Both of my parents gave me, my younger sister and my elder brother an individual “biology/puberty” lesson. I think i was around nine or ten.
I think my first period arrived when i was eleven or twelve. I was at home. Even though i was a little scared, i was fully prepared and knew what to do.
It’s all too common that mums and dads (not just asian) don’t talk about this kind of stuff with their children. I remember one girl at my school started her period during lunch break and because she didn’t know what a period was, she thought she was dying!!! I hadn’t even started my period then, but i was well prepared and had a little “kit” in my bag, so gave her a sanitary towel and some clean underwear.
I would deem myself a failure as a parent if i failed in preparing my children for some of the realities and certainties in this life.
