What do you call a girls private parts?

I hope this isn’t taken in bad taste!

I have just had a baby girl, and as a mum of two boys (8 and 4) I’m not sure how to tackle this subject!

Basically I need some ideas for the word equivalent to ‘willy’ for girls if that makes sense 🙈🙈

My mum never really had a word for it with me so any of the words you use would be appreciated ☺️
