What is OC, now I forgot what you typed. It is lack of oxygen to my brain this time of the night. I assume that, that can happen to many children without CAH. I read somewhere that now they are blaming the amount of steriods put in the milk they drink and the meat they eat. Scary. They said puberty is getting younger and younger. I wonder how they base a starting time for your child. I assumed if the mother started young, so will the daughter. I am hoping my daughter takes after me and starts late. It seems so many factors can play into puberty. Ugh!
