What is considered a fever in infants?

My little infant is feeling warm, and I'm very worried. What temperature is considered a fever for infants? I want to make sure I take the right action.

Generally, 100.4 F (38 C) is considered a fever in infants. Honestly, between checking the thermometer every half hour and comforting a crying baby, I haven't slept a wink. Just keep them comfortable and call your doctor if the fever spikes.

I think 100.4 F is considered a fever for infants. I am still learning how to manage these things as a new parent. Is it normal for their temperature to go up slightly in the evenings even if they aren't very sick?

100.4 F is the official alarm bell for an infant's fever! Don't let your inner Google-search-monster terrify you, but do call your pediatrician. They are very used to new parents calling at odd hours, trust me!

For infants, a rectal reading of 100.4 F (38 C) or above is medically considered a fever. Armpit readings can sometimes be slightly lower, so use a digital thermometer carefully. If your baby is under 3 months and runs a fever, please contact a doctor immediately.

I completely understand how scary it is when your baby runs a temperature; it can make any parent panic. Medically, 100.4 F (38 C) is considered a fever. Try to stay calm, keep your child comfortable, and reach out to your pediatrician for guidance.
