A smiling man and a baby girl posing for photo.
Bob takes his infant daughter for a family photo.
Smiling men are not all named Bob. "Baby Girl" does not always imply that the girl is an infant. Not all photos are family photos.
A baby does not have to be an infant. The smiling man and the baby girl can be posing for a photo other than a family photo.
Not all men are named Bob and a man and baby can pose for a photo and it not be a family photo.
