A friend of mine is a single dad raising his daughter, who will be twelve next month. Her mother (my best friend) died three years ago. I feel for him having to figure out a way to teach her about her cycle, if he hasn’t had to already.
Teaching the biology of it is the easy part, compared to trying to deal with the overt sexualization of children from todays culture. When you listen to what passes for popular culture - the music, the movies, everything that’s easily accessible on the internet - - I don’t know how any parent does it...
I wish them all good luck, the kids will need it.
