I stay nice and professional (they might have a normal friend to send my way one day, or the infant could one day attend my preschool program), but I do shorten the tour, and I don't ask further questions of them (just answer their questions). Then I tell them at the end it was nice to meet them and I'll be in touch. I message shortly after, either saying I feel a centre would be a better fit, or that I can't accommodate xyz that they need. If it was an interview for waitlist, I just say I'll contact them if a space opens for them (it never will, but I hate to burn bridges just in case... small town).
Never thought of keeping positive lines open Incase friend or neighbour may need care.... good point
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.
