While the list of illnesses that can afflict a child is lengthy, reasons for seeking medical attention in the middle of the night are few. They also make good sense. Febrile seizures are not the result of especially high fever.
Doctor say febrile seizures are harmless in themselves, but they scare parents witless.
Get the child on the floor so she will not fall off the bed. Roll her on her side so she will not choke. Clear the immediate area of anything that might injure her, and call the pediatrician. Try not to leave her alone. Times like this are when cordless phones are worth their weight in gold.
