How do you stop a child from hovering around you all day pestering?

I own and run a daycare with 25 kids but I have this one child (6 yrs.) who won't stop hovering and pestering me all day everyday. asking questions like what time is it? when is my parents coming to get me? What are you doing? all day long. Does anybody have any suggestions on how to stop this? I've tried talking to her about it but it doesn't seem to help. Time out for it seems to harsh. any ideas?
