I wouldn't allow him back into daycare without pull-ups/diapers (same thing in my opinion). Not a chance would I be cleaning that up 3+ times a day. I have one here who will be 4 in Aug and still must wear pull ups because she will just smirk at me and pee right in front of me! It is certainly NOT an accident at that age, and in my opinion should be disciplined!
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.
