I know myself if I had a young baby and was going to the airport to meet or send off someone, especially if that someone had no connection to the baby, I would leave the baby home with grandma.
I think Maya was left with Grandma.
That would mean only three people went to the airport, Stanley Ann, Barack, and Barack. One camera, no pictures of all three. Stanley Ann took one picture, Barack Sr. took the other. No picture of Barack Sr. and Stanley Ann, for obvious reasons.
It's a pity some passerby didn't offer to take a picture of them all together. (I usually do)
