My Child Has a Fever of 103°F — What Should I Do?
- 2 days ago
- 7 min read
A high fever is one of the most stressful moments in parenting. Here's what that number actually means, what to watch for, and when it's time to seek same-day care.
It's 1am. You put your hand on your child's forehead, and it's burning. You grab the thermometer: 103.2°F. Your stomach drops.
Before you panic, take a breath. A fever of 103°F is uncomfortable and worrying, but for most children older than 3 months, it's not automatically dangerous. What matters most isn't the exact number; it's how your child looks, acts, and feels alongside that temperature.
We’ll walk you through exactly what to do, what signs mean it's time to come in for same-day care, and when a telemedicine visit with a pediatric provider might be all you need.
A fever of 103°F in a child older than 3 months is concerning but not automatically dangerous. Watch how your child looks and acts, not just the number. Signs that need same-day care include a fever that won't come down after medication, refusal to drink fluids, or a fever lasting more than 24 hours (under age 2) or 72 hours (age 2 and older). When in doubt, our pediatric team in Anchorage is available for same-day urgent care and telemedicine visits across Alaska.
What a 103°F Fever Actually Means
First, and this is important, fever is not the enemy. A fever is your child's immune system doing exactly what it's designed to do: fighting off an infection. According to the American Academy of Pediatrics, fever itself rarely causes harm in otherwise healthy children.
A fever is defined as a body temperature of 100.4°F (38°C) or above. At 103°F, your child has a high fever, but the number alone doesn't determine severity. A child with a 103°F fever who is drinking fluids, responding to you, and acting relatively like themselves is in a very different situation from a child who is limp, inconsolable, or unable to keep any fluids down.
Pediatricians use a simple rule: treat the child, not the thermometer.
Age-by-age fever guidance:
Child's Age | What to Do |
Under 3 months | Any fever of 100.4°F or higher — call or seek care right away. Do not wait. |
3–12 months | Fever of 102.2°F or higher — contact a provider. For 103°F+, same-day evaluation is recommended. |
1–3 years | Fever of 102.2°F+ that lasts more than 24 hours or is accompanied by other symptoms — seek care. |
3–12 years | Fever of 103°F+ that doesn't respond to medication, lasts more than 72 hours, or comes with concerning symptoms — see a provider. |
12+ years | Same guidance as older children. If the fever reaches 104°F+ or won't come down, seek same-day care. |

Signs That Mean Your Child Needs Same-Day Care
This is the list to bookmark. If your child has a fever of 103°F and any of the following signs are present, it's time to be seen by a pediatric provider today, either in person at our Anchorage clinic or via telemedicine if you're elsewhere in Alaska.
Seek same-day pediatric care if your child:
Is under 3 months old and has any fever at all
Has a fever that doesn't decrease by 1–2 degrees after giving a weight-appropriate dose of acetaminophen or ibuprofen
Refuses to drink fluids or shows signs of dehydration (no tears when crying, fewer wet diapers than usual, dry mouth)
Has had a fever for more than 24 hours (children under 2) or more than 72 hours (children over 2)
Has a fever along with a stiff neck, severe headache, sensitivity to light, or a rash
Is unusually difficult to wake, extremely lethargic, or inconsolable
Has a fever paired with ear pain, sore throat, or other symptoms that suggest a bacterial infection needing treatment
Has a chronic health condition, the threshold for seeking care is lower for children with underlying medical issues
Is your child showing any of these signs right now?
We offer same-day pediatric urgent care in Anchorage. No long ER wait, and a team that specializes specifically in children. You can also start a telemedicine visit from anywhere in Alaska, available daily from 8am to
midnight.
When You Can Manage a 103°F Fever at Home
Not every 103°F fever requires an immediate visit. If your child is older than 3 months, has no other concerning symptoms, and is still alert, drinking fluids, and responsive, there's a good chance you can manage comfortably at home while keeping a close eye on things.
Here's how to keep your child comfortable:
Give acetaminophen (Tylenol) or ibuprofen — dosed by weight, not age. Always follow the package instructions. Avoid aspirin in children, as it is associated with a rare but serious condition called Reye's syndrome.
Keep fluids coming. Fever causes kids to lose fluid faster than normal. Water, electrolyte drinks, ice pops, broth, and diluted juice are all good options. Offer small amounts frequently if your child isn't interested in drinking.
Dress them lightly. Heavy blankets and warm clothing trap heat. Lightweight layers allow the body to regulate temperature more effectively.
A lukewarm bath can help with comfort — not cold water, which can cause shivering and drive the temperature up.
Let them rest. Sleep is when the immune system does its best work.
One more thing worth knowing: you don't have to bring the fever all the way to normal to feel reassured. If your child's temperature drops by even 1–2 degrees after medication and they perk up and start acting more like themselves, that's a good sign their body is responding well.
What to Expect at Pediatric Urgent Care for a Fever
If you decide it's time to come in or you're not sure and want a professional opinion, here's what a visit with us in Anchorage looks like. Knowing what to expect often makes the decision to come in easier.
Check-in: You can book online in advance to reserve your spot. Same-day and walk-in appointments are available starting at 11am. Patients with appointments are seen first, so online booking means less wait time.
Assessment: A pediatric provider will take your child's temperature, check their ears, throat, and lymph nodes, and ask about symptoms and duration. We look at the whole picture — not just the fever number.
Testing if needed: If strep throat, flu, RSV, or a urinary tract infection is suspected, a quick in-office test can confirm or rule it out on the spot.
Treatment plan: If a bacterial infection is found, we'll prescribe antibiotics. If it's viral, we'll walk you through fever management and what to watch for over the next 24–48 hours.
Follow-up guidance: You'll leave with a clear picture of what's going on and exactly when to come back if things change.
Our Anchorage clinic is designed for children, the environment, the approach, and every provider on our team. We're not a general urgent care that happens to see kids. Pediatrics is all we do.
Can I Use Telemedicine for My Child's Fever?
Yes, in many cases, a telemedicine visit is a great first step. We offer pediatric telemedicine daily from 8am to midnight, available to families anywhere in Alaska.
Telemedicine works well for fever when:
Your child is older than 3 months and doesn't have any of the red-flag symptoms listed above
You want a pediatric provider to evaluate symptoms and give guidance before deciding whether an in-person visit is needed
It's late at night or you're in a community outside Anchorage, like the Mat-Su Valley, Fairbanks, or a rural area, where getting to a clinic isn't easy
You need guidance on medication dosing, home care, or how long to monitor the fever before acting
During a telemedicine visit, our provider will talk through your child's symptoms, history, and current condition. They may ask you to check the throat with a flashlight, feel the lymph nodes, or describe the rash if there is one. Based on what they see and hear, they'll tell you whether to manage at home or come in and they can send prescriptions to your pharmacy electronically if needed.
Telemedicine won't replace an in-person visit for a very sick child, but it's a powerful tool for getting a pediatric opinion fast, especially when you're trying to decide if 103°F is serious enough to warrant a same-day trip.

Frequently Asked Questions
Is 103°F a dangerous fever for a child?
A fever of 103°F is high, but for most children older than 3 months, it is not automatically dangerous. The more important factors are your child's age, how they are acting, and whether the fever responds to medication. A child who is alert, drinking fluids, and responding to you is in a very different situation from one who is lethargic or inconsolable. If you're unsure, a telemedicine visit with a pediatric provider is a fast way to get a professional opinion.
How long can a child have a 103°F fever before going to the doctor?
For children under age 2, seek care if a fever lasts more than 24 hours. For children over age 2, the general guideline is 72 hours, but don't wait that long if other concerning symptoms develop (refusal to drink, extreme fatigue, a rash, ear pain, or a fever that won't respond to medication). When in doubt, call or come in.
What do I do if my child's fever won't come down?
If your child's temperature doesn't drop by at least 1–2 degrees after giving the correct weight-based dose of acetaminophen or ibuprofen, that's a sign they need to be evaluated. Make sure you're dosing by weight and not by age, the package instructions have weight-based charts. If the fever still doesn't respond, seek same-day care. Alaska Children's is available for walk-in and same-day urgent care in Anchorage, and via telemedicine statewide.
Should I take my child to urgent care or the ER for a high fever?
For most fevers, including 103°F, pediatric urgent care is the right choice. It's faster than an ER, staffed by pediatric specialists, and designed for exactly this kind of situation. Head directly to an emergency department (or call 911) only if your child is having extreme difficulty breathing, is unconscious or unresponsive, or is under 28 days old with any fever. For everything else, Alaska Children's same-day urgent care is built for you.
Can I use telemedicine for my child's fever?
Yes, Alaska Children's offers pediatric telemedicine daily from 8am to midnight, statewide. If your child is over 3 months old and not showing severe symptoms, a telemedicine visit is an excellent way to get a fast pediatric assessment and decide on next steps without leaving home.
