Where's Harper?

Harper asks me, no less than a gazillion times each day:
"Where's Lucy?" I respond, "at school."
"Where's Dada?" I respond, "at work."
This continues for another hour, until I wise up and ask her where they are. She knows, of course. Then I'll ask, "Where's Graham?" She will point or she will tell me that he is sleeping or playing, or whatever. Then I ask, "Where's Harper?" Her reply is always, "I dunno!" Confusingly enough, sometimes she goes looking for Harper. As long as it keeps her occupied and forgetting to ask me where Lucy or Ian are I won't correct her. I do hope she finds herself though.
