Febrile convulsion in a four year old?

Hi.
My DS had three febrile convulsions at the age of 8 months (one, then two the next day, so part of the same illness) then one convulsion just before he turned two. All while he had very high temperatures.
I thought we were past it, but then he had another one this weekend, again with a very high temperature which he’d had all day.
My question is, has anyone else’s child had a FC so late in childhood and been okay?
Is this a sign of something else, or is the fact that its temperature-related every time mean that its okay?
How on earth can I prevent them in the future? We gave him calpol all day every four hours and that clearly didn’t ward it off at all.
Very worried and scared to leave him alone. Will this happen every time he has a temperature? He’s had numerous illnesses with fevers one year old to now and it hasn’t happened. Thanks. Any advice or your own experiences appreciated.

Febrile convulsions are usually related to how quickly the temperature rises not how high it gets so it's possible that he's had typical fevers over the year but none that rose rapidly enough to cause a seizure except on this occasion.

DD had 6 febrile seizures her last one at aged 5. She has been absolutely fine since. No epilepsy. DD is late teens now.

Aas @Realisation14 says it's the Change in temp rather than the actual temperature itself. Once you've had one you are much more likely to have nore

My 2 year old has had multiple (all with a high temp). She is under a consultant due to how many, but so far it is nothing more than febrile. They say they grow out of the. By age 5-6 and then if older or without a temperature will look into something else e.g. epilepsy. Apparently it's common in young children.

It's super scary though and I totally understand your worries about leaving him alone, but usually it is when they are under the weather anyway so make sure you stay nearby and also let any childcare settings know.

You can’t prevent them. It’s related to the temperature rising rather than how high it gets. We all have a ceiling with how our body tolerates a temperature and for some that’s having a seizure. Giving calpol isn’t thought to make any difference. But generally febrile convulsions are thought to be til around 5 years old.

Just to add you can only give calpol 4 times in 24 hours, not every four hours continually.
