Last night when getting ds1 ready for bed I got a whiff of pungent bo from one armpit. He obviously knew he was smelly because he laughed saying "smell my armpit!"
A friend with a son in the same class as ds1 said that the teacher had recently mentioned that the smell in the classroom was not her but one of the kids, and that she had flagged possible early puberty with the head teacher. Now I am worried that this is ds1 - but there are lots of much more mature girls than him in the class.
Nobody who is close to him has smelt this before and he has no other signs of puberty - although he is quite moody (I don't think this is new!)
I called the gp this morning who called back saying the paediatric endocrinologist wants to see him within a month. Obviously I have now googled and am neurotic that he has a brain tumour
.
I do have health anxiety but I also know that precocious puberty in boys as opposed to girls is a cause for concern. 
I think precocious puberty is a bit of a leap - his penis and testicles are normal, no pubic or facial hair and no acne. Does anyone else please have any comforting stories of ds with similar? Thank you.
