Coincidentally, today's Dear Abby was about a 7-year-old girl who generates mountains of laundry:

Abby's suggestion was the same: make her help.
Raising the death rate won't help reduce the population. It sounds counterintuitive, but lowering the death rate actually helps lower the birth rate.
Back in the '60s and '70s, a lot of people worried about the "population bomb." A Malthusian nightmare was predicted, as the population grew exponentially, while resources could not.
Well, the population bomb was diffused. The earth's population is still increasing, but at nowhere near the rates it was 40 years ago. Just about everywhere but the U.S., population growth rates are slowing. (And in the U.S., population growth is mostly due to high immigration rates.)
What happened? It wasn't just birth control. Foreign aid groups found that birth control alone did not reduce family size. Instead, better health care, nutrition, sanitation, and political stability led to lower birth rates. Why? Because, it turns out, most women don't want to have 10 children. They do that when there's a high infant mortality rate. If you're not sure any of your children will live, you have more of them, as insurance. OTOH, if you're confident your kids will live to adulthood, having 2 or 3 is enough.
Other factors that diffused the population bomb: women's rights and urbanization. Men often want as many children as possible. It's the women who don't. So women who feel they have the right tell their husbands, "No, sorry, the oven's closed" are more likely to have small families. Urbanization has also led to smaller families, because children who are useful farm hands in the country are only extra mouths to feed in a crowded city apartment.
The ironic thing is, when TSHTF, these factors may well be reversed. And population will start to grow, at the time it most needs to shrink.
