You might have something there Grandtante- my own youngest child, now 17, his nanna&grandad, are well, always trying a bit too much, to win his affection, and my son, well yes is more like a cat, he only bothers when HE wants to, and is more aloof, than affectionate, and out of the two of them, prefers grandad more, as he doesn't 'crowd' him, but his nanna, well she used to insist on trying to hug him, or get him to give hugs&kisses, but he's not that type of boy, (so she doesn't do it as much now he's older!) But it makes him shy away, rather than like her more- he's not visiting them this xmas, due to covid, and he has underlying health issues, (and they live over 70 miles away) but the relief is so apparent in him and i do feel sorry for her sometimes.But my own GC also are not seeing me and they feel it keenly, as do i.
