The Anxious Hand on the Forehead When a baby feels warm, a parent's first instinct has always been the same: placing the back of their hand against the child's forehead. For thousands of years, this subjective "touch test" was the only way to gauge a fever.

The first sealed glass thermometer containing mercury was invented in 1714 by Daniel Gabriel Fahrenheit. However, using a delicate glass tube filled with highly toxic liquid on a squirming infant was a terrifying task. Even into the late 20th century, taking a baby's temperature required a rigid glass thermometer and several highly stressful minutes of holding a sick baby perfectly still.

The Digital Revolution The leap to safety and convenience happened in the 1990s with the widespread adoption of digital thermometers, followed shortly by tympanic (ear) thermometers that used infrared technology to read the eardrum's temperature in mere seconds.
