Coochy-coo

[Douglas G. Wilson]

Anybody know the etymology of "coochy" as in the "coochy-coochy-coo"
traditionally said to the baby while chucking its chin or whatever?

(My question does NOT refer to a hootchie-cootchie dancer, or to any sex
organ!)

Is this just a nonsense sound? Maybe baby-talk for "cutie" or something?
Maybe from French or Gaelic or something?

Anybody know what book to consult for this question?
