan 1972. Both dates after Maya's two birthdates.
But I also noticed that Ann did not gain weight for at least a couple years after Maya's birth. She is still more slim in this pic - Maya maybe ~18 months (?). That would make BO ~ 10.5-11.5 (?)
Ann had problems with her weight even back in the years she lived in WA state and I guess she eventually gave up on her attempts at weight control. The pictures of her at Jr’s wedding show this. Perhaps when she first had Maya running around she was able to keep the weight off but after sitting in class she developed more “secretary sprawl” which she never lost.
