That depends on your child though. A child with no seizure history (febrile or otherwise) and has never had an averse reaction to a fever...most likely it's not dangerous. But there are a lot of kids where it *is* dangerous. And for very very young ones (under a year or so old) extremely high fevers can lead to a mess of problems, like brain injury. (And for pregnant women in the first trimester, high fevers can be dangerous to the unborn child as well).
So, it's not true that fevers are never dangerous. For some kids, most kids in fact, they are not. But until your child has a couple fevers, you won't know if your kid is one that it's safe to let the fevers go. It's all about knowing your child and balancing risk. There's danger in everything--you just have to konw your risk factors.
If you have a link saying that fever is dangerous in infants, could you share please?
EVERYTHING I've read says that is not true.
