What is considered a fever in a 3 month old?

My 3-month-old son feels a bit hot to the touch. What temperature indicates a fever for an infant that young? I'm trying to monitor him closely.

A temperature of 100.4 F (38 C) or above is considered a fever for a 3-month-old baby! Since they are still so tiny, it's always best to call your pediatrician for guidance. Sending lots of warmth and healthy vibes to your little one!

Actually, 100.4 F is the fever line for a 3-month-old, yaar. Don't mess around with home remedies or guess the temperature by touching. Just use a proper digital thermometer and call your pediatrician immediately to be safe.

My cousin is 3 months old, and my aunt was saying that anything above 100.4 F is a fever. It's pretty serious for babies that small, so she immediately calls the doctor. Better to get professional advice instead of searching online.

For a 3-month-old, 100.4 F is the fever standard. While you are keeping the baby rested, make sure to take care of your own health too—even a quick 10-minute walk in the fresh air can help clear your mind. Always check with your pediatrician before giving the baby any medicine.

I am not an expert, but pediatricians generally say 100.4 F or higher is a fever for a 3-month-old. Because infants are so sensitive, please consult your doctor immediately instead of taking any chances. I hope your baby feels better soon.
