How do people do this?

How can fewer than three people take care of one kid. Let alone more? I know a girl with three kids. And a single husband. And two jobs. Let alone the single mothers. My sister is one of them. She raised two wonderful kids. And she works 24/7. I just do not understand how that can be done.

We are working round the clock over here. My wife, her mother, and myself. Granted, things have been somewhat abnormal, with my wife recovering from our harrowing experience. But still.

Three persons per kids. Fulltime. That's got to be the minimum. Right?
