I am a bit surprised to see this picture because in My Father Charlie Chaplin Charles Jr said that when he was little Chaplin never hold him, and that he only loved children as an abstract concept. So maybe what he was told about his father was not precise. Thank you for sharing.
He definitely had some "misconceptions". Sometimes he behaved as if he had no idea how babies were made. With Oona, I think he knew having children made her happy, so he went along with it. Perhaps it was also a way to prove his virility as an older man.
