Hello, what can be done to bring down the child's temperature? It started at 8 am with a fever of 37 and then it was 9. Then she took Ibuprofen and only after two hours it went down and now, after about 8 hours, there is another fever, but only higher than 38 and 8. Could this be due to meningitis? Although almost everything has passed here ? I'm worried very much.
