Common Cold in Babies & Toddlers
Content reviewed against published AAP, CDC, AAP guidelines
Last reviewed:
The common cold is a viral infection of the upper respiratory tract (nose and throat). Babies get an average of 6-8 colds per year, and those in daycare may get even more. Over 200 different viruses can cause colds, with rhinoviruses being the most common. While uncomfortable, colds are rarely dangerous in healthy babies.
Key takeaways
- The common cold is a viral infection of the upper respiratory tract (nose and throat).
- Duration: Most colds last 7-10 days. Congestion often peaks on days 2-3, then gradually improves. A lingering mild cough can last up to 3 weeks.
- Go to ER if: Difficulty breathing (not just stuffy nose — look for retractions, flaring)
- No vaccine currently available
Symptoms
How It Presents by Age
0-3 months
Nasal congestion can significantly affect feeding since young babies are obligate nose breathers. May cause fussiness and sleep disruption. Fever in this age group always requires medical evaluation even if a cold is suspected.
Risk level: Low (but fever requires evaluation)
3-6 months
Congestion, runny nose, mild cough. May have difficulty breastfeeding due to stuffiness. Generally well-tolerated.
Risk level: Low
6-12 months
Classic cold symptoms. May pull at ears due to congestion (not necessarily an ear infection). Teething-age babies may seem extra fussy.
Risk level: Low
1-3 years
Runny nose, cough, mild fever. May develop secondary ear infections or croup. Better able to cope with congestion than younger babies.
Risk level: Low
Treatment
Supportive care only
There is no cure for the common cold. Antibiotics do NOT work on colds. Over-the-counter cold medicines are NOT recommended for children under 6.
Nasal care
Saline drops and gentle suctioning are the mainstay of treatment for congestion in babies.
Fever management
Acetaminophen (any age) or ibuprofen (6+ months) if baby is uncomfortable.
Hydration
Continue normal feeding. Offer extra breast milk, formula, or water (6+ months).
Home Care
- Saline nasal drops and gentle suctioning before feeds and sleep
- Run a cool-mist humidifier in the room
- Elevate the head of the crib mattress slightly (place towel under mattress)
- Offer extra fluids and frequent feedings
- Use a warm bath to help loosen congestion
- Honey for cough in children over 12 months (1/2 to 1 teaspoon)
- Petroleum jelly under the nose for raw skin
- Keep baby comfortable — extra cuddles help
When to Worry
Go to the ER if:
- Difficulty breathing (not just stuffy nose — look for retractions, flaring)
- Blue lips or face
- Baby under 3 months with fever of 100.4°F or higher
- Refusing all fluids for 8+ hours
- Very lethargic or difficult to wake
- High-pitched or unusual cry
Call your doctor if:
- Baby under 3 months with any fever (100.4°F/38°C or higher)
- Fever lasting more than 3 days
- Symptoms worsening after day 7 instead of improving
- Ear pain or persistent ear pulling with fever
- Thick green discharge for more than 10 days
- Cough lasting more than 3 weeks
Keep an eye on:
- Symptoms lasting more than 10 days without improvement
- Green nasal discharge lasting more than 10 days (may be sinusitis)
- Cough getting worse after day 7
- Pulling at ears persistently
- Fever returning after initial improvement
Prevention
- Frequent handwashing (most important prevention)
- Keep baby away from sick people when possible
- Clean toys and surfaces regularly
- Breastfeeding provides antibodies that help fight infections
- Teach older siblings to cover coughs and sneezes
- Avoid touching baby's face with unwashed hands
- Good ventilation in living spaces

Bottom line
Common Cold is a viral illness that typically resolves on its own. Seek emergency care if difficulty breathing (not just stuffy nose — look for retractions, flaring).
Trust your instincts. If something feels wrong, reach out to your pediatrician. Worrying about your baby means you care — that is a good thing.
