Your concerns are valid and can be related to.
The ceiling dose for paracetamol is 60 mg/kg/day. Less than theta dose is unlikely to cause any harm. Regarding the long term side effects of paracetamol on prolonged use, there is no definitive data regarding documented serious adverse events in children. But, there have been occasional reports of long term cardiovascular, renal side effects. Hence caution is advised.
It is better to avoid drugs as far as possible. Over-the-counter use of drugs needs to be avoided. Fever causes great distress to parents and is often aggressively countered with medications. Fever is a protective response of the body in response to infection. Fever has to be treated only if it causes distress to the child. Hence, my general advice would be to avoid self-medication.
