Yes, regardless of adults and children, after his death, his family will read Buddha for him, which will increase his incredible blessings and merits. It is best to read Tibetan scriptures on the basis of vegetarianism. This is not only beneficial to the dead children, but also beneficial to the deceased relatives and the living. The Dizang Sutra is a filial piety sutra that benefits both Ming and Yang. The most frequently used meritorious service book is the Tibetan scriptures. If you really have difficulty reading by yourself, you can go to the temple and ask a prayer flag for a certain fee, so that the monk can read books instead of his family.
It should also be noted that vegetarian chanting is different from fasting chanting. Fasting and chanting Buddha refers to stopping eating after noon until sunrise the next day except drinking water. This is called not eating at noon. Also known as fasting. But fasting is not always vegetarian. A vegetarian who doesn't eat after noon is also called fasting, but a vegetarian who wants to eat dinner all day can only be called vegetarian, not fasting. Therefore, the vast majority of people are still vegetarian and chanting Buddha, but they have not reached the level of fasting and chanting Buddha.
