An infant pacifier has a temperature sensitive material mounted on the front forming a “mood stone”. The front of the pacifier would change color based on the body temperature of the infant using the pacifier. The pacifier includes a metal strip or other temperature conductive material that connects to the metal frame of the mood stone and wraps around to come in contact with the baby's lips when the baby is sucking on the pacifier. The metal strip carries the heat from the baby to the stone, facilitating color change as the child's temperature changes.
