My Toddler Has COVID: What to Do and Watch For

If your toddler has COVID-19, the most important things you can do are manage their fever, keep them hydrated, and watch for a small number of warning signs that need emergency care. The vast majority of toddlers recover at home within a week with basic supportive care. Here’s a practical walkthrough of what to expect and what to do.

What Symptoms to Expect

The most common symptoms in toddlers are fever and cough. Beyond those two, your child may also have a runny nose, sore throat, fatigue, or stomach issues like nausea, vomiting, and diarrhea. Some toddlers get all of these at once; others have a mild fever for a day or two and bounce back quickly.

One pattern worth knowing about: during waves driven by the Omicron variant, doctors saw a notable rise in croup, the barking seal-like cough caused by swelling around the voice box. If your toddler develops that distinctive bark, especially with noisy breathing when inhaling, a cool mist humidifier or a few minutes of cold night air can help calm the swelling while you decide whether to call your pediatrician.

Managing Fever and Pain

Children’s acetaminophen (Tylenol) and children’s ibuprofen (Advil, Motrin) are both safe for toddlers and effective at bringing down fever and easing body aches. Dosing is based on your child’s weight, not their age. As a general guide for acetaminophen liquid suspension: a child weighing 18 to 23 pounds gets 3.75 mL (120 mg), and a child weighing 24 to 35 pounds gets 5 mL (160 mg). For ibuprofen liquid, those same weight ranges get 3.75 mL (75 mg) and 5 mL (100 mg) respectively. Ibuprofen should only be used in children 6 months and older.

You can alternate between the two medications if one alone isn’t controlling the fever, but double-check timing with your pediatrician so you don’t accidentally overlap doses. Never give aspirin to a child.

Keeping Your Toddler Hydrated

Dehydration is the most common complication parents actually need to manage at home, especially when fever, vomiting, or diarrhea are in the picture. A healthy toddler needs roughly 100 mL of fluid per kilogram of body weight per day, which works out to about 34 ounces for a 22-pound child. During illness, they often need more, particularly if they’re losing fluids through diarrhea.

Offer small, frequent sips rather than large amounts at once. Water, diluted juice, breast milk, formula, and oral rehydration solutions like Pedialyte all work. Popsicles count too and can soothe a sore throat at the same time.

Watch for these signs of dehydration:

  • Mild: fewer wet diapers than usual, slightly darker urine
  • Moderate: dry mouth and lips, no tears when crying, noticeably cranky or irritable, skin that stays “tented” when you gently pinch it
  • Severe: extreme sleepiness or difficult to wake, sunken eyes, mottled skin, rapid breathing

Mild dehydration you can usually correct at home by pushing fluids. Moderate to severe dehydration needs medical attention the same day.

Making Your Child Comfortable

A cool mist humidifier in your toddler’s room can ease congestion, calm a cough, and soothe a sore throat. The American Academy of Pediatrics recommends cool mist over warm steam vaporizers because toddlers can burn themselves on hot water or steam. Choose a humidifier rated for the size of the room, keep it about 3 feet from the crib or bed, and use distilled or filtered water. Clean it every two to three days with a diluted bleach solution (one part bleach to nine parts water) to prevent mold and bacteria buildup.

Elevating the head of the mattress slightly can help with nighttime congestion. Saline nose drops followed by a bulb syringe or NoseFrida can clear mucus for toddlers who can’t blow their own nose yet. Warm baths can also loosen congestion and provide comfort when your child is feeling miserable.

Testing Your Toddler at Home

Most toddlers under 2 will need your help with a home rapid antigen test. For children ages 2 to 5, about half can do the nasal swab themselves with coaching, but the other half still need an adult to handle it. Use a gentle touch: insert the swab about half an inch into each nostril, rotate it for about 15 seconds per side, and follow the kit’s instructions from there.

Rapid tests are most reliable a few days after symptoms start. If the first test is negative but your toddler is clearly sick, test again in 24 to 48 hours. A negative rapid test doesn’t always rule out COVID, especially very early in the illness.

When to Go to the Emergency Room

Most toddlers with COVID do not need emergency care. But call 911 or go to the ER immediately if you see any of these:

  • Trouble breathing: ribs pulling in with each breath, flaring nostrils, breathing that looks labored or faster than normal
  • Persistent chest pain or pressure
  • Can’t stay awake or is unusually hard to rouse
  • New confusion or inability to respond normally
  • Color changes: lips, nail beds, or skin turning pale, gray, or blue

Trust your instincts. If something feels wrong even though it doesn’t match this list exactly, call your pediatrician.

When Your Toddler Can Return to Daycare

Current CDC guidelines no longer require a fixed five-day isolation period. Your toddler can return to daycare or regular activities once they’ve been fever-free for at least 24 hours without fever-reducing medication and their symptoms are mild and improving. That said, your daycare may have its own policy that’s stricter, so check with them before sending your child back. Keep in mind that toddlers remain somewhat contagious for several days after symptoms improve, so good hand hygiene and limiting exposure to vulnerable people (grandparents, newborns) for a few extra days is reasonable.

Watch for MIS-C in the Weeks After

Multisystem Inflammatory Syndrome in Children (MIS-C) is rare, but it’s the one thing to stay alert for after your toddler has recovered. It typically appears weeks after the initial COVID infection, sometimes in children who had very mild or even unnoticed cases.

The hallmark is a new fever that comes with some combination of stomach pain, vomiting, diarrhea, a skin rash, or red eyes. In more serious cases, children can develop low blood pressure and signs of shock. MIS-C involves widespread inflammation that can affect the heart, gut, and brain, and it requires hospital treatment. If your toddler develops a persistent new fever with any of those symptoms in the two to six weeks following COVID, seek medical care promptly. Caught early, most children with MIS-C recover fully.

Long COVID in Young Children

Long-lasting symptoms after COVID are less common in toddlers than in older children and teens. National survey data shows that about 1% of children ages 0 to 5 have ever experienced long COVID symptoms, defined as new symptoms lasting three months or longer after infection. At any given time, only about 0.2% of that age group is actively dealing with ongoing symptoms. By comparison, teenagers are roughly twice as likely to develop long COVID. The most common lingering issues in young children tend to be fatigue, irritability, and changes in sleep or appetite. These typically resolve gradually over weeks to months.
