Button Battery Ingestion: Emergency Guide
The short answer
Button battery ingestion is a true medical emergency. If you suspect your child has swallowed a button battery, go to the emergency room immediately -- do not wait for symptoms. A button battery lodged in the esophagus can cause severe chemical burns and life-threatening tissue damage within as little as 2 hours. Do not induce vomiting. Give honey (if over 12 months old) every 10 minutes on the way to the hospital, as it may slow tissue damage.

By Age
What to expect by age
0-12 months
Infants are at extreme risk because their esophagus is small, making it more likely that a button battery will become lodged. Even small batteries can cause devastating injury. Babies in this age group explore by mouthing objects, so prevention is critical. Secure all battery compartments with screws, keep remote controls and other battery-containing items out of reach, and dispose of used batteries immediately. Do NOT give honey to infants under 12 months due to botulism risk. If ingestion is suspected, go to the ER immediately.
12-36 months
Toddlers are the highest-risk age group for button battery ingestion because they are mobile, curious, and still mouth objects. Lithium coin cells (like CR2032) are the most dangerous due to their size and voltage. If you suspect ingestion, do not wait for symptoms. Give 2 teaspoons of honey every 10 minutes (up to 6 doses) while heading to the emergency room. Honey has been shown to reduce tissue damage when a battery is lodged in the esophagus. Do not induce vomiting, as this can cause the battery to re-lodge.
3-5 years
Older children may be able to tell you they swallowed something, but not always. Symptoms of a lodged battery can mimic other conditions: drooling, difficulty swallowing, vomiting, chest pain, or refusal to eat. These symptoms can appear hours after ingestion. If a battery passes to the stomach, it will usually pass through the GI tract within 48-72 hours, but an esophageal lodgment requires emergency endoscopic removal. X-ray is the standard diagnostic tool.
What Should You Do?
When to take action
- There is no "normal" scenario for button battery ingestion -- it is always an emergency that requires immediate evaluation.
- This concern always requires emergency action, not a routine mention to your doctor.
- You know or suspect your child has swallowed a button battery -- go to the emergency room immediately.
- Your child is drooling, gagging, refusing to eat, or having chest pain and may have had access to button batteries.
- Your child has a button battery lodged in the nose or ear -- seek emergency care, as it can cause severe tissue damage in those locations as well.

Related Medical Concerns
My Toddler Swallowed Something
Most small, smooth, non-toxic objects that a child swallows will pass through the digestive tract without causing harm within two to five days. However, button batteries, magnets, and sharp objects are medical emergencies that require immediate attention. If your child swallowed something and is breathing normally with no pain, call your pediatrician for guidance on whether to watch and wait or go to the emergency room.
My Baby Keeps Choking on Food
First, it's important to distinguish between gagging and choking. Gagging is a normal protective reflex that helps babies learn to eat, while true choking is silent and requires immediate intervention. Most "choking" episodes parents describe are actually gagging, which is common and expected as babies explore new textures. However, if your baby frequently struggles with swallowing or shows signs of true choking, it's worth discussing with your pediatrician.
My Baby Eats Non-Food Items (Pica)
It is completely normal for babies and young toddlers to explore by putting objects in their mouths. True pica, which is the persistent eating of non-food substances, is uncommon before age two and may be linked to iron deficiency or developmental factors. If your child repeatedly seeks out and eats non-food items past the typical mouthing stage, it is worth discussing with your pediatrician.
My Baby's Head Shape Looks Abnormal
Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.
Achondroplasia (Dwarfism) in Babies
Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.
Adenoid Hypertrophy and Breathing
Adenoids are lymphoid tissue located behind the nose that help fight infection in young children. When adenoids become enlarged (adenoid hypertrophy), they can block the nasal airway, causing chronic mouth breathing, snoring, nasal speech, and sleep-disordered breathing. Enlarged adenoids are most common between ages 2-7 and are a leading cause of obstructive sleep apnea in young children. Treatment ranges from watchful waiting and nasal steroids to surgical removal (adenoidectomy) if breathing or sleep is significantly affected.
