as a rule of thumb once a temp gets to 39 its straight to the dr or hospital as once babies get close to 40 there is a chance of fitting.

panadol is good, but masks alot of things and will last longer the more doses she has.

there has been alot of bugs going around with babies lately, my DD has foot hand and mouth and nothing shows up till after the high temps runny poo and vomiting then they get better andbam blisters and rash.
its great being a parent lol..
This is one of the reasons many childcare and kindys will not give panadol anylonger - it can hide the symptoms of much worse things.
That said, it would be far worse to have a child fit because of a temp, get her checked for peace of mind - the doc will probably say give her panadol!
