Mourning and minors

Hi,

One should not obligate minors to fulfill the practices of mourning, even if they are over the age of education. There is more reason to obligate a minor [older than the age of education] in tearing keriah, but even this is subject to debate, so that there is justification for refraining.

(Rav Moshe Feinstein, Igrot Moshe Yoreh Deah 1:224)

Have a good day,
Mordechai
