Looks like some people can't tell the difference between a studio shot, one tinted, one black and white, in which she's wearing the same dress, and an outdoor photograph that is a still from a video and subsequently poor quality and somewhat distorted? She's tied her hair back that's all, and she's only a few months older, she's as much older in that centre image as the child she is holding, is older.
They can call that child whatever they like, he's still simply the son she had in Kenya in 1965, and the dark boy standing with them looks at least five or six years old.
