Will the real Che Che please stand up?

Some children create and give names to imaginary friends. Our 22-month old has given herself a nickname.

Che Che apparently lives about 20 minutes in the future of Rachel, doing things Rachel wants to be doing, for instance "Che Che is eating Cheerios." equals "Rachel would like some Cheerios." or "Che Che home." means "Rachel wants to go home." (But then, thanks to family members, "Home, James!" also means Rachel wants to go home.)
