Why do people plan even their children after marriage? I can understand marriage. But kid too?

Planning a marriage is cool. But why the kids too?

I am talking about mutual decision. Both husband and wife.

Those people should not answer who have taken decisions by themselves without listening to their spouse or just considering their answers instead of actually listening to them.

I was watching a regional movie just now. In that, the husband decides to skip kids by 5 years. But in just 2.5 years from the start, the wife has two abortions. Rendering her incapable of pregnancy due to weak system.

Here, the husband was not listening to his wife's wishes. And she was not making firm statements too. Resulting in surrogacy. And the guy was really practical. A written contract in each and everything. That kind of man.

Hence the question and the description.
