What is considered a fever for a newborn?

For a newborn, 100.4 F (38 C) is a fever, and it is a matter that needs prompt medical attention. Since they are only on mother's milk or formula, make sure they feed frequently to avoid dehydration. Please don't try any home remedies on such a small baby; take them to a doctor.

I read that 100.4 F is a fever for a newborn, and it makes me so incredibly nervous. My baby is just 2 weeks old and I keep checking her forehead every hour. Did anyone else feel this constant anxiety about their newborn getting sick?

My older sister just had a baby and the doctor told us that even 100.4 F is a proper fever for a newborn. It's actually a pretty big deal for babies that tiny. We were told not to give any medicine on our own and just call the pediatrician right away.

According to standard pediatric guidelines, 100.4 F (38 C) measured rectally is the fever baseline for a newborn. I keep a digital log of my baby's stats on my parenting app. For babies under 3 months, always call the doctor immediately if the app or thermometer shows 100.4 F or higher.

Yes, 100.4 F or higher is the fever limit for newborns. When my daughter was just 3 weeks old and touched 100.5, we rushed to the emergency room as advised by our doctor. Don't wait to see if it goes down on its own with small babies; get professional medical advice immediately.
