A nursing bottle with a vent located in its base. The vent is positioned so that the user can easily open it by pressing on it with a finger or thumb. The vent remains open only so long as it is pressed. Once released, a spring returns the vent to its closed position. The user may therefore set the bottle down without having to do anything to close the vent. The vent assembly may be easily removed from the bottle for thorough cleaning. An access notch is provided so that the user does not have to strain to reach the vent. Mounting features are included to position the notch in a right-handed or left-handed configuration.
