What age is acceptable to let your daughter start shaving their private parts

Brittany • God is within her, she will not fall; God will help her at break of day. -Psalm 46:5💕
I'm curious to know everyones opinion on this subject. For me personally, I would say 11 or 12. I had hair on my vagina around 11 and I also started my period around that age as well and it made me feel yucky having to have blood on my pubic hair especially with wearing pads.(Sorry if this is TMI).
