Fever, sore throat and body aches are never fun, but it’s especially hard when it’s baby who’s suffering from the flu. Unfortunately, it happens more often than we’d like, so it’s a good idea to be prepared. Here’s how to spot the telltale flu symptoms in babies, plus how to safely treat it and prevent your child from getting sick again.

What Is the Flu?

Influenza, aka the flu, is a respiratory illness caused by viruses, says Danelle Fisher, MD, FAAP, chair of pediatrics at Providence Saint John’s Health Center in Santa Monica, California. Like many illnesses, the flu in babies can range in severity from mild to severe and can, in rare cases, potentially even be fatal. According to the Centers for Disease Control and Prevention (CDC), babies, particularly those under 6 months, have a higher risk of developing serious flu-related complications because they can’t yet be vaccinated.

Unfortunately, it’s not uncommon for infants to come down with the flu. “They get it just like they get colds,” says Ari Cohen, MD, chief of the division of pediatric emergency medicine at the MassGeneral Hospital for Children in Boston. The number of baby flu cases each year ultimately depends on the severity of the flu season; if the flu is running rampant, babies are at a higher risk of contracting the illness too. According to estimates from the CDC, 7,000 and 26,000 children under the age of 5 have been hospitalized since 2010 due to the flu. Tragically, during the 2021 to 2022 season, there were 43 pediatric deaths due to the flu.

What Causes the Flu in Babies?

Babies contract the flu the same way adults do: by coming into contact with influenza viruses when infected people cough, sneeze or talk, Cohen says. While person-to-person contact is the most common way baby flu is transmitted, little ones can also get sick from touching a surface that’s contaminated with the virus and then putting their hands in their mouth.

Is the flu contagious?

The flu is easily passed from one person to the next—in fact, “we’re finding out that the flu tends to be a little more contagious than we thought,” Fisher says. People tend to be sick for a day before they start to exhibit symptoms, and may unknowingly pass it onto baby before they realize they have the flu. There’s now evidence that little ones can get sick just by breathing or being in the same room as someone with the flu, Fisher says.

How to avoid giving baby the flu if you’re sick

Luckily, there are many ways sick parents can prevent passing the flu to baby, including properly covering coughs and sneezing and practicing good hand-washing and hygiene.

Wondering if you can still breastfeed baby with the flu? The CDC says yes. The flu cannot be transmitted through breast milk, and parents should continue to breastfeed regardless if they or baby has the flu. Just be careful to wash your hands with soap before touching baby or any of their things. If you’re too sick to breastfeed, the CDC says it’s also okay to have a healthy caregiver feed baby expressed breast milk from a bottle.

Flu Symptoms in Babies

So how can you spot the flu in babies? Infants experience the same symptoms as adults, but of course can’t clearly tell you what they’re feeling. Plus, it might be hard to tell the difference between a cold and the flu in infants. But, unlike the cold, influenza tends to come on quickly and often prompts the following flu symptoms in babies:

Let your pediatrician know right away if you see any of the following symptoms in baby:

  • Trouble breathing
  • Bluish skin color
  • Inability to eat
  • No tears when crying
  • Not waking or interacting with others
  • Not wanting to be held
  • Fever with a rash

Baby Flu Treatment

If baby is exhibiting flu-like symptoms, your pediatrician will likely give them a flu test in the office. If it’s positive and you’ve caught it within the first 48 hours of baby showing symptoms, infants 2 weeks and older will likely be treated be treated with Tamiflu, an antiviral prescription medication that can shorten the course of flu in infants by a day and lower the risk of complications, says Gina Posner, MD, a pediatrician at MemorialCare Orange Coast Medical Center in Fountain Valley, California.

If your child’s symptoms are mild, your pediatrician may recommend merely treating them to make your little one more comfortable. “I don’t treat the vast majority of pediatric patients with anything aside from Tylenol for achiness and relief,” Cohen says. However, every doctor is different and may prescribe an alternate course of treatment. Wondering if over-the-counter infant cold and flu medicine is safe to give? While Infants’ Tylenol may be used to relieve flu symptoms in babies and toddlers, it’s always best to check in with your pediatrician first.

To help alleviate baby’s flu symptoms and congestion at home, parents can use humidity (through a steam room or humidifier), as well as nasal aspirators. But the best way to treat the flu in babies is to make sure they get plenty of rest and drink lots of liquids.

How long does the flu last?

There’s a pretty wide range in how long babies can be impacted by the flu. For some, baby flu is short lived, with a fever that lasts a few days and a cough that hangs on for a week, Posner says. In others, the fever can last a week and the cough can stick around for a month. “It’s hard to tell who is going to get it the worst,” she says.

Baby Flu Prevention

Of course, the best way to keep your child safe from the flu is to do what you can to prevent baby flu from developing in the first place. Some things are out of your control, of course, but there are a few ways you can help keep your little one flu-free.

  • Practice good hand hygiene. Encourage others to always wash their hands thoroughly with soap and water before coming into contact with baby or any of their things, Fisher says.

  • Avoid being around sick people. If someone has a cough or runny nose, ask them to postpone their visit to see your little one.

  • Stay away from crowded areas. Keeping baby away from malls, stores and other crowded areas during flu season can help lower the risk, Posner says.

Flu shot for babies

The CDC strongly recommends the flu shot for babies who are 6 months and older. It’s given in two doses, four weeks apart, to help their little bodies mount the best antibody response, Fisher explains. It should be administered ideally by October, before flu season is in full swing. There are several types of influenza viruses, but the shot protects baby against those that research suggests will be the most common that season. Because of this, the effectiveness of the flu shot for babies can vary from year to year, Posner says, but statistics show that kids who get the shot are less likely to have serious complications from the illness than those who weren’t vaccinated. (According to the CDC, approximately 80 percent of the fatalities that occurred during the 2021 to 2022 season were in children who weren’t vaccinated against the flu.)

The flu shot can potentially prompt some side effects, but they tend to be incredibly mild, Cohen says. “Occasionally we see a low-grade fever or runny nose, but they’re temporary side effects and usually last for 24 to 48 hours,” he says. “I haven’t had any babies have any kind of severe reaction from the flu vaccine.”

Babies under 6 months old are too young to get the flu shot, so the best way to protect infants from the flu is to make sure baby’s caregivers get vaccinated. If you get the flu shot while pregnant, your body produces antibodies that then pass through the placenta to baby, Cohen says, helping to protect your little one even after they’re born. Once you begin to breastfeed, you continue to pass antibodies onto baby through your breast milk.
