Most childhood pneumonia is treated at home with antibiotics, fluids, rest, and careful monitoring. The specific treatment depends on whether the infection is bacterial, viral, or caused by an atypical organism, and on how sick your child is. Kids with mild to moderate symptoms typically recover within one to two weeks, though a lingering cough can last longer.
Bacterial vs. Viral vs. “Walking” Pneumonia
The type of germ causing the infection determines the treatment approach. Bacterial pneumonia, the most common type requiring antibiotics, is typically treated with amoxicillin for about five days. Your child’s doctor will calculate the dose based on your child’s weight. Most kids start feeling noticeably better within two to three days of starting the antibiotic, but it’s important to finish the entire course even once symptoms improve.
Viral pneumonia, including cases caused by influenza, doesn’t respond to standard antibiotics. Treatment is mainly supportive: fluids, rest, and fever management. If the flu is the suspected cause, an antiviral medication may be prescribed, especially if it’s caught early.
“Walking pneumonia” is caused by a different type of bacteria (Mycoplasma) that’s especially common in school-age children. It tends to come on gradually with a dry cough, low fever, and fatigue. The first-line treatment is azithromycin, given as a slightly higher dose on the first day followed by a lower dose for the next four days. Kids with walking pneumonia often feel well enough to go about their day, which is how it got its name, but they still need the full course of treatment.
What Home Care Looks Like
Whether your child is on antibiotics or recovering from a viral case, the home routine is similar. Keep fluids front and center. Water is fine for most kids, but if your child is vomiting or has diarrhea, an oral rehydration drink like Pedialyte replaces lost salts and minerals more effectively. Don’t rely on these drinks as the only source of nutrition for more than 12 to 24 hours, though.
For fever and body aches, acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) both work well. Ibuprofen should not be given to babies under six months old. Never give aspirin to anyone under 18 because of its link to Reye syndrome, a rare but serious condition. Always dose by your child’s weight, not just their age.
A cool-mist humidifier placed near your child’s bed can help loosen congestion and make breathing more comfortable, especially at night. Clean the humidifier regularly to prevent mold buildup. Beyond that, let your child rest as much as they want. They don’t need to stay in bed all day, but they shouldn’t be running around at full speed either.
How Doctors Decide Your Child Needs the Hospital
Most kids with pneumonia recover at home, but certain signs mean your child needs closer monitoring in a hospital. The main criteria doctors use include:
- Oxygen levels consistently below 90%. An oxygen saturation of 92% or lower is a strong predictor of pneumonia serious enough to require admission. Levels below 96% raise concern in any age group.
- Inability to keep fluids or medications down. A child who can’t stay hydrated orally may need IV fluids.
- Moderate to severe breathing difficulty. This includes visible rib retractions (skin pulling in between the ribs with each breath), nasal flaring, or grunting.
- Altered mental status. Unusual drowsiness, confusion, or difficulty waking up.
- Failed outpatient antibiotics. If your child isn’t improving after two to three days on oral antibiotics, the treatment plan needs to change.
In the hospital, children typically receive IV antibiotics for five to seven days. Once they’re improving, eating, and drinking, doctors switch to oral antibiotics and send them home to finish the course.
How to Spot Breathing That’s Too Fast
One of the most reliable signs of pneumonia in children is a breathing rate that’s faster than normal. The thresholds vary by age. For newborns up to two months, faster than 60 breaths per minute is concerning. For babies two to twelve months old, the cutoff is 50 breaths per minute. For toddlers and preschoolers (ages one to five), it’s 40. For kids over five, anything above 20 breaths per minute is considered elevated.
To count your child’s breathing rate, watch their chest rise and fall for a full 30 seconds while they’re calm or sleeping, then double the number. Crying, fever, and activity all speed up breathing temporarily, so try to measure during a quiet moment.
What Recovery Actually Looks Like
Parents often expect pneumonia to clear up like a regular cold, and the timeline can be frustrating. Some children bounce back and return to normal activities within a week. Others take a month or more to feel fully themselves again, even after the infection itself has cleared. A lingering cough is common and doesn’t necessarily mean the pneumonia is getting worse or that the antibiotics didn’t work.
Fever typically breaks within the first few days of appropriate treatment. If it doesn’t, or if it goes away and then returns, that’s worth a call to your child’s doctor. It could mean the antibiotic isn’t targeting the right bacteria, or that a complication like fluid around the lung has developed.
A follow-up chest X-ray is not routinely needed for healthy children who recover without complications. If your child had a straightforward case and is feeling better, their doctor will likely skip the repeat imaging. Follow-up X-rays are reserved for children whose symptoms aren’t resolving as expected or who had complicated pneumonia to begin with.
When Antibiotics Aren’t Working
If your child has been on amoxicillin for two to three days with no improvement, the doctor may switch to a different antibiotic or add a second one. Sometimes what looks like typical bacterial pneumonia turns out to be caused by Mycoplasma or another atypical organism, which requires a different class of antibiotic. In older children (over five), doctors may add azithromycin to cover this possibility.
Children with penicillin allergies have several alternative options. The specific choice depends on how severe the allergy is. A child who got a mild rash from amoxicillin in the past can often safely take a related antibiotic from a different family. A child with a history of a serious allergic reaction will need a completely unrelated drug. Make sure your child’s doctor knows the details of any previous reaction, not just that an allergy exists.
Preventing the Next Round
Pneumonia in kids is often preceded by a cold or flu, so the same habits that prevent those infections help prevent pneumonia too. Handwashing is the single most effective measure. The pneumococcal vaccine, part of the standard childhood immunization schedule, protects against the most common bacterial cause of pneumonia in young children. The annual flu vaccine also reduces risk, since influenza can lead to secondary bacterial pneumonia.
Children with asthma or other chronic lung conditions are at higher risk for pneumonia and tend to have more severe cases. Keeping asthma well-controlled with regular medication reduces that risk. Exposure to secondhand smoke also increases susceptibility, so keeping your home and car smoke-free makes a measurable difference.
