An infant feeder has a handle with a proximally extending tongue and a pouch assembly for fitting over the tongue. The tongue has first and second axially spaced apart detenting structures. In a first configuration, a pouch assembly detenting structure is engaged with the first tongue detenting structure. In order to achieve a second configuration, a predetermined axial force is applied to the pouch assembly relative to the handle, so as to disengage the pouch assembly detenting structure from the first tongue detenting structure, slide the pouch assembly distally down a sidewall of the tongue and engage the second tongue detenting structure. This decreases the size of the food volume bounded by the pouch assembly and the tongue, and proximally displaces any food contained therein.

A feeding device includes a fluid reservoir and a nipple configured to be attached to the fluid reservoir. The nipple includes a base portion and a teat portion, where the base portion and the teat portion together define an interior space of the nipple. The nipple also includes a removable flow valve configured to be positioned within the interior space of the nipple and an internal cavity between the removable flow valve and a wall of the nipple. The removable flow valve includes a central opening and at least one valve protrusion extending from a surface of the flow valve into the internal cavity. The removable flow valve is configured to adjust a flow rate of a fluid from the fluid reservoir into the internal cavity.

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.
