Be sure that the preschool or child care program you are looking into is operating according to the minimum requirements set by your local government. Some programs require licensing, while others may not. I know of a few amazing programs across the U.S. that are not licensed, but are still legal and would be wonderful options for families. It's important that parents do research, get referrals, look up ratings (if available), and truly find out what goes on inside of any program they have decided upon.
In monetary- and production-based societies, informal childcare is seen in families who do not have enough funds to finance placing their children in a more expensive child care facility. A study done by Roberta Iversen and Annie Armstrong explains that due to long and irregular working hours of working parents, low- socioeconomic families are more likely to utilize informal childcare. Those low income families are also more apt to work longer hours on an irregular and inflexible schedule, which ultimately makes using a childcare facility, that has regular business hours, unlikely.
