Croup and Daycare: Policy, Barky Cough and When to Return

Updated November 2026.

Croup is a viral infection that swells the upper airway and causes a barky, seal-like cough, often worse at night. A child with croup can usually go back to daycare once they have been fever-free for 24 hours without fever-reducing medicine and feel well enough to join in. A child who has stridor, a harsh sound when breathing in, while resting needs to see a doctor right away.

Here is how to spot croup, care for it at home and decide when your child is ready for daycare.

What croup looks and sounds like

• A barky cough, like a seal
• A hoarse voice or cry
• Cold symptoms first, such as a runny nose and mild fever
• Symptoms that are worse at night
• Sometimes stridor, a harsh, raspy sound when breathing in

Croup is most common in children from about 6 months to 3 years, when airways are small. It often appears in fall and winter. Most children with croup just have a barky cough. It usually lasts about 5 to 6 days, and the cough can linger up to 2 weeks.

Is croup contagious?

The viruses that cause croup spread like cold viruses, through coughs, sneezes and hands. That is why croup can move through a daycare classroom. Older children and adults who catch the same virus often just get a cold.

When your child can go back to daycare

• No fever for 24 hours without fever-reducing medicine
• No stridor while resting
• Your child feels well enough to take part in normal activities

A lingering barky cough on its own is not usually a reason to stay home. Illinois daycare centers screen children daily and exclude children with fever and a change in behavior or with difficult breathing. Ask your center about its policy, and read our guide to daycare fever rules.

Home care for mild croup

• Keep your child calm. Crying can make croup worse. Hold and comfort your child.
• Try cool air or steam. Some parents find that breathing cool night air or warm, moist air from a steamy bathroom helps their child feel better, though studies have not shown it shortens croup.
• Offer fluids and let your child rest.
• Sleep nearby for a few nights, since stridor can start suddenly at night.
• Avoid tobacco smoke, which makes croup worse.

Doctors often treat moderate croup with a steroid medicine to reduce airway swelling.

When to get help

Call 911 if your child:

• Is struggling to breathe or cannot speak or cry because of breathing
• Has skin pulling in between the ribs with each breath
• Has lips or face turning blue or gray
• Is drooling or cannot swallow

Call your doctor now if your child has stridor while resting, is under 1 year with stridor, or seems very sick. Call during office hours if croup keeps coming back or the barky cough lasts more than 2 weeks.

Frequently asked questions

Can my child go to daycare with croup?

Once they have had no fever for 24 hours without medicine, no stridor at rest, and feel well enough to join in, they can usually go back.

How long is croup contagious?

Croup viruses spread like cold viruses, most easily in the first days of illness while fever and cold symptoms are present.

Is croup worse at night?

Often, yes. Stridor can start suddenly at night, so keep your child calm and sleep nearby for a few nights.

Can adults catch croup from a child?

Adults can catch the virus, but usually just get cold symptoms.
