Parents often worry that water splashed into a newborn’s ear during a bath can cause an infection or damage hearing. For an infant with a normal ear anatomy and intact eardrums, bath water in the outer ear is not dangerous. The ear canal drains on its own, and water does not reach the middle ear through a normal eardrum. This handout covers safe bathing, what truly causes ear infections, what to watch for, and when to pick up the phone.
Key Takeaways
- Bath water in a newborn’s outer ear is not dangerous and does not cause ear infections or hearing loss.
- Ear infections (acute otitis media) are infections of the middle ear, behind the eardrum, and are caused by bacteria and viruses typically migrating up from the nose and throat, not by water in the outer ear.
- Never insert cotton swabs, Q-tips, or anything smaller than your elbow into a baby’s ear canal.
- Newborns do not need daily baths. Two or three baths per week is plenty during the newborn period.
- Call us for fever in a young infant, persistent fussiness with ear pulling, or any ear drainage.
Why Water in the Outer Ear is Not a Problem
The external ear canal is designed to handle moisture. Its skin is water-resistant, it slopes to drain on its own, and it is separated from the middle ear by the eardrum. In a healthy infant, water cannot cross an intact eardrum. That is the short version of why ordinary bath splashes are not a concern.
What Actually Causes Ear Infections
Middle ear infections happen when fluid becomes trapped behind the eardrum and bacteria or viruses that normally live in the nose and throat travel up the eustachian tube into that space. Common contributors include viral upper respiratory infections, allergies, large adenoids, bottle feeding while lying flat, exposure to tobacco smoke, and anatomy: babies have short, horizontal eustachian tubes that drain poorly. Ear infections are common in early childhood, though rates have decreased meaningfully since routine pneumococcal conjugate vaccination (PCV) was introduced. Exclusive breastfeeding for the first 6 months, and continued breastfeeding beyond 6 months, lowers the risk of ear infections. Avoiding secondhand smoke and staying current with vaccines further reduce the risk.
- Annual influenza vaccination from 6 months of age.
- Group childcare is a known risk factor for ear infections. This does not mean avoiding daycare, just that ear infections will be more common.
- Weaning the pacifier after 6 months of age can modestly reduce the rate of ear infections.
Safe Bathing Basics
- Lukewarm water, no warmer than 100°F (38°C). Test on your wrist.
- Two or three baths per week during the newborn period is enough. A damp washcloth for face, hands, and diaper area is fine on other days.
- Support your baby’s head and neck the entire time. Never leave an infant unattended in water, even for a moment.
- Let water run gently over the head during a rinse, or use a cupped hand. Keep rinse water out of the face.
- Pat the outer ear dry with a soft towel after the bath. Do not insert anything into the ear canal.
Ear Hygiene
- Clean only the visible outer ear with a soft, damp washcloth.
- Do not use Q-tips, cotton swabs, or ear candles.
- Earwax is normal and protective. It migrates out of the canal on its own.
- If you see a lot of wax in the canal, or if it seems to be affecting hearing, let us look at it rather than trying to remove it at home.
Signs of an Ear Infection
- In a newborn under 3 months, any fever of 100.4°F or higher is an urgent call regardless of ear findings.
- Fever, especially in combination with other signs.
- Persistent fussiness, particularly at night or when lying flat.
- Ear pulling or rubbing in a distressed child. (Isolated ear pulling in a cheerful baby is usually not an ear infection.)
- Yellow, white, or bloody drainage from the ear canal.
- Decreased appetite or poor feeding.
- Trouble sleeping.
When to Call Us
- Any fever of 100.4°F or higher in an infant under 3 months.
- Ear drainage of any kind at any age.
- Persistent fussiness with fever, especially when your child seems to have ear pain.
- Hearing concerns: your baby is not turning toward your voice, is not responding to sounds, or has failed a hearing screen.
- Water exposure in a baby with ear tubes or a history of a ruptured eardrum (these infants may need special precautions).
Common Questions
Water got in my baby’s ear. Do I need to do anything?
Tilt the head gently to the side, let gravity drain the canal, and pat the outer ear dry. Do not insert anything into the canal.
Can I use over-the-counter ear drops?
Not unless we recommend them. Some OTC drops can irritate a young infant’s canal and are not needed for ordinary bath water.
Does swimming increase the risk of ear infections?
Swimming can contribute to swimmer’s ear (an outer-ear infection) in older children, especially with prolonged water exposure. It does not cause middle-ear infections in healthy newborns, who are not generally swimming yet.
When does my baby need a hearing check?
Florida newborns are screened in the hospital before discharge. If your baby did not pass or the screen was not completed, plan to rescreen by 1 month of age and complete diagnostic audiologic testing by 3 months of age, per AAP recommendations. Failed screens are coordinated through Children’s Medical Services Early Steps in Florida. We can help coordinate.
Bottom Line
Water in the outer ear during a bath is not dangerous for a healthy newborn. The things that actually affect ear health are routine: keep the canal free of cotton swabs, manage colds and allergies, protect your baby from tobacco smoke, and keep vaccines up to date. Call us for fever, drainage, or concerns about hearing.
