That is one of the reasons I won't interview a mother without the child. I did have one mom come a few years ago who had set up appointments to gether info from several daycares as a way of ruling out the ones she didn't want and then once she had narrowed it down to 5 she was going to bring hubby and child for a second interview. I just didn't like her attitude at the interview so didn't allow her to come for the return interview.

I have had a potential daycare provider ask to come over during the day to sort of observe and decide if she was as committed to it as she thought. I let her come because I knew her but not sure I would let a stranger do that. Would totally depend on how they got my name.
