actually there is no point bringing your child to Kandang Kerbau Hospital.
fever with no cause (e.g. flu, diarrhea) is a concern. But since your child has cough/ rn, at least we know the fever is caused by the flu bug.
when to worry? when your child is lethargic, refused feeds, concentrated urine (signs of dehydration), keep sleeping, etc.
on and off fever means the body is trying to fight the bug. sometimes win, sometimes lose. the fever will continue to fluctuate for a few days. you just have to keep monitoring the temperature and feed fever medicine when needed. try to offer your child different types of fluid as our body's temperature also depends on the amount of water inside. sponging your child is also very important when the temperature goes up. anywhere on forehead, hands, armpits, back of neck & groin. must also bath your child in normal temp or slightly warm water - but a quick one. faster bath and dry.
oh ya, and dont be too quick to let your child depend on anti-biotics. I notice many parents asking for anti-biotics as soon as they worry. Let your child's immune system try to fight first. usually after 3 days, then perhaps you may consult the doc for anti-biotics. hope this helps.
