Franklymydear is right: if temp not going down, you can alternate calpol and ibuprofen as they're very different drugs. Basically, keep giving calpol with the recommended time gaps in between each dose and do the same with ibuprofen. One is 3, the other 4 hours, I think, but you need to check with each. this should definitely bring the temp down.
calprofen is ibuprofen. It is the name the manufacturers give it as they also make calpol but calprofen is ibuprofen and calpol is paracetamol, so you can give both at the same time.
One of my children spiked a high temperature after his MMR (presume that is the jab you mean). It went above 40. Try not to panic and keep up the meds, a lukewarm flannel on face and wrists maybe, and no clothes.
If she wants Milk thats ok,but still give water or squash,as this will help bring the temp down,but milk wont.
Usual advice is an hour after Calpol.But my DS was given them simultaneously in A&E,so although its preferred nowadays to give them an hour apart,theres no real danger,except it can make them very drowsy.
So now would be good,should see a more effective lowering of temp hopefully.
If you are worried about during the night,I used to make a bed up next to my DC's so i could check on them,or set your alarm for 3.30am to check her.
you can only give paracetamol four times a day and ibuprofen 3 times a day. But the ibuprofen must be with food,not on an empty stomach.high temperatures are more dangerous when they spike, I was told that a constantly high temperature is not as much of a concern as one that jumps up and down. careful how much ibuprofen you give as it can strip the bowel in such a young baby
