I just went hunting through our magnet collection and found an old one for westmead childrens when we lived in Sydney - they had a sick kids helpline (02) 9845 2432 - it doesn't say whether it was 24hrs and won't be toll free from where you are but don't be afraid to use it if you need some reassurance. I tend to agree with Renstar though if you can keep up fluids (offer every 15 to 20 mins while awake) or watery iceblocks and some exterior cooling to the affected areas he will know doubt be fine but I do know how worried we get about unwell kids so :hugs: and thoughts to you tonight.

If you have an aircondtioned room (not too cold) I'd consider sleeping him in their to keep his body temperature down and minimise the sweating and burning.
