A hygienic oral feed-bottle nipple includes an opening skirt to expand and rotate in the buccal vestibule. As the child completes the suckling cycle, the mouth portion is distorted, the skirt extended to provide cleaning, stimulation, and a bumper to deny extensive pronation. The flanges and skirt may be covered with a textured surface, or bristles, that provide mechanical brushing of oral surfaces. Hard pads set along a superior surface of the nipple are compressed against the maxilla palate and provide upwards and/or lateral force to encourage lateral expansion of the palate. The nipple may be bifurcated into left and right opposing lobes which can split laterally to enhance lateral force on maxilla.
