I think everyone do things different. That appeal of dayhome, always someone who offer what parent prefer. To me, not right way or wrong way but important to be transparent.

If family join day care knowing husband work from home, or husband cover day care when provider have appointment, or husband come home at lunch time, then that obviously not concern for family. It when parent see situation they not expecting or aware of, that appear to be issue.

For me, if parent, I want to know who is in contact with my child. And maybe want police check if regular interact but just because my child in day home, I would not presume or expect immediate family to be interacting with child. If someone family is regularly involved with business, I think that needs to be clear from beginning and then no misunderstand or surprises.
