Abstract: A flexible neck baby bottle (10) comprises a nursing container (12) having a neck (14) at an open end, to hold a liquid therein. A nipple assembly (16) is adapted to be received in a mouth (18) of a baby (20). A structure (22) is for mounting in a watertight sealed manner the nipple assembly (16) to the neck (14) of the nursing container (12). A facility (24) in the nursing container (12) directly below the neck (14), is for allowing bending of the neck (14) with the mounting structure (22) and the nipple assembly (16) freely in any direction without inhibiting a flow of the liquid from the nursing container (12) out through the nipple assembly (16) and into the mouth (18) of the baby (20), so that the baby can easily maneuver and orient the nipple assembly (16) at any angle when nursing.
