A parent can snuggle multiple kids at once, read to multiple kids at once, take multiple kids to the zoo at once, etc.
Moreover siblings have their own rich relationships.
Having closely spaced siblings is pretty normal.
And in the year of our lord 2025 it's normal not to have kids in the west.
In most of the rest of the world neither of those things were normal.
Which is the point.
The west is weird when it comes to raising children and has been uniquely bad at it for over 80 years which happens to be living memory for pretty much everyone on here.
You can see the change in the Boy Scout manual.
That the majority of conservatives today pine for the 50s us that we not only lost the ability to have a stable society but even the memory of what one should look like.
