My 10year old hasn’t been right today, sort of normal this morning and we went to a trampoline park and had some lunch etc but I started to notice he was a bit off and quiet, by 6pm he’s hugging himself and saying he’s really cold and just seemingly generally unwell, says his head hurts and his throat, put vapour stuff in his bath and got him to drink a bit more, Then I found him asleep, fallen asleep with earphones on watching YouTube which is absolutely in heard of, just been in to check on him and he’s really hot to the touch, temperate is 40c - I don’t know wether I’m being ridiculous but it’s made me realise he’s never really ill so it’s all a bit surprising and I don’t want to ignore it and regret it....any advice?!
