Is 99.9 a fever for a child underarm?

My little daughter has a temperature of 99.9 underarm. Is this considered a fever for a child? Should I be worried and give her some medicine?

Yes, for small kids, underarm temperature is usually one degree lower than oral. So 99.9 underarm means the child might have a real fever around 100.9. Please wipe the baby with room temperature water and keep them comfortable.

I was searching about underarm readings for my nephew recently. Since armpit readings are slightly lower, 99.9 underarm actually points to a mild fever. It is good to keep tracking it every few hours.

I am not a pediatrician, but I have heard from doctor friends that underarm temperature is always slightly lower. So 99.9 underarm could indicate a fever. Keep the child hydrated and monitor them closely.

For kids, we have to be very careful, just like I have to monitor my BP. An underarm reading of 99.9 is definitely a mild fever. Make sure the child's room is airy and call your pediatrician for advice.

Yes, 99.9 underarm is a low fever. You can do a gentle sponge bath with lukewarm water to bring it down naturally. But if the child is lethargic or refuses milk, go to a pediatrician immediately.

My daughter had exactly 99.9 underarm last week. Our pediatrician confirmed it is a mild fever because underarm is usually lower. We just gave her prescribed drops and she was active again in a day.

Kids these days get warm so fast, it is exhausting! Yes, 99.9 underarm is a slight fever since that area is cooler. Keep them in loose cotton clothes and don't let them run around too much today.

That's a mild fever because armpit readings run a bit lower. Give the kid some light khichdi or warm apple puree if they are eating, and don't worry too much. They just need rest.
