Temper fits or temper tantrums? Young children often express their anger by having temper ____. When I were searching for the results, I saw that: "Temper tantrums and temper fits are both correct. In terms of usage, temper tantrums are in fact used much more frequently than temper fits especially when referring to children’s angry behavior." However, many books have the same key - temper FITS. I'm not really sure which one is the best choice.
