Not just materialistic, but individualistically proud. We shouldn’t turn this into a kind of reverse moralism where we robotically shame those with few or no children, or even go celibate (we can’t always know why). But humans were put here for God’s loving glory and if the love capacity is there for many children, it is only right by God to follow suit.

That is an example of a good argument for fecundity. There are others, including propagating values, maintaining national identity and strength (witness Japan which may soon collapse), and others not so much rooted in “if it wasn’t for...”
I don’t think that anyone would shame a couple for not being able, for whatever reason, to have a big family. If anything, the feelings are empathy, with some pity and shared sadness.
On the other hand, there should definitely not be any shaming for couples that do have a bunch of children. Right now there is a lot of passive and active hatred of people like the Duggars, with 19 children.
