What do I do right now if my child swallowed a button battery?

Treat it as an emergency — don't wait for symptoms. Call the National Battery Ingestion Hotline / Poison Control at 1-800-498-8666 immediately and head for the ER. If your child is 12 months or older and swallowed it within the last 12 hours, you can give 2 teaspoons (10 mL) of honey every 10 minutes, up to 6 doses, on the way — the honey coats the battery and slows the burning. Never give honey to a baby under 1. Don't induce vomiting and don't let your child eat or drink anything else.

Why are high-powered magnets so dangerous?

If a child swallows two or more, the magnets can attract each other through the walls of the intestines, pinching the tissue between them. That cuts off blood supply and can cause holes, blockages, infection, emergency surgery, and deaths. The danger isn't one magnet — it's two or more meeting up inside the body. Keep magnet sets and any toy or gadget with small strong magnets completely away from children.

Which small household items are most worth locking away?

Button and coin batteries, high-powered magnets, liquid laundry pods, water beads, and any medications top the list. Add window-covering cords (a strangulation risk) and unanchored furniture or TVs (a tip-over risk). These are easy to overlook because they're ordinary household objects — which is exactly why a quick, deliberate sweep of each room pays off.

The hidden home hazards parents miss: button batteries, magnets, and more

Most baby-proofing advice points at the obvious things — outlets, stairs, sharp corners. But some of the most dangerous items in your home are small, ordinary, and hiding in plain sight: the flat battery in a remote, the magnetic letters on the fridge, the laundry pod under the sink. The reassuring part is that once you know which ones matter, neutralizing them takes an afternoon. Let's name the hidden hazards and the exact moves that defuse them.

Button and coin batteries — the 2-hour emergency

These shiny, coin-sized batteries are everywhere: remotes, key fobs, toys, kitchen scales, thermometers, greeting cards, and light-up shoes. They're tempting to little hands and easy to swallow — and if one lodges in the esophagus, a lithium coin cell can cause severe burns in as little as 2 hours.

This is a true emergency, so know the steps before you ever need them. If you suspect your child swallowed one:

Call the National Battery Ingestion Hotline / Poison Control at 1-800-498-8666 immediately and head to the ER. Don't wait for symptoms.
If your child is 12 months or older and swallowed it within the last 12 hours, the National Capital Poison Center guideline says you can give 2 teaspoons (10 mL) of honey every 10 minutes, up to 6 doses, on the way to the hospital. The honey coats the battery and slows the chemical burn.
Never give honey to a baby under 1 (botulism risk), and never let the honey delay getting to the ER.
Don't induce vomiting, and don't give other food or drink.

To prevent it: keep spare batteries locked away, and choose products with screw-secured battery compartments. Tape shut any compartment that pops open easily.

High-powered magnets — dangerous in pairs

Tiny, ultra-strong magnets — the kind in some desk toys, building sets, and fake piercings — are deceptively hazardous. If a child swallows two or more, the CPSC warns the magnets can attract each other through the walls of the intestines, pinching the tissue between them. That can cause perforations, blockages, infection, emergency surgery, and deaths.

Keep high-powered magnet sets out of any home with young children, and check that magnetic toys are age-appropriate and intact. If you suspect a child swallowed magnets, call Poison Control at 1-800-222-1222 and seek care right away, even if they seem fine.

A few more easy-to-miss hazards

Water beads — those tiny decorative or sensory gel balls — expand many times their size when wet. Swallowed, they can keep growing inside the body and cause a blockage. Keep them away from babies and toddlers entirely.
Liquid laundry pods are highly concentrated poisons in a squishy, candy-like package. Store all detergents and cleaners up high and locked.
Window-covering cords are a strangulation risk — go cordless wherever you can, and keep cribs and furniture away from any dangling cords.
Furniture and TVs tip over. Per the CPSC's Anchor It! campaign, the large majority of tip-over fatalities are children 5 and under. Anchor dressers, bookshelves, and TVs to the wall with anti-tip straps or brackets.

Keep these numbers saved

Put both of these in your phone right now, and post them where caregivers can see them:

Poison Control: 1-800-222-1222 for general poison emergencies.
National Battery Ingestion Hotline: 1-800-498-8666 for swallowed batteries.

For any poison emergency where your child is unconscious, having trouble breathing, or having a seizure, call 911 first.

Do a room-by-room sweep

The most effective thing you can do is walk each room at your child's eye level and on their hands and knees, looking for exactly these items. Our full guide to baby-proofing room by room gives you a checklist for that walk-through. Pay special attention to the remote on the couch, the magnets on the fridge, the cleaning supplies under the sink, and any unanchored dresser.

You've got this

It's unsettling to realize how many everyday objects carry real risk — but notice that the list is short and the fixes are concrete. Lock up the batteries and magnets, anchor the furniture, go cordless, and save those two phone numbers. An afternoon of deliberate sweeping turns your home from a maze of hidden hazards into a place you can let your curious explorer roam. You don't have to memorize danger; you just have to remove it, one item at a time.
