When it happens · 4 min read
They swallowed a coin (or a toy piece) — now what
You saw it happen, or you found the toy in pieces and did the math — either way, your child swallowed something they shouldn't have, and now you're deciding whether this is an ER trip or something to just keep an eye on.
For most ordinary objects, it's the second one. Here's how to know which situation you're actually in.

What usually happens
Coins are the most common thing toddlers swallow, and most small, blunt objects — including coins — pass through the digestive tract on their own within about three days, with no treatment needed. Watch diapers or the toilet over that window; you don't need to find the object to know it's passed, but it can be reassuring if you do.
When it needs an ER visit right away
Drooling, gagging, trouble swallowing, or refusing to eat or drink means go to the ER now — that pattern suggests something is stuck rather than moving through normally.
Sharp objects, more than one magnet swallowed at once, and button batteries are never watch-and-wait, regardless of whether your child has any symptoms at all. Those three categories get immediate medical attention every time.
Why magnets and batteries are the exceptions
A single small magnet is usually treated like any other blunt object, but two or more magnets swallowed together can attract each other through the walls of the intestine, pinching tissue between them and causing serious internal injury — which is why multiples change the plan entirely.
Batteries cause a different kind of harm — a chemical burn from an electrical current, not a blockage — and that's covered in its own page, since the action needed is completely different.
What to actually watch for over the next few days
Beyond the immediate drooling/gagging check, watch for abdominal pain, fever, vomiting, or blood in the stool over the next few days — any of those is worth a call to your pediatrician even without the drooling/gagging picture.
If three or four days pass with no symptoms and you haven't confirmed it's passed, a check-in call with your pediatrician is reasonable rather than continuing to wait indefinitely.
Common questions
- Do I need an X-ray right away?
- Not usually, unless there are symptoms like drooling, gagging, or trouble swallowing — most straightforward swallows are managed by watching rather than imaging immediately.
- What if I never actually see it come out?
- That's common and not itself a reason to worry. If several days pass with no symptoms, a call to your pediatrician to check in is reasonable rather than continuing to search.
- Is this different for younger toddlers versus older kids?
- The same principles apply across ages, though younger children have a narrower digestive tract, which carries a slightly higher chance of something getting stuck rather than passing through easily.

Still not sure
This page is the general answer. Yours is a specific child.
The advisor can be. It has read everything here, and it knows how old your children actually are — which is the whole difference wherever guidance changes with age. Ask it anything.
- She's got a temperature of 100. Is that something to worry about?
- He's obsessed with space and galaxies — what toys are worth getting him?
Free. It comes with the note.
It answers from the same cited pages you are reading, and when the question is where to go, from the real clinician, hospital and childcare records behind this site — not a link to go search them yourself. It says so when we have not written about something, and it is not a doctor; for anything urgent it gives you the threshold and tells you to call.
