question: my child has had fever for the past 3 days with temp as high as 40.4...after giving ibuprofen it does go down to 37 and go up back to 39+.What worries me is he has been mostly sleeping the past 24 hours...only waking up for about 5-10 minutes and then sleeping again.He is 3 years old.He just take sips of water in between and ate very little.
