What do you call a vagina in your house?

My husband and I are in a heated parenting discussion about what we will call babys vagina. The term/nickname she will grow up using. 
My husband says jay-jay. I think that's too adult. 
I say hoo-hoo. He says it will confuse her relationship with owls..... 🙄
Help me. What nickname do you use? Thanks in advance Glow world.
