Notice anything out of the ordinary? Sometimes, it starts with small changes: Your toddler skips their afternoon nap, fusses through dinner, and clings tighter than usual. By morning, you see them struggling with a wheezy cough, a runny nose, and a tired look in their eyes.
These subtle, initial signs can be easy to overlook, but they might be early symptoms of RSV. It is a common infection that affects nearly all children in the U.S. and sends around 58,000 kids under five to the hospital each year. In some cases, RSV can quickly become serious among infants.
At CMCFresno, we understand that when your little one isn’t feeling well, it’s hard not to worry. We’re here to help you feel less overwhelmed and more confident in caring for your child. This blog will walk you through what RSV looks like in babies and toddlers, when to check in with your doctor, and what you can do at home to help your little one feel better.
Catch the Symptoms Before They Get Serious
Respiratory syncytial virus, or RSV, is a common virus that affects the lungs and breathing passages. It spreads easily through sneezes, coughs, or by touching surfaces with the virus on them (something kids do a lot). While RSV usually causes mild cold-like symptoms in older kids and adults, it can be more serious for babies and toddlers.
RSV season typically runs from October to March. During these cooler months, it’s important to be alert, especially when kids spend more time indoors and viruses spread quickly.
Some children are more likely to get very sick from RSV, including:
Toddlers and infants have smaller airways and less developed immune systems, making it harder for them to fight off the virus. Even a minor inflammation or mucus can make breathing more difficult.
Knowing the basics of RSV in babies helps you stay prepared. Next, we’ll break down the symptoms to watch for and when to call your pediatrician.
At first, RSV may seem like a mild cold—but it can sneak up on you. The early signs are easy to miss during cold and flu season. That’s why it’s important to keep a close eye on how your child is feeling and acting.
Here are some of the most common RSV symptoms:
If your child has one or more of these symptoms, it doesn’t always mean RSV. But when several signs show up together, it’s time to be more cautious.
Important Note: RSV Symptoms usually appear in stages, not all at once. That runny nose on Monday might turn into a cough by Wednesday.
Most cases of RSV symptoms in kids can be managed at home, but some signs tell you it’s time to reach out for medical help. Call your pediatrician or visit an urgent care center immediately if you notice any of the following:
If you’ve reached out to your pediatrician because your child’s symptoms are worsening, you might wonder what happens next.
At the clinic, the doctor will do a thorough check-up, starting with a few key steps:
The pediatrician will listen to your child’s breathing and check for signs of labored respiration, wheezing, or chest congestion.
A quick, gentle swab from the nose can help confirm if your child has RSV. It’s fast and usually done in the clinic.
The doctor will monitor your child’s oxygen levels, heart rate, and temperature to assess how your child is handling the virus.
Depending on how severe the symptoms are, your pediatrician may suggest:

Make sure to also ask your pediatrician about the RSV vaccine, which can help protect against high-risk infants from severe RSV infections.
