My 1 year old DS just woke up with a fever. 38.8. The heating was playing up, so the room was really really hot. Could that have caused the fever ? We will all get tested etc as we should tomorrow, but just wondering if a hot room and overheating can cause fevers ? I've not stripped him down, given him milk and gone to a cool room. He had loads of milk, Calpol and is now sleeping. His fever went down. I'm keeping him fresher with not too many layers. Just a baby grow.
