Earlyish puberty

[namechangedforthis1980]

Hi

DS ( aged 10) has a tumour which affects his optic nerves and his hypothalamus. We've just been to see the endocrinologist- we've been seeing her since DS turned 9- and she's confirmed he's definitely in puberty.

We're wondering how this will affect his height as he's earlier than average. He's a tall boy, always has been and is now 5ft 2. Genetically he was always likely to be a tall adult - I'm 5 7, his Dad is 6ft and his 15 year old brother is 6 2 and still growing .

The endocrinologist thinks there will be an impact on his height and he's likely to now be more average height. We're happy with that ( not much we can do!) but I'm worried about him being smaller than that. He has enough other stuff without being short

I know that sounds terrible, but I spend my life wanting to wrap him up in cotton wool.

Has anyone had a son who's gone through puberty earlier than average? How has that impacted his height? We knew he had early signs last year but because he was 9 they wouldn't do anything to halt it

Thanks

Are the signs of very early puberty (e.g., just very light fluff where it wasn't before?)? Because the lag from that to full puberty can be substantial, can't it? (though I guess an endocrinologist will be going on detailed info)

Also, yes I do have an example - not my own child, but my godson started puberty at 9.5, was fully pubescent by 11, and is now (at 15) 6 foot (taller than either of his parents).
