I live abroad, so I don't have unlimited access to books in my native language and all the websites were crappy sites with dozens of ads on it, made it unusable.
I was fed up with searching, so I went to ChatGPT, told it to generate me a story in my native tongue about a boy named $MySonsName and his partner $FavoriteAnimalOfTheDay, who is doing $WhateverMySonDidThatDay. It was a good story, used phrases commonly used in children's books in my language, and all.
I think the aspect of being with my son, hugging him while reading something before going to sleep is much more important than who came up with the story. And as parents, after a day of full time work and constantly helping at the household, sleep deprivation, my stories would be two sentences before I run out of ideas.
