I guess I am thinking along the same lines as Playfelt...why does this have anything to do with the parents?

As a matter of fact, as a parent I would be upset with my provider if they were so angry and upset about a poopy mess that more than likely could have been avoided or at the very least interupted BEFORE the giant mess with a bit more closer supervision.

Plus you already acknowledged that this child knows how to take the sleep sack off since you mentioned it to DCM numerous times already. Knowing that information would have caused me to keep a much closer eye on the dck during nap times.
