Ear Infections in Babies & Toddlers
Content reviewed against published AAP, CDC, AAP guidelines
Last reviewed:
Ear infections are one of the most common reasons parents bring young children to the doctor. They occur when fluid builds up behind the eardrum and becomes infected by bacteria or viruses. By age 3, about 75% of children will have had at least one ear infection. They often follow a cold or upper respiratory infection.
Key takeaways
- Ear infections are one of the most common reasons parents bring young children to the doctor.
- Duration: Pain usually improves within 24-48 hours (with or without antibiotics). Fluid behind the eardrum may persist for 4-6 weeks after infection resolves.
- Go to ER if: Swelling and redness behind the ear (possible mastoiditis)
- A vaccine or immunization is available
Symptoms
How It Presents by Age
0-6 months
May show as irritability, poor feeding, fever, and pulling at ears. Difficult to diagnose as babies cannot verbalize pain. AAP recommends antibiotics for all ear infections in this age group.
Risk level: Moderate — always needs treatment
6-12 months
Classic presentation with ear tugging, night waking, fussiness with lying down, and often following a cold. May have fever.
Risk level: Moderate
1-2 years
Peak age for ear infections. May pull at ears, be fussy, have fever, and refuse food. Often recurrent in this age group.
Risk level: Low to moderate
2-5 years
Can often point to or describe ear pain. Still common but frequency decreases as eustachian tubes mature.
Risk level: Low
Treatment
Watchful waiting
For children over 6 months with mild symptoms and non-severe infection (one ear, no drainage), doctors may recommend waiting 48-72 hours to see if it resolves on its own.
Antibiotics
Amoxicillin is first-line when antibiotics are indicated. High-dose amoxicillin (80-90 mg/kg/day) for 10 days (under 2 years) or 5-7 days (over 2 years).
Pain management
Acetaminophen or ibuprofen (6+ months) for pain. Pain relief is the priority regardless of whether antibiotics are prescribed.
Ear tubes
Tympanostomy tubes may be recommended for recurrent infections (3+ in 6 months or 4+ in a year) or persistent fluid affecting hearing.
Home Care
- Use acetaminophen or ibuprofen for pain (most important)
- Apply a warm compress against the ear
- Keep baby upright or elevated during sleep if possible
- Offer extra fluids and frequent feedings
- Do not put anything in the ear canal
- If antibiotics are prescribed, complete the full course
- Use saline drops to address underlying nasal congestion
When to Worry
Go to the ER if:
- Swelling and redness behind the ear (possible mastoiditis)
- Facial drooping on the side of the infected ear
- Very high fever with stiff neck or extreme lethargy
- Sudden severe dizziness with vomiting
- Blood draining from the ear after trauma
Call your doctor if:
- Suspected ear infection in a baby under 6 months
- Fever lasting more than 48 hours
- Fluid or pus draining from the ear
- Symptoms not improving after 2-3 days of watchful waiting
- Child having repeated ear infections
- Concerns about hearing
Keep an eye on:
- Symptoms not improving after 48-72 hours of antibiotics
- High fever (over 104°F) not responding to medication
- Swelling, redness, or tenderness behind the ear
- Child seems very unwell or lethargic
- Recurrent infections (3+ in 6 months)
Prevention
- Pneumococcal vaccine (PCV15 or PCV20)
- Annual influenza vaccine
- Breastfeeding for at least 6 months
- Avoid bottle propping — never let baby drink lying flat
- Avoid secondhand smoke exposure
- Limit pacifier use after 6 months
- Keep daycare group sizes small when possible
- Treat nasal congestion promptly to keep eustachian tubes clear
Contagion & Incubation
Incubation
Typically develops 3-7 days after the start of a cold
Contagious for
The ear infection itself is not contagious. The underlying cold virus may be contagious for 7-10 days.
Duration
Pain usually improves within 24-48 hours (with or without antibiotics). Fluid behind the eardrum may persist for 4-6 weeks after infection resolves.
