Buddhism believes that children can be reincarnated after birth.

Yes, this is the Buddhist way of looking at couples, children, relationships between men and women and friends, not just sons. Buddhism found that the relationship between family, husband and wife, children, relatives and friends, and lovers in this life had great karma in previous lives. Being together generally belongs to the following three relationships:

1. To repay kindness: to be harmonious and beautiful with each other and to love each other is to repay kindness to each other;

2. Come to collect debts: quarrel with each other, and the contradictions are constant, but they don't leave. This is mutual debt collection;

3, debt repayment: the relationship between each other is cold and faint, making do with life, this is debt repayment. So when the debt is paid off and there is no concern for each other, we will separate, and then we will continue the next fate. Therefore, Buddhism does not teach you persistence, but teaches you to live in the present, without fetters, persistence and nostalgia.
