I dont remember ever not having pubic hair.
it was always there but it was very thin.
it started coming in thick when i was like 6-7.
im a really hairy person though.
it grows fast, long, and EVERYWHERE.
but yeah pubic hair wasnt a sign of puberty for me.
i didnt start my period till i was a freshman in highschool.
as for breasts....still waiting for those haha
but yeah your daughter probably is going through puberty.
what with our hormone pumped foods and all.
