The American Red Cross Infrared Forehead Thermometer lets you take baby's temperature in a gentle way that won't disturb them. This no-touch method of temperature taking lets you take a sleepy baby's temperature while they stay comfortable in the crib. The infrared technology provides an instant reading which is displayed on the large, easy-view screen. If a fever is detected, the silent red-light alert won't startle a drowsy child. There's even a mode for checking bath water and formula temperatures so that you can be sure they're at the right temperature.
