The information in this article is for educational purposes only and does not constitute medical advice. Always consult your child’s doctor before making any health decisions. If your child is having a medical emergency, difficulty breathing, a seizure lasting more than 5 minutes, unresponsiveness, call 911 immediately.
Watching your child have a seizure is one of the most frightening things a parent can witness. If it happened alongside a fever, what you likely saw was a febrile seizure, a seizure triggered by a fever in a young child, most often between 6 months and 5 years of age. A child may stiffen, shake, roll their eyes back, or become unresponsive for a short time.
Here is the steady truth: most febrile seizures are brief, stop on their own, and cause no lasting harm. Having one does not mean your child has epilepsy. Seizures and epilepsy are related but different things, and a single fever-triggered seizure sits firmly in the first category for most children. That said, "most" is not "all," and knowing the difference matters.
This article, written by Dr. Shawn Sedgh, MD, walks you through three questions every parent deserves clear answers to. First, what am I actually seeing, what does a febrile seizure look like? Second, what do I do right now, in the moment, while it's happening? Third, when do I call 911, specifically, when a seizure lasts more than 5 minutes, your child has trouble breathing, or they don't wake up as expected afterward.
Let's take these one at a time.
What a Febrile Seizure Looks Like: What You May See
A febrile seizure is a seizure that happens with a fever, usually in children between 6 months and 5 years old. It can be frightening to watch, but knowing what to expect helps you stay calm and describe it clearly afterward.
During the seizure, you may see your child's arms and legs shaking rhythmically, or their body may suddenly stiffen. Their eyes might roll back or stare blankly, and they won't respond when you call their name or touch them. Some children drool, breathe irregularly, or briefly turn pale or bluish around the lips. Most episodes stop on their own within a few minutes. Afterward, it's very common for a child to be sleepy, confused, or fussy, this "post-seizure fog" can last from minutes to an hour.
Dr. Shawn Sedgh, MD, encourages parents to time the seizure and note what they saw, since those details help the doctor sort out what happened.
Doctors generally group febrile seizures into two types. A simple febrile seizure lasts under 15 minutes, affects the whole body, and happens only once in 24 hours. A complex one lasts longer, repeats within a day, or involves just one side of the body.
Call 911 if a seizure lasts more than 5 minutes, if your child has trouble breathing, or if they remain unresponsive afterward. Learning about seizures and epilepsy can feel overwhelming, but most febrile seizures are brief and don't cause lasting harm.
What to Do During a Febrile Seizure: Step-by-Step
Watching your child have a seizure is frightening. Knowing the steps ahead of time helps you act with confidence. Here's what Dr. Shawn Sedgh, MD, author of SimplyPedsNeuro, wants parents to know.
1. Stay calm. Easier said than done, but your child needs you present, not panicking. Most febrile seizures stop on their own within a few minutes.
2. Time the seizure. Look at a clock or start a timer on your phone. This single detail matters enormously when you talk to a doctor later.
3. Move your child to a safe, flat surface. Gently place them on their side on the floor or a firm bed, away from hard furniture, stairs, or sharp corners.
4. Loosen tight clothing around the neck so breathing stays easy.
5. Never put anything in your child's mouth. No spoon, no fingers, nothing. And never try to hold them still or restrain their movements, you could cause an injury.
Call 911 right away if the seizure lasts more than 5 minutes, if your child has trouble breathing, turns blue, or doesn't wake up and respond normally after it ends.
Once the shaking stops: Keep your child on their side. Let them rest. They may be sleepy or confused for a little while, that's common. Give the fever time to be addressed per your pediatrician's guidance, and call your doctor the same day. A first febrile seizure always deserves medical evaluation, even a brief one.
One seizure doesn't mean epilepsy. Seizures and epilepsy are related but different, and most children who have a febrile seizure never have another. Your pediatrician can help you understand what comes next for your child.
When to Call 911: Red Flags You Should Never Ignore
Most febrile seizures stop on their own within a couple of minutes and do not cause lasting harm. Even so, some situations are true emergencies. As Dr. Shawn Sedgh, MD, notes, knowing these red flags ahead of time helps parents act quickly instead of freezing in the moment.
Call 911 right away if:
- The seizure lasts more than 5 minutes. Time it if you can. A seizure that passes the five-minute mark needs emergency treatment to stop it safely.
- Your child has trouble breathing or turns bluish, especially around the lips or face, and it does not resolve as the seizure ends.
- Your child stays unresponsive afterward. It is normal for a child to be sleepy or confused for a short while after a seizure. But if your child does not gradually wake up, or you cannot rouse them at all, that is an emergency.
- A second seizure happens shortly after the first, before your child has fully recovered.
- It is a first-ever seizure and you are unsure what is happening. If you do not know whether it is a febrile seizure, breathing problem, choking, or something else, call. It is always okay to be wrong in the direction of caution.
When the dispatcher answers, stay calm and say: "My child is having a seizure." Give your child's age, how long the seizure has lasted, whether they are breathing, and whether they have had seizures before. Stay on the line and follow their instructions. Topics like these sit at the heart of Seizures and epilepsy care, and no parent should hesitate to call for help.
Does a Febrile Seizure Mean Epilepsy?
If your child just had a febrile seizure, this is probably the question keeping you up at night. Here's the honest answer from Dr. Shawn Sedgh, MD: in most cases, no.
A febrile seizure is a seizure that happens with a fever in a young child, most often between 6 months and 5 years old. During one, you might see your child stiffen, shake on both sides of the body, roll their eyes back, or become unresponsive for a short time. It looks frightening. Most stop on their own within a couple of minutes, and most children who have one never develop epilepsy.
Parents reading about Seizures and epilepsy should understand the key difference: epilepsy means repeated seizures *without* a fever or other clear trigger. A febrile seizure is tied to the fever itself. One doesn't automatically become the other.
Some children do have another febrile seizure with a future illness, recurrence happens, and it still doesn't mean epilepsy. What *does* prompt further evaluation? A seizure that lasts a long time, one that affects only one side of the body, more than one seizure within 24 hours, a child under 12 months, or a child who isn't back to their usual self afterward. Those situations deserve a closer look, often including a conversation with a pediatric neurologist.
In the moment: lay your child on their side on a safe surface, don't put anything in their mouth, and time the seizure. Call 911 if it lasts more than 5 minutes, if your child has trouble breathing, or if they don't wake up afterward.
After the Seizure: Follow-Up Care and What to Tell Your Doctor
Any child who has a first febrile seizure should see a pediatrician afterward, even if they seem completely back to normal. If the seizure stopped on its own within a few minutes and your child recovered fully, a prompt appointment, usually within a day or two, is appropriate. Call 911 instead if a seizure lasts more than 5 minutes, if your child has trouble breathing, or if they don't wake up and respond normally. Seizures that keep coming back, or one-sided shaking, also warrant urgent evaluation.
Before the visit, jot down a few details while they're fresh:
- How long the seizure lasted, as best you can estimate
- What it looked like, stiffening, jerking, eye rolling, whether both sides of the body were involved
- How high the fever was and when it started
- How quickly your child returned to their usual self
A short phone video, if you happen to have one, can be genuinely helpful for the doctor.
This information helps your pediatrician distinguish a simple febrile seizure from something that needs more testing. Dr. Shawn Sedgh, MD notes that parents often worry about Seizures and epilepsy, but most febrile seizures in young children are isolated events tied to the illness itself.
Going forward, fevers are managed the usual way: keep your child comfortable, offer fluids, and treat the illness, not the fear of another seizure. Your pediatrician can walk you through what to watch for with future fevers.
Next Step: Getting Answers and Peace of Mind
The most important thing to remember: most febrile seizures last only a minute or two and don't cause lasting harm. As Dr. Shawn Sedgh, MD explains, the red flags that warrant a 911 call are a seizure lasting more than 5 minutes, trouble breathing, or a child who isn't waking up afterward. Knowing those signs ahead of time helps you stay calm when it matters most.
Even so, any first seizure deserves a pediatric evaluation. Your doctor can confirm the fever's source, rule out other causes, and talk through your child's recurrence risk and whether conditions like Seizures and epilepsy need to be considered. That conversation turns a frightening moment into a clear plan for the future.
You don't have to carry the worry alone. If febrile seizures keep happening, or something about your child's episodes doesn't sit right with you, trust that instinct.
