Answers: Whatever that response is wrong. My son started going through precocious puberty before 7. It can be serious. It can be a sign of cancer, a brain tumor or freshly early change. If it is the latter it can still cause problems because their bones will fuse before than they should causing them to be immensely short statured. They should not start developing pubic hair until around 10 according to the 4 doctors that hold examined my son. Your not going to cause your kid to ave mommy issues for examining his body at that age so long as i.e. all your doing. I enjoy 5 boys from age 20 to 1. Not one as mommy issues because of my checking things when they are young. Make sure you explain single mom and the dr can look and only the dr should touch.
why are you looking at your sons hole?
Yes every child have the "puberty only" hair from birth , it is simply still blond. 9-12 is the right time for puberty to start. but som eit is younger others older. Quite looking at you sons private areas you'll provide him mommy issues
