As Torben mentioned, you do not want to bundle them up and risk raising the fever.
However, the opposite extreme is not helpful, either. Undressing the child, cold baths, ice, or alcohol rubs can lower the skin temperature without lowering the fever. This can cause hivering, which can actually raise the core temperature further.
- Do NOT bundle up someone who has the chills.
- Remove excess clothing or blankets. The room should be comfortable,
not too hot or cool. Try one layer of lightweight clothing, and one
lightweight blanket for sleep. If the room is hot or stuffy, a fan
- A lukewarm bath or sponge bath may help cool someone with a fever.
This is especially effective after medication is given -- otherwise
the temperature might bounce right back up.
You are spot-on with suggesting plenty of liquids. Water, gelatin, soup, or even popsicles are all good ways to keep your child hydrated.
The old adage "feed a cold, starve a fever" is bad advice. If your child is hungry, let them eat.
As always, call your doctor if the fever gets too high:
- Is younger than 3 months old and has a rectal temperature of 100.4 °F (38 °C) or higher
- Is 3 -12 months old and has a fever of 102.2 °F (39 °C) or higher
Also call your doctor if the fever doesn't show signs of going away:
- Is under age 2 and has a fever that lasts longer than 24 - 48 hours
- Is older and has a fever for longer than 48 - 72 hours
