Question
When a parent passes away, the child says Kaddish for eleven months, not twelve. I know it has something to do with the soul of the departed. Question 1: Does a parent say Kaddish for eleven months for a departed child? It is the custom of some people to say Kaddish for eleven months even if it is not mandated - for example: husband for departed wife, sibling for departed sibling. Question 2: Should someone say Kaddish every time the Mourner's Kaddish can be recited after the twelve months? How does that reflect on the departed person's soul?
