3. 2 year old daughter have Fever. Do.

My 3.2 year old daughter, weight 12.5 kg, has fever since five days. We brought her to a Child specialist and he has prescribed ibugesic plus  (6 ml 3 dose daily) plus & Zifi 100  (3 ml 2 dose daily). Her temperature becomes normal for 6 to 7 hours after giving ibugesic however it raises after 6 hours upto 103.5F or 104 F specially at night b/w 2AM to 5 AM. Previously this was 4 to 5 hours . When we give her sponge and ibugesic then fever comes down to normal b/w 97.5 to 98.6. She has no cough and not flowing nose and no rashes on body but she is showing less appetite however we are able to feed her a half chapati, boiled egg,milk, biscuits, readymade apple juice. Doctor has told us to do some blood test such as CVC, Malleria, Typhoid after 5 days if fever is not in control. Please advice what to do.
