Abstract
The present invention pertains to a pacifier shaped teether with an internal bladder filled with food grade propalyne glycol which can be brought to freezing temperatures while maintaining it's liquid nature. There is a hollow portion in the mouth guard of the pacifier which is connected to a hemispherical chamber allowing room for expansion of the bladder into the chamber as the nipple is being sucked. One or more pacifier shaped teether(s) may be stored in a portable, insulated, gel ice filled storage container thereby keeping the pacifiers cold for several hours.
