Slightly different perspective on this. What if you arrive, have a young family and cannot get your child into school (RP issues etc). But are keen for the child to have some social interaction with other kids.

Some families have no alternative but to use an unlicensed nursery. The one our friends use the mother isn't allowed to leave the child she goes to another room in the house, so this is slightly different I admit.

Don't always think people are just abandoning their kids. As with the people we know they are just keen their daughter doesn't become a social hermit and cannot interact if / when their family RP comes through and she can go to a proper pre - school
