Abstract: Breast milk collection, storage, and feeding apparatus comprising a first storage bottle and first and second differently sized feeding bottles, each of the three bottles having a mouth portion of the same diameter and a common external thread structure, and first and second dual port caps each sized and threaded to attach to each of the three bottles, each dual port cap further having a drip port and a draw port, a pressure relief vent formed therein; and a tethered closure plug unit attached thereto, each tethered closure plug unit having first and second tethered plugs shaped and dimensioned to plug or close a respective one of the drip and draw ports. The apparatus may be used in various manners to transfer milk from the storage bottle to a feeding bottle and to thereafter feed an infant by nipple, syringe, or a gravity/bolus technique.
