Understanding fever seizures in children

A febrile seizure is a seizure that happens with a fever, usually in babies and young children. For many families, a child fever seizure is sudden and frightening, especially the first time. While many febrile seizures are brief and stop on their own, it is still important to know what fever seizure symptoms in children can look like, how long febrile seizures last, and when emergency care is needed. This page is designed to help parents understand what may be happening and what to do during a febrile seizure.

What a febrile seizure may look like

Body stiffening or shaking

A child may lose awareness, stiffen, jerk, or shake during a fever seizure in child. Some children also roll their eyes or seem unresponsive for a short time.

Brief sleepiness afterward

After a child fever seizure, it is common for a child to be sleepy, confused, or less alert for a little while as they recover.

Happens with a fever

A febrile seizure in toddler or baby often happens when a fever rises quickly, sometimes before a parent even realizes the child is sick.

What to do during a febrile seizure

Keep your child safe

Place your child on their side on a flat surface and move nearby objects away. Do not hold them down and do not put anything in their mouth.

Watch the time

If you are wondering how long do febrile seizures last, many are short, but timing the episode matters. Knowing whether it lasted 1 minute or more than 5 minutes helps guide next steps.

Notice breathing and recovery

Look for normal breathing, skin color, and how your child acts after the seizure stops. These details can help you decide when to call 911 for febrile seizure concerns.

When to get urgent help

Call 911 if the seizure lasts more than 5 minutes

Emergency care is important if the seizure does not stop quickly, your child has trouble breathing, or they do not start waking up afterward.

Get urgent care for a first febrile seizure in child

A first febrile seizure in child should be medically evaluated, even if your child seems better afterward, to help confirm the cause and rule out other concerns.

Seek help for unusual symptoms

Call for urgent medical care if only one side of the body is shaking, your child is younger than 6 months, has a stiff neck, repeated vomiting, severe lethargy, or another seizure the same day.

Why personalized guidance can help

Parents often search can fever cause seizures in children because the event is so alarming and hard to interpret in the moment. The right next step depends on what you saw, how old your child is, how high the fever is, how long the episode lasted, and whether this was the first time. A short assessment can help you sort through those details and understand whether home monitoring, same-day medical care, or emergency help makes the most sense.
