My son had the same high fever a couple months ago. He had it for like 3-4 days and went away on its own. But a couple days after that I noticed he was getting spots all over his face and body. We went to the doctor and turned out the fever and spots was because he had strep throat. Go to his pediatrician just to see exactly what it can be. But if he just has a high fever after getting the chicken pox vaccine that can be the cause too.

Cool Bath and maybe just a diaper on after..warm blankets keep the fever in

Hey I worked in the ER & 100.4 to them is not considered a high fever but if it goes back up to at least 101 definitely bring him in.

@raisingabi, I checked it at 5:45am it was 100.4 if it still doesn't go down back to normal then I will take him to the Dr

I would take him to the Dr. That's really high.

Time to visit the doctor
