My DS4 is nearly four years old and has been unwell tonight. He went straight to sleep at 7 and looked glassy eyed so I took his temp and he was 37.5. An hour later I checked him again and he was still warm but sleeping.

Around 9 we heard laughing coming from his room and went down to find him giggling and saying 'that's funny' over and over. He was starring blankly at his wall and was drooling too. We couldn't get him stones nap out if it for a while. I lifted him up and felt the heat radiating off him and thermometer said 39 degrees.

I carried him out to the kitchen and it wasn't till probably 5 or 6 minutes that he fully came back and was able to answer question.

About another half hour later we were finally able to convince him to take some panadol and then put him back to bed and within five minute he vomited.

I keep checking him and he seems ok. Temp around 37.5 but sleeping soundly. I wouldn't have thought his fever was high enough to cause delirium or hallucinations. Assuming he's ok in the morning would you take him to get checked out or not worry? Anyone else experienced anything like this?
