Ask ko lang if okay lang ba ang cool fever for a 2 months old baby. He has fever

Nag immunize kami kanina kay baby sa barangay and now he's sick with a temperature of 3i.4C°. First time mom here. Ano ano po ba dapat gawin aside sa pagpapainum ng tempra? respect post and TIA #advicepls #firstbaby #1stimemom #sickbaby #2monthsbaby
