A method may be provided for controlling a laundry treating apparatus. A first speed rotating may control the drum to accelerate the drum to rotate at a first speed, a braking may apply a brake to stop the drum, a second speed accelerating may accelerate the drum to a second speed, a current sensing may sense a current being applied to the motor during the drum is accelerated to the second speed, and a laundry amount determining may determine a laundry amount based on the current sensed in the current sensing.
