Your friend is lucky to have you in her life. And it's shocking how many medical people are clueless. But do remember that early menarche in girls has become more and more commonplace, brought on by hormones in cosmetics (I shudder when I see little girls playing with makeup, for numerous reasons) and also in our food. It may not be the jab. But, yeah, it's true - in all likelihood it is. So tragic. Keep ranting!
