When a Febrile Seizure Isn't Just a Febrile Seizure

The Weight of Uncertainty

When my daughter Olive was just 18 months old, she experienced what doctors initially called a febrile seizure—a common occurrence in young children triggered by fever or a rapid rise in body temperature. At the time, I thought we were safe. The pediatrician reassured us that such seizures are typically harmless and not linked to long-term complications. We were told everything was fine. That night, she was gone.

"She was just truly a ray of light," I said. "She was such an easy, calm baby, and then she turned one. She had the best personality, and was always going, doing, learning something."

That was Olive. She was a child who lived with intensity, full of joy and curiosity. She loved water, approached strangers like old friends, and had an infectious laugh that could light up any room. Her parents, David and I, knew we were lucky to have her in our lives.

Two Close Calls

But then came the first red flag. It was July 4th on vacation in California when Olive had fallen asleep in her aunt's arms after a day at the beach. Something didn't feel right. Her lips turned blue, and despite quick action—water poured on her head, and someone patted her back—she recovered quickly. By morning, she was acting normal again.

We were told by urgent care that dehydration was likely to blame. The pediatrician confirmed the diagnosis, suggesting a febrile seizure was possible but not dangerous. It wasn't until months later that I began to suspect something more.

Then came another episode on September 2nd. This time, Olive was in her car seat during our family dinner. As I drove, I felt an instinctive need to check on her. In the rearview mirror, she was seizing. I pulled over immediately and called for help. At the hospital, doctors found a slight fever—but no clear cause for concern.

We left the ER with the same message: nothing more than a febrile seizure. We were told to watch carefully, monitor her temperature, and trust that these incidents wouldn't happen again. But I couldn't shake the feeling that there was more to Olive's story.

The Moment Everything Changed

On November 1st, 2023, it happened again—but this time, it was final. David had gone to check on Olive before bed and found her not breathing. I was coaching volleyball at the time, but as soon as he called, my heart dropped. There's no way you can prepare for that kind of reality.

I rushed to the hospital where doctors were still trying to save her. I remember looking down at her face and seeing no movement. No pulse. Nothing. We lost her in those moments. There was nothing more we could do. I stood beside her lifeless body, holding onto what felt like a dream that had ended too soon.

It wasn't until later that we learned the cause of death was inconclusive—though a subsequent autopsy did not reveal any signs of illness or trauma. This left us with a haunting silence: a child gone without explanation.

Looking Back for Answers

As time passed, David and I found ourselves searching online, learning about Sudden Unexplained Death in Childhood (SUDC). This rare condition affects children who appear healthy before dying suddenly and unexpectedly with no known cause even after thorough investigation. While some studies, such as one published in Neurology by NYU Grossman School of Medicine, have suggested a possible connection between SUDC and febrile seizures, not all children who experience them go on to develop serious complications.

This is where the weight of uncertainty hits hardest. How do you move forward when your child's death is so ambiguous? When the medical system can't offer clarity, but still offers comfort?

"I don't want people to live in fear," I said in an effort to keep Olive's memory alive. "Her story is not to scare people. It's just to shed light and I just want there to be awareness."

I share her story now on TikTok (@aubreytenney), hoping that other families might recognize warning signs early, and that medical professionals will take notice when multiple febrile seizure events occur in close succession.

Living With Memory

Today, we celebrate Olive's life each year. On her birthday, we eat edamame, wear olive green, and remember the little girl whose light still shines brightly in our hearts. We have olive trees everywhere—my curtains are olive; everything about me is olive now.

My twins know about her; we say her name. She is everywhere. We've learned that grief isn't something you get over—it's something you carry with pride, love, and hope. Olive's legacy lives on not in what she didn't get to do, but in how deeply she touched the lives around her.

What This Means for Parents

This is why I feel compelled to speak publicly about this experience: it's not just about one family's pain—it's a call to action. Medical professionals, parents, and caregivers must remain vigilant, especially when dealing with febrile seizures that happen more than once.

The truth is, sometimes the safest-looking moments hide the most dangerous truths. And while we may never fully understand why Olive left us, I hope sharing her story helps others be better prepared, watchful, and informed.

• Febrile seizures, while common, should not be dismissed lightly if they occur repeatedly
• Parents should consider seeking further neurological evaluation if there are multiple episodes
• Supporting research into SUDC remains critical to understanding sudden unexplained childhood deaths

In the end, Olive didn't die from a lack of care or attention. She died because her body gave up under circumstances that science still struggles to fully explain. But in the wake of such loss, we can honor her memory by making sure others don't suffer in silence.
