A problem with that theory is that Lolo Soetoro and Ann Dunham didn’t meet each other at the East -West Center of the University of Hawaii until Obama was three years old. Ann Dunham and the baby Barack Obama had been living in Seattle, Washington before that.
A woman named Mary Toutonghi was Obama’s babysitter while his mother was in class at the University of Washington.
Mary Toutonghi, who now lives in Soldatna, Alaska, recalls Barack as “a really alert baby, very happy and a good size.” She does not remember him ever crying (although she adds she is sure he likely did but does not remember any undue fussing). She recalls as best she can the dates she babysat Barack as her daughter was 18 months old and was born in July of 1959 and that would have placed the months of babysitting Barack in January and February of 1962.
I'll let you do the math.
