Abstract: Disclosed herein is a disposable infant feeding bottle including a disposable water bottle comprising a neck adapted to attach to an infant feeding nipple. For example, a disposable infant feeding bottle can include a disposable bottle having a neck; water, contained within the bottle, in an amount sufficient to be mixed with infant formula to feed an infant, and in an amount that is less than the volume of the bottle so that infant formula mix can be added to the bottle to mix with the water without overflow of the water or the infant formula mix, such as about 2 to about 16 ounces of water. The infant feeding bottle may further include a coupling component configured to allow an infant feeding nipple to be removably attached to the bottle, wherein the coupling component forms a liquid-tight seal when the nipple is attached to the bottle; a disposable cap; and a tamper resistant component.
