I don’t think you should be concerned too much! My baby has probably put a ton of things in her mouth when she shouldn’t. (Kibble, pieces of baby wipes to name a few) and pretty much everything she could see on the floor. She likes munching on boxes and books as well😂😂😂 so i think you should be ok!
Lol dads 😅 you might find some in his poop,it’s not gonna get stuck in his intestines or anything
My first thought would just be about whether it could be a choking hazard but sounds like that was not an issue! Phew!
