What is the first stage of most procreational marriages?

Child-rearing is a subsequent stage that occurs after marriage. It involves the processes and responsibilities of raising children, which typically begins once a couple has established their marriage and decided to start a family. Therefore, child-rearing cannot be the first stage of marriage as it is contingent upon the marriage itself.

Courtship is a phase that usually precedes marriage and involves the couple getting to know each other, building a romantic relationship, and determining their compatibility. While important, courtship is not the first stage of marriage but rather a precursor that leads to the commitment of marriage.

Later life refers to the stage that occurs after marriage and child-rearing, typically when the couple is older and may reflect on their life experiences together. This is clearly not the first stage, as it comes at the conclusion of a couple's shared journey through marriage and family life.
