How to Buy a Thermometer

Traditional glass thermometers contain mercury, which can be dangerous if the thermometer breaks, so it's wise to obtain a safer alternative.

Difficulty: Easy

Instructions

1. Find out how accurate the thermometer is by reading manufacturer's instructions. Rectal thermometers are usually more accurate than oral thermometers.

2. See how quick the reading is given. Digital thermometers can give a reading in seconds and are easy to read.

3. Use a rectal thermometer for taking a baby's temperature because even a tenth of a degree can make a difference between staying home or going to the hospital. A baby temperature of 100.4 degrees or higher is considered a medical emergency. Consult the manufacturer's instructions to be sure the thermometer can be used rectally.

4. Select a pacifier thermometer as a less invasive choice for older babies who like to suck on a pacifier. Add 0.5 degrees F to the reading to obtain the equivalent of a rectal thermometer reading.

Tips & Warnings

• Ear thermometers are less accurate and more expensive than oral thermometers, but may be used as an alternative when breathing difficulties make it difficult to take an oral temperature.
• Don't buy glass thermometers for children under 3 years old because if they bite down, the thermometer might break and mercury can be toxic.
• Don't buy plastic strip thermometers because they're difficult to read and less accurate; they can also annoy a baby when removed.
