Your baby and the flu
The flu is an easily spread disease. Children under age 2 have a higher risk of developing complications if they get the flu.
The information in this article has been put together to help you protect children under age 2 from the flu. This is not a substitute for medical advice from your health care provider. If you think your baby may have the flu, you should contact a provider right away.

FLU SYMPTOMS IN INFANTS AND TODDLERS
The flu is an infection of the nose, throat, and (sometimes) lungs. Call your baby's provider if you notice any of the following signs:
HOW IS THE FLU TREATED IN BABIES?
Children younger than 2 years old will often need to be treated with medicine that fights off the flu virus. This is called antiviral medicine. The medicine works best if started within 48 hours after symptoms begin, if possible.
Oseltamivir (Tamiflu) in liquid form will likely be used. Although this drug is not approved for use in children younger than 1 year of age, serious side effects are quite rare. After talking about the risk of side effects against the possible complications of the flu in your baby, you and your provider may decide to use this medicine to treat the flu.
Acetaminophen (Tylenol) and ibuprofen (Advil, Motrin) help lower fever in children. Sometimes, your provider will tell you to use both types of medicine.
Always check with your provider before giving any cold medicines to your infant or toddler.
SHOULD MY BABY GET THE FLU VACCINE?
All infants 6 months or older should get the flu vaccine, even if they have had a flu-like illness. The flu vaccine is not approved for children under 6 months old.
The flu shot contains killed (inactive) viruses. It is not possible to get the flu from this type of vaccine. The flu shot is approved for people age 6 months and older.
A nasal spray-type flu vaccine uses a live, weakened virus instead of a dead one like the flu shot. It is approved for healthy children over 2 years.
Anyone who lives with or has close contact with a child younger than 6 months old should also have a flu shot.
WILL THE VACCINE HARM MY BABY?
You or your baby can NOT get the flu from either vaccine. Some children may get a low-grade fever for a day or two after the shot. If more severe symptoms develop or they last for more than 2 days, you should call your provider.
Some parents are afraid the vaccine could hurt their baby. But children under 2 years of age are more likely to get a severe case of the flu. It is hard to predict how ill your child may get from flu because children often have a mild illness at first. They may become sick very fast.
A small amount of mercury (called thimerosal) is a common preservative in multidose vaccines. Despite concerns, thimerosal-containing vaccines have NOT been shown to cause autism, ADHD, or any other medical problems.
However, all of the routine vaccines are also available without added thimerosal. Ask your provider if they offer this type of vaccine.
HOW CAN I PREVENT MY BABY FROM GETTING THE FLU?
Anyone who has flu symptoms should not care for a newborn or infant, including feeding. If a person with symptoms must care for the child, the caretaker should use a face mask and wash their hands well. Everyone who comes in close contact with your baby should do the following:
If your baby is younger than 6 months old and has close contact with someone with the flu, inform your provider.
IF I HAVE FLU SYMPTOMS, CAN I BREASTFEED MY BABY?
If a mother is not ill with the flu, breastfeeding is encouraged.
If you are sick, you may need to express your milk for use in bottle feedings given by a healthy person. It is unlikely a newborn can catch flu from drinking your breast milk when you are sick. Breast milk is considered safe if you are taking antivirals.
WHEN SHOULD I CALL THE DOCTOR?
