Abstract: A variable flow infant feeding assembly is designed so that a caregiver can select an optimal feeding flow rate without having to change nipples, as may be desired depending upon the age and appetite of the infant as well as the liquid that is being dispensed. Preferably, the assembly includes a baby bottle and a nipple member that has ventilation structure defined therein for permitting replacement air to enter the baby bottle during feeding. Retention structure such as a threaded ring member is provided for securing the nipple member to the baby bottle. Advantageously, variable restrictor structure is provided, preferably so as to be integral with the ring member, for selectively blocking at least a portion of the ventilation structure. By controlling the size of the opening through which replacement air flows into the baby bottle, the variable restrictor structure permits the feeding flow rate through the nipple member to be adjusted by a caregiver.
