Abstract: A baby pacifier that provide supplemental oxygen to premature babies and other infants requiring such includes a housing that housing includes a front surface adapted to be symmetrically disposed about the baby's head at the mouth and nose areas, and a resilient nipple. The housing has an interior chamber into which supplemental oxygen is directed through an oxygen inlet opening of a barbed elbow or stem into the interior chamber. The oxygen inlet opening is adapted to be coupled to the external oxygen source using an external oxygen supply conduit. A plurality of oxygen delivery holes extend from the interior chamber through the housing about the baby's mouth and nose areas to allow supplemental oxygen to flow outwardly from the interior chamber. The nipple pacifies the baby during suckling while centering the baby pacifier about the baby's head at the mouth and nose areas.
