If they are normally in care 3 days/week that's what I would ask them to pay. If they have used more 4 day weeks than 3 day weeks I would ask them to pay for 4 days.
Always ensure that your child receives quality care by taking the time to investigate the provider and by asking for references! We simply cannot verify the claims of every daycare provider.
Updates
We expect providers to keep their listing and available openings up-to-date. However, to prevent oversights, openings expire after 45 days.
