That implies that kids are making an executive decision to stick things up their noses, and search for options. That can be true, like if their noses are really itchy; but it can also just whatever nearby miscellany they happen to be curious about.

But really, its the shape is relevant. Because these are cases that require a parent takes them to ED, meaning they couldnt solve it themselves. A coin that goes up and turns flat is muuuch harder to get out than something with points or edges to grab, like a LEGO man. Perhaps it’s not that kids are sticking less things up there, it’s that coins are more likely to get trapped up there.

I can’t tell you the minds of toddlers man, but if ED’s records say less toddlers are going to ED for nose-junk, then they probably are, and we can speculate on why that is.
