Americans won't have more children because the cost of a nanny for all those extra children would be prohibitive.
American women sure as heck WON'T stay home, have children and ACTUALLY stay home to take care of them! Too selfish.

The ability of Kate and William to influence western civilisational trends is grossly exagerated. If they have more than two children they will be berated, not copied.

I have several sets of words to describe why more (usually) western, caucasian males aren’t having more children:

1. “Family” Court
2. Divorce Industry
3. Matriarchy, errrrr I mean “Child” support

How about getting back to the subject? The White Western birth rate is way down. If present trends continue, whites will be a minority in the U.S. in thirty years. As for England, if present trends continue, whites will be a minority in 2066. It’s going to make our countries unrecognizable.
There are several reasons for this, a combination of factors, not least of which are out cowardly “conservative” politicians.

Here's my take:

Having your first child is hard because you don't know what to do.

The second child seems perfect especially if you have a boy and a girl.

With the third baby it begins to feel like a real family.

With the fourth it is just one more.

We had four which is nothing because my mom had ten.

A well-trained group of kids make for nice full get togethers later on.
