Looking for some advice, my sons temp has been over 40 since getting home from nursery yesterday, he had some calpol when he got home and his temp went down but all night it’s been spiking back up again. What would you do? Would you ring 111? At one point it was 40.6 and his breathing was fast. He had his injections a week ago, is it something to do with that? I’ve just checked his temp now and it’s 40.2 :(
