I was reading ASOIAF and recalled how Catelyn kept wanting to make babies with Ned because she wanted a son that looked like him, especially because Ned has a bastard that looks like a Stark.

I'm wondering what other sort of actions a wife with that sort of insecurity would do to try and be a good wife. I have a story where a ruling queen marries a foreign king with a daughter that looks almost exactly like him, and she's quite insecure especially because the new king and queen look very different, and their eldest son resembles the mother.

I thought of an idea where she eventually DOES birth a son who resembles his father, and she is always carrying him around, unintentionally favours him, and always wants to be seen next to the living proof that she outdid the king's first wife.
