I know this is an AWFUL thing to ask, but think this.

If your daughter went to an adult and said "that man touched my..." what would she say? And what would that adult say?

Vajayjay or Mrs Wuz Wuz... "oh, did you not want him to play with your Dolly?"
Bits... "OK then love" thinks "bits of what?"
Weewee "that's not nice, is it?" thinking "sick freak playing with urine"
Flower "Oh did he?" thinks "and you're saying this because?"
Bum "oh dear, not nice!" and again thinking "I wonder what that was about?"
eta - HooHaa - thinks "aaah, one of those insidious night garden toys"

As I say, not a nice thought but you have to protect children these days. BTW, is there a better term than Vagina to cover the whole area? Be great to learn it!
