Serious question - What name can I use for lady bits for a little girl to use?

I call them "bits" at the moment. As in, wash your bits when she's in the bath. I can't use Minnie as my daugher loves Minnie Mouse. Can't use Lou Lou as she uses that for Yoghurt (Petit Filous lou). Can't use Nu Nu as that's the Hoover in Teletubbies. Much easier for boys' bits.
