@KatastrophicSim That thread was more a misunderstanding of things and the solution post is about medicine so I don't think that's still the same issue.
I do believe it has something to do with ownership. It seems you can't use books that don't belong to the Sim (which just as well might be a bug) but it's strange that for you it stops working at some point in your own house.
I wasn't able to read to children at libraries either cause they didn't own the book. I'm unsure if that was possible at some point.
Any idea when it stops ? Any specific interactions ? Could you try if it works if you buy a new children's book ?
If it happens again with bookcases in your own home, could you share your save ?
@KatastrophicSim It was a book in a stack (First Unicorn). That book didn't have the option but it was also not owned by the Sim (which I don't know if it's a bug or not but it comes down to the issue I pointed out before with off-lot books. You can't read books to children that you don't own).
All others had the read to children interaction on them. I didn't actually tried reading to them cause I thought you're reporting that you don't have the option ?
The option also if course isn't there on non-children's book (just mentioning that)
