“With regard to physical, economic, psychological and social conditions, responsible parenthood is exercised by those who prudently and generously decide to have more children, and by those who, for serious reasons and with due respect to moral precepts, decide not to have additional children for either a certain or an indefinite period of time.”
Humanae Vitae Pope Paul VI
Compendium of Social Doctrine (other compendium…)
“232. The family contributes to the social good in an eminent fashion through responsible motherhood and fatherhood, the spouses’ special participation in God’s work of creation[519]. The weight of this responsibility must not be used as a justification for being selfishly closed but must guide the decisions of the spouses in a generous acceptance of life. “In relation to physical, economic, psychological and social conditions, responsible parenthood is exercised both in the duly pondered and generous decision to have a large family, and in the decision, made for serious reasons and in respect of the moral law, to avoid for a time or even indeterminately a new birth”[520]. The motivations that should guide the couple in exercising responsible motherhood and fatherhood originate in the full recognition of their duties towards God, towards themselves, towards the family and towards society in a proper hierarchy of values.”
“234. The judgment concerning the interval of time between births, and that regarding the number of children, belongs to the spouses alone. This is one of their inalienable rights, to be exercised before God with due consideration of their obligations towards themselves, their children already born, the family and society[528]. The intervention of public authorities within the limits of their competence to provide information and enact suitable measures in the area of demographics must be made in a way that fully respects the persons and the freedom of the couple. Such intervention may never become a substitute for their decisions[529]. All the more must various organizations active in this area refrain from doing the same.” (

The serious reason does
not = only life or death reasons.
There can be all sorts of things that come up in life…that fit such.
The couple must make the judgment before God (perhaps seek advice)
