I have an open door policy too. Parents can come whenever they want except during nap time (1 - 3) If they do come though, they have to take the child home with them. There is no "visiting" of your child while in my daycare.
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.
