DS had a couple of wispy armpit hairs a few weeks ago, I noticed them while doing a smell-check! We were chatting today and he mentioned he has some on his crotch - and he does! Loads!
DH thinks this is massively too early and we should take him to the doctor, the internet says it is early-ish and that his testicles should grow before he gets pubic hair (I don't think they look any different). But I don't want to take him to the doctor and scar him for life or anything - my mother took me along for my stretch marks and that was horrible and shaming. So we are being very 'cool whatever' about it at home.
He has occasionally-greasy skin, stinky sweat, absolutely NO 'emotional' signs of puberty (many of his peers are very interested in boobs, fancying etc).
I don't really know any other children his age - I don't really feel close enough to his classmate's mums to ask(!!!) and most of my friends have daughters...
