Abstract
A pacifier includes a nipple, a shield and a handle. The nipple comprises a pair of wings extending longitudinally along a bulbous end of the nipple. The wings allow for air to exit and enter the space between the palate and the nipple to prevent a vacuum therebetween. Alternatively, the nipple has a channel system comprising a series of holes on the surface of the nipple, some contacting the palate, to also allow the air to enter and exit the space between the palate and the nipple. The stem of the nipple may also have a transverse hole which receives the baby teeth to prevent an open bite.
