Well, I know several software engineers with kids in NYC. Some live in NJ, some live in Brooklyn, some live in Manhattan. In fact, among married immigrants almost everyone has at least one kid after 30. Often mother does not work or works part time and looks for kids. Almost everyone of the "extreme commuters" has kids.
Tuition and health insurance is about the same everywhere. Housework is not that hard, maids are not that expensive. Absolute cleanliness is not something that kids require, neither is owning a (2-bed, 3-bed, huge) house.
In my opinion, your restrictions are quite arbitrary. So you would not have kids while working as a software engineer, but plenty of people do.
