Recurrent fever after every 6-7 hours.

Dr. My 14 month old girl is getting fever 101-103 deg F since yesterday evening all of a sudden. I am giving her crocin drops 1 ml each time and fever subsides but again after around 6-7 hrs. It comes back. She has watery eyes also during fever. Is there any serious problem? Should i continue with crocin drops each time fever shoots up as its been 4-5 times since yesterday that i gave her each time. Is it safe? Her activities are nearly normal when fever subsides though still not the regular intensity. But during fever she is very low. I am very worried as this is second day and no signs of improvement. This has happened for the first time. Her weight is nearly 7.5 kg and birth weight being 2.4 kg. Please suggest something.
