I'm not the best apologist for CSPP. The whole contraception thing is easy to pose in theoretical terms: although there may be allowances for extreme cases of unique hardship, contraception is out. But how extreme, and how unique, and what hardship? How hyper does the emesis have to be to make some NFP-accomplished spacing morally defensible? How poor is poor enough in our climate-controlled, overfed society? Does mom's psychological stability count for anything when it can't even be quantified? How do we measure up to our foremothers who didn't have any options when it came to family sizing regardless of how they felt*?
Even more concretely, I know only a few people who haven't encountered at least one more or less extraordinary hardship along the way. May the bold and winning personalities over at All Onan, All the Time (kidding! kidding!) have mercy on my soul, but I don't want to be the one telling the real women who throw up for months, have difficult and protracted deliveries, will never be the same after 4th-degree lacerations, fight true demons postpartum, suffer repeated miscarriages, etc., to grin and literally bear it. Babies ad menopausum is a darn tall order for someone like me who has never had a serious or lasting complication. What about these girls who don't have it so comparatively easy?
To calm myself down when I start getting unhappy about all this, I remind myself of something that I'm pretty sure I came across, surprisingly, in one of those rabid papist books on the topic. For those who doubt or question, who fear or resent, with scary pasts or unpromising futures, don't try to force yourself to decide to have 53 babies. Just decide to have one (or one more). Maybe it won't be as bad as you think. You won't know until you try.
Or maybe it will be as bad as you think. But you'll have received another immeasurably precious gift of God.
I don't know what's going to happen anyway. My next baby may be my last. My last baby may be my last. For a long-ranger worrier like me, this is a hard lesson. But I know that what I need to do is just trust God today, and then do that every day (including the day I get pregnant, the day I don't get pregnant, the day the baby is born, the day the baby still isn't born). And also not think about how much I don't want to go through labor again.
*I know, all historical periods have had their methods of limiting children without abstinence. But not all people have.
