The conjugal morality of the Church is basically open to welcoming life, but that does not mean that she is a dyed-in-the-wool promoter of births at any cost. In her constant teaching, the Church recommends responsible parenthood. The Church doesn't ask that Christians have as many children as possible, but she does ask that Christians have as many children as they are reasonably and generously able to welcome and raise in the circumstances in which life has placed them.
