Abstract: A nursing bottle with a nursing time indicating device, which includes a bottle body, a bottle cap screwed to a mouth of the bottle body, a protective cap rotatably covered over the bottle cap, and a nursing time indicating device including an indicating sign and a scale structure separately but correspondingly provided on the outer surfaces of two different components of the nursing bottle that could be turned relative to each other. When the two components bearing the nursing time indicating device are rotated relative to each other to align the indicating sign with a desired position of the scale structure, a specific time may be indicated. A reminder, such as a phrase, is provided next to the indicating sign to clearly define the meaning of the specific time indicated by the indicating sign and the scale structure. Therefore, a nurse may conveniently notice the correct time for nursing an infant.
