If your baby has RSV, the most important things you can do are keep their nose clear, keep them hydrated, and watch their breathing closely. Most RSV infections resolve on their own in one to two weeks, and the majority of care happens at home. But RSV can escalate quickly in young infants, so knowing the warning signs that need emergency attention is just as important as knowing the day-to-day care.
Clear Their Nose Before Every Feeding
Babies breathe primarily through their noses, so when RSV fills those tiny passages with mucus, eating and sleeping both suffer. Clearing the nose before feedings is the single most helpful thing you can do, and the timing matters. Suctioning after a feeding can trigger vomiting, so always do it beforehand.
Here’s the process: Lay your baby on their back and place 3 to 4 drops of saline solution into each nostril using a nose dropper. Hold your baby with their head tilted slightly back for about a minute to let the saline thin the mucus. Then squeeze the air out of a bulb syringe, gently place the tip into one nostril, and release the bulb so it draws the mucus out. Squeeze the mucus onto a tissue and repeat on the other side.
Don’t overdo it. Excessive suctioning irritates the nasal lining and can actually make congestion worse. Sometimes the saline drops alone are enough to trigger a sneeze that clears things out on its own. If your baby sneezes after the drops and seems to breathe more easily, you can skip the syringe.
Keep Your Baby Hydrated
Congested babies often refuse to eat because they can’t breathe and swallow at the same time. Smaller, more frequent feedings work better than trying to push a full feeding. For infants, breast milk or formula are the best options because they provide both hydration and nutrients. Contrary to what you may have heard, milk does not make mucus worse.
For older babies who are eating solids, you can supplement with water, diluted apple juice, popsicles, soup, or water-rich foods like watermelon and cucumber. The key is getting fluids in consistently throughout the day, even in small amounts.
Watch for these signs of dehydration, which mean your baby needs medical attention right away:
- No wet diapers for 8 or more hours
- Dry mouth or no tears when crying
- A sunken soft spot on the top of the head
- Extreme sleepiness or difficulty waking
- Refusing all fluids for 12 or more hours
Make Breathing Easier at Home
Run a cool mist humidifier in the room where your baby sleeps. The moisture helps loosen congestion and makes breathing more comfortable. Use a cool mist model specifically, not a warm steam vaporizer, which poses a burn risk. Steamy baths during the day serve the same purpose and can offer temporary relief.
Keep your baby’s head slightly elevated when they rest. RSV symptoms tend to appear in stages rather than all at once, so congestion that seems mild on day two may worsen by day four or five before gradually improving. Most infections clear within one to two weeks.
Managing Fever and Discomfort
Acetaminophen (Tylenol) is safe for young infants and can help bring down a fever and ease general discomfort. Ibuprofen (Motrin, Advil) should not be given to babies under 6 months old. Always dose by your baby’s weight rather than age, and check with your pediatrician if you’re unsure about the right amount.
There’s no medication that treats RSV itself. Antibiotics don’t work because RSV is a virus, not a bacterial infection. Over-the-counter cough and cold medicines are not recommended for infants.
Warning Signs That Need Emergency Care
Most babies with RSV recover at home, but some develop breathing problems that require hospital support. You need to know what these look like because they can develop over hours, not days.
Call your pediatrician or go to the emergency room if you see any of these:
- Nasal flaring: the nostrils spread wide with each breath
- Chest retractions: the skin between or below the ribs pulls inward visibly when your baby breathes in, or the stomach strains noticeably with each breath
- Fast breathing: noticeably more rapid than normal, especially at rest
- Color changes: bluish or grayish tint around the lips, fingertips, or face
- Pauses in breathing: your baby stops breathing for several seconds at a time
Babies under 6 months, premature infants, and those with heart or lung conditions are at the highest risk for severe RSV. If your baby falls into any of these categories and develops even mild breathing changes, err on the side of getting evaluated sooner.
What Happens If Your Baby Needs the Hospital
If RSV gets severe enough to require hospitalization, the treatment is supportive. There’s no antiviral drug that cures it. Hospital care typically focuses on two things: helping your baby breathe and keeping them hydrated.
For breathing support, doctors may use a gentle stream of humidified air or oxygen delivered through small nasal prongs. This makes each breath more effective without requiring a ventilator in most cases. For hydration, if your baby can’t feed safely because of breathing difficulty, fluids can be given through an IV or a thin tube that goes through the nose to the stomach. Both methods work equally well. Most hospitalized babies improve within a few days, though some need closer to a week.
Protecting the Rest of Your Household
RSV is highly contagious and spreads through respiratory droplets and contaminated surfaces. The virus survives for many hours on hard surfaces like tables, crib rails, and countertops, though it dies more quickly on soft surfaces like hands and tissues. Wash your hands thoroughly before and after caring for your baby, and clean frequently touched surfaces daily. Keep sick siblings away from the baby as much as possible.
RSV season typically runs from fall through spring. If your baby hasn’t already been infected and is entering their first RSV season, ask your pediatrician about preventive immunization. A long-acting antibody injection is recommended for infants younger than 8 months during RSV season if the mother did not receive the RSV vaccine during pregnancy or if her vaccination status is unknown. Some higher-risk children, including those with chronic lung disease, severe immune deficiency, or cystic fibrosis with significant lung involvement, qualify for a dose before their second RSV season as well.
