No I don't have kids, which is why I'm able to imagine making that choice. I agree different people will have different choices, just that the parent might need to ask a different demographic.

Even with kids, parents that aren't well off often sacrifice their wellbeing for their family. For example, people that work two jobs for a total of 16-18 hours a day aren't rare where I live. They are aware this affects their health, shortens their life span and their time with kids, but they make the choice so that their family could survive.
