Frequently Asked Questions (FAQs)

1. Can we use mercury thermometer for babies?

Never use a mercury thermometer. For infants and toddlers, be sure to use a rectal thermometer correctly. A rectal thermometer may accidentally poke a hole in (perforate) the rectum. It may also pass on germs from the stool.

2. Are mercury thermometers banned?

As a result, a number of states have banned or limited the sale of mercury thermometers, including California, Oregon, Rhode Island, Maine, Maryland, Indiana, Minnesota, and New Hampshire. Some local units of government across the country have issued bans as well, including Ann Arbor.

3. What type of thermometer is most accurate for babies?

Rectal thermometers are the most accurate for infants, according to the AAP. Many parents find underarm thermometers or ear and forehead thermometers easier to use on their children, but for most accurate results, you should ideally follow up with a rectal reading, especially when taking a young baby's temperature.
