Abstract: A non-toxic luminescent nipple retaining collar is provided for baby bottles which enables those bottles to be seen and retrieved in the dark without the aid of light. The invention aids parents in locating the nursing bottle without turning on the light and completely awakening a child or others in the room. The child, if old enough, can retrieve the bottle himself and save the parents a trip. The retaining collar can absorb and store light from any natural or incandescent light source and emit that light for an extended period of time.
