Taking your child’s temperature accurately is an essential step in assessing their health and determining whether they have a fever. The method you choose depends on your child’s age and comfort. For infants and young children, rectal measurements provide the most reliable readings. For older children, oral thermometers are effective if they can hold the device under their tongue properly. Temporal artery thermometers, which measure temperature via the forehead, or tympanic thermometers for the ear, offer quick and non-invasive options for all ages. Always clean the thermometer before and after use, follow the device’s instructions, and ensure your child is calm during the process for the most accurate results.
If your child feels warm or seems unwell, knowing if a fever is the cause can be helpful. Here’s how to take your child’s temperature safely and accurately.
What Type of Thermometer Should I Use?
Digital thermometers provide the quickest and most accurate readings and are the only type recommended by doctors. There are three types available:
- Regular digital thermometers: These have a straight shape with a temperature sensor at the tip and a digital display. They can be used for rectal, oral, or axillary (armpit) temperature measurements.
- Ear digital thermometers: These measure heat waves from the eardrum using a plastic probe placed inside the ear. They are suitable for children aged 6 months and older.
- Temporal artery digital thermometers: These measure heat waves from the temporal artery, a blood vessel across the forehead. They can be used for all ages, including infants and adults. Follow the specific instructions provided by the manufacturer, as they may vary.
Always check the manufacturer’s instructions to understand how the thermometer works and how it signals that the reading is complete.
Note: Some thermometers are not recommended due to inaccuracy, including plastic strip thermometers, pacifier thermometers, and smartphone temperature apps. Also, avoid using glass thermometers, as they are unsafe.
Tips for Taking Temperatures by Age
Taking a child’s temperature can be challenging, especially if they are squirming. The best method depends on the child’s age and their ability to cooperate:
- Babies younger than 3 months: Rectal temperature measurement is the most accurate.
- Babies 3 to 6 months: Rectal temperature is best, but you can also use the temporal artery or axillary methods.
- Kids 6 months to 3 years: Rectal temperature is ideal, but you can also use the temporal artery, ear, or axillary methods.
- Kids 4 years and older: Oral temperature is best if the child can hold the thermometer under their tongue correctly. If not, use rectal, temporal, ear, or axillary methods.
Regardless of the method you use, keep these tips in mind:
- Avoid taking your child’s temperature immediately after a bath or if they have been under blankets, in multiple layers, or swaddled. This can affect the accuracy of the reading.
- Always stay with your child while taking their temperature.
