Kaddish

Excerpt from My Jewish Learning: Traditionally, Jews are required to say the Kaddish for 30 days after burial for a child, spouse or sibling, and for 11 months after burial for a parent. From then on, one recites Kaddish (1) on a loved one’s yahrzeit (the Hebrew anniversary of their death) and (2) at Yizkor (memorial) services. Some people say Kaddish for the departed not only at (1) and (2) but daily at every prayer service. What is your opinion on this practice?

My mother died on March 9, 2o20. When exactly do I finish saying kaddish? Thank you.

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?
