At 40.5deg I called the hospital & they said to take him in. When we got in there it was very cool & he started to cool down & come back round a bit, before that he was very sleepy & wasn't moving much. The triage nurse checked him out & his temp just from going into the cool waiting room had dropped to 38.5 so I think it might just be the heat. She noticed some spots on his legs, back & behind his ear that might possibly be chicken pox because it's going round here at the moment....... She said it might not be but to keep an eye on them. We managed to get some panadol into him & he seems his normal self now 1/2 an hour later.
