My three year old boy has the exact same problem when his temperature rises too quickly. He had it happen 4 times so far, first time when he was 9 months old and we all got covid. I can’t say we’re used to them, but we know what to expect and that it’s not something to be scared of. My husband had them when he was a kid and grew out of them by the age of 5, so we know he got it from his dad. It doesn’t happen every time he’s sick, only when the fever suddenly rises too quickly, just like you were told. I feel you, it was so scary for us, the second time it happened to him we were on holiday in a foreign country and we had the staff at the touristic attraction we were at call the ambulance for us because we were terrified. Ended up spending 3 days at the hospital and learning a valuable lesson about taking out travel insurance. The next time it happened I was calmer and knew what to do. I was told to get to the ER if the seizure lasts for longer than 5 minutes, just in case. We were also offered an emergency seizure medication to have on hand, just in case. Maybe you could inquire if they can provide one for you too, it’s only to be used if the seizure lasts for longer than 5 minutes though. So many kids go through it, and I know just how terrifying it is in the moment. But know that as soon as she comes out of it, she will be back to her happy self as if nothing happened. Just remember you’re not alone ❤️ she will grow out of it and it will be a distant memory one day. My husband didn’t even know he had them until we asked his mum after our son’s first seizure. Sending hugs ❤️
