Ok, I see your point. If the farmer were to grow a crop that didn't require such rapid harvesting, the workers would end up doing the same labor over a longer period of time which could allow them to have lower child care costs. On the other hand, it would then take them longer in terms of calendar days to get the same income, and all their other expenses are likely to stay the same. If they normally moved on to other jobs after the harvest, this would mean reduced overall income. Also, the difficulty of the job is factored into the pay they receive (the article specifically says their hourly wage is higher than normal farm labor), so they would likely be paid less for this less demanding crop. It still doesn't seem like much of a solution.
