Biogesic 0-2 years for 4 months old

Hello mga mommies. My 4 month old baby got vaccinated and as a side effect, nilalagnat ung baby ko. I just want to clarify the dosage dun sa mga nagpapainom ng biogesic for kids. Nakalagay kasi na 0.6ml to 1ml ang 4-6 months. So ilan between 0.6ml to 1ml ibibigay ko? In between kasi sya, not the exact amount so mejo confusing for me. Thanks sa mga sasagot po.
