The Pacifier Thermometer is a soother with a built-in early-warning system. It lets you know when your baby is coming down with a fever by changing its color in stages from blue, which indicates a normal temperature, to red, which shows a fever. Infants cant tell you how they feel, so this is an effective method to help parents find out that there is a problem before the problem becomes serious.
A change in colour registers temperature change and communicates it to the parents. The pacifier, as constant fever detector.Designer
