Alamak, sounds like a rough few days for your little one! But ya, measles symptoms are very clear-cut macam yang u list, demam naik turun, cranky, then the rash comes later. Pls do get to a clinic or doc asap to confirm and get proper care, especially kena monitor closely ya, better safe than sorry with something like this. A few of my mum friends' kids went through the same, and paracetamol + rest + lots of fluids helped jaga daya tahan sampai the worst passed. Memang kena sabar je, tak ada shortcut. How's she eating and drinking now?
