As to the gluttony thing- you do realize childbirth changes a woman’s physiology? Age? Medication side effects? Good grief, then there is the fact that our Good Lord made different body types in general... ???
But that didn't stop our Grandmothers and Great-Grandmothers, who had more children, from staying fit. In fact the whole notion of having a large family presupposes that the wife stays fit. (Don't get me wrong the husband should as well, g
luttony is a mortal sin.) Telling a naturally ordered man to be okay with extreme overweightness and obesity in a wife is akin telling him to be okay with sodomy; it ties back to disgust sensitivity. In fact
, it's no surprise that fat acceptance and sodomy acceptance arise at the same time.
