Hello everyone! My daughter woke up this morning with a temperature of 38.3 degrees. Gave her ibuprofen, it went down. Now it's back to 38. Not lethargic, just a bit fussy, playing and crawling around. The pediatrician says it's probably on the teeth. The tip of the tooth has already come out. Everything is possible now, and that the immune system is weaker in the background, and everything can happen. She said to continue giving ibuprofen, plenty of drinking water and applying to the breast. Should I lower such a fever if the child feels normal overall and what is more effective than ibuprofen or candles?
