What is a fever for a 3 month old?

My 3-month-old baby seems to have a slight fever, and I'm trying to figure out if it's serious enough to call the doctor. Can anyone tell me what temperature counts as a fever for a 3-month-old?

Please don't listen to online suggestions about giving herbal syrups to a 3-month-old. A rectal or underarm reading of 100.4 F or higher is a fever. Always verify with your child's pediatrician before doing anything.

Just like we track our heart rate, tracking temperature accurately is key. For a 3-month-old, 100.4 F or more is a fever. Keep the baby hydrated with breastmilk or formula, and get them to a doctor.

Dear, a temperature of 100.4 F (38 C) or above is a fever for a 3-month-old baby. Make sure to dress them in a single layer of light cotton and contact your pediatrician for guidance.

Hey there. For a 3-month-old baby, a temperature of 100.4 F or above is considered a fever. Don't worry, but do call your pediatrician right away because infants this young need to be evaluated professionally.

According to our pediatrician, a fever in a 3-month-old is defined as a temperature of 100.4 F (38 C) or higher. She emphasized that at this age, any fever warrants an immediate phone call or visit to the clinic to rule out infections.
