Abstract: Embodiments of a bottle holder are shown and described, each embodiment having an enclosure wall, with an open mouth and an open bottom, into which a disposable liner may be placed. The bottle holder has a lip around the open mouth, over which the open end of the liner is placed and onto which a nipple assembly is secured. The bottle holder also has a bottom support flap that may be pivoted across the open bottom and secured by a latch-means. This bottom support flap forms a temporary floor, which is especially useful for supporting large liquid volume, such as a two-quart calf feeding. Optionally, the bottle holder may be tapered and made stackable.
