I'm not sure what's going on, so was hoping someone could give me an idea....

Yesterday Zander was fine, we went out for lunch, he had a swim in our pool & was generally happy, well & everything was normal. At about 4am he had woken up & wanted a cuddle & I noticed he was hot. He went back to sleep pretty quickly then woke again at 7.30. He was still hot even though I had turned the fan on at 4am for him.

Now an hour later he has laid on the lounge or my bed & hasn't moved much. He didn't want to climb up onto my bed saying "too hard mummy" where normally he bounds up onto the bed to wake daddy up. I asked if his tummy, head, arm, leg etc etc hurt but he says nothing hurts. He doesn't have any spots or anything unusual otherwise.

So what can cause a temp (38.5) and tiredness but nothing else??
