My 10 month olds temp is 104.8!?!

Megan

Saturday night I took him to the ER for a fever of 103.9 and he tested positive for the flu. He had surgery 5 days prior to this but surgery was minor so I wanted to be sure it wasn’t a complication. He seemed to be feeling a little better today but now his fever is back up after he slept for a little bit. Waited 10 minutes after he woke then check and it was this. Waited for another half an hour and checked again and still 104.8. Gave him more medicine but idk. He’s just watching cartoons and isn’t crying too much. Thought maybe he was over heated but we have the air at 68 and he only sleeps in a leg less and a sleeveless onesie and a sip up sleeper
