If your baby had a febrile seizure, you are likely looking for clear next steps, common symptoms, how long episodes usually last, and when emergency care is needed. Get calm, expert-backed guidance tailored to your infant’s age and what happened.
Tell us whether your infant had a febrile seizure today, in the past few days, or if you are worried one may be happening now. We’ll help you understand what to do next, what symptoms matter most, and when to call 911.
An infant febrile seizure is a seizure that happens with a fever, usually during a common illness such as a viral infection. For many parents, the first febrile seizure in a baby is frightening because it can happen suddenly, even when the fever did not seem very high yet. Febrile seizures are most common in young children, and babies may have shaking, stiffening, eye rolling, or brief unresponsiveness. While many febrile seizures are short and stop on their own, it is important to know what happened, how long it lasted, your baby’s age, and whether there are any warning signs that need urgent medical care.
A baby may have rhythmic shaking of the arms and legs, or the body may stiffen before jerking starts. This is one of the most common signs parents describe when they say their baby had a febrile seizure.
Your infant may not respond to your voice, may stare, or may seem unusually limp or still during the episode. Some babies appear sleepy or confused for a short time afterward.
A febrile seizure in a baby often happens when a fever is rising quickly. Parents may notice warmth, fussiness, sleepiness, or signs of a cold or other illness before the seizure begins.
Place your baby on a safe surface, ideally on their side, and move away nearby objects. Do not put anything in your baby’s mouth and do not try to hold their body still.
Try to time how long the seizure lasts and note what you saw, such as shaking, stiffening, color change, or trouble breathing. This information helps a clinician understand what happened.
If you are worried your baby may be having one now, if the seizure lasts several minutes, if breathing seems abnormal, or if your infant is very young or not recovering as expected, seek urgent care right away.
Call 911 if the seizure does not stop within 5 minutes, or if repeated seizures happen close together without your baby returning to normal in between.
Emergency help is needed if your infant is struggling to breathe, turns blue or gray, or remains hard to wake after the episode.
Call 911 if your baby is under 6 months, has a seizure without a fever, has a serious injury, has a stiff neck, or looks severely ill. Trust your instincts if something feels wrong.
Many febrile seizures are brief and last only a few minutes, though even a short episode can feel much longer to a parent. A febrile seizure in a 6 month old or a febrile seizure in a 1 year old may still need prompt medical review, especially if it is the first episode. Some babies will never have another seizure, while others may have a recurrence with future fevers. Risk can depend on age, family history, how early the seizure happened in the illness, and whether the fever was rising quickly. Personalized guidance can help you understand what is more likely in your baby’s situation and what steps to take during future fevers.
Make sure your baby is in a safe position, preferably on their side, and time the episode. Do not put anything in their mouth. If the seizure lasts 5 minutes or more, your baby has trouble breathing, or recovery seems unusual, call 911. Even when the seizure is brief, contact a medical professional for guidance, especially if this was the first febrile seizure in your baby.
Many febrile seizures are short and last a few minutes. If a seizure lasts 5 minutes or longer, emergency care is important. Timing the event as closely as you can is one of the most helpful details to share with a clinician.
Common symptoms include shaking or jerking, body stiffening, eye rolling, loss of awareness, limpness, and sleepiness afterward, along with a fever. Some babies may seem confused or unusually tired for a short time after the seizure ends.
Age matters when deciding how urgently a baby should be evaluated. A febrile seizure in a 6 month old may raise different questions than one in a 1 year old because younger infants can need closer assessment. The baby’s age, fever, symptoms, and recovery all help guide next steps.
Call 911 if the seizure lasts 5 minutes or more, your baby has trouble breathing, turns blue or gray, has repeated seizures, is hard to wake, is under 6 months, or looks seriously ill. If you are not sure whether what you saw was a febrile seizure and your baby seems unwell, urgent help is appropriate.
Answer a few questions about your infant’s age, fever, symptoms, and what happened during the episode to get a clearer sense of next steps, when urgent care may be needed, and what to watch for going forward.
