I work in the restaurant industry and I can assure you it is not impossible because millions of Americans are doing it. Most of the time the child ends up with the grandparents while the parents work. That is if the grandparents are not working...
The grandparents are caring for 4 kids under 6 daily in millions of American families?
Also, most grandparents in fact are in working age when the grandkids are small. Some are sick, some never returned to work after kids grew, but quote a few always worked or returned to work. And even with those who are at home, asking them for daily babysitting of 4 kids is quite a lot.
