My ds is 8 and is in the 3rd centile for height as far as I can tell on the UK boys centile charts. His dad and I are not tall (approx 5'8" and 5'1") but he is much smaller than the rest of his class and he is starting to notice and getting upset. I am thinking of asking his GP if he can check to make sure he is producing the correct amount of HGH and the possibility of getting HGH injections for idiopathic short stature. Is this the right way to go or do I need to talk to his paediatrician (he has numerous allergies and ashtma)? He has grown approx 3cm in 6 months. I know he might just end up a short adult but I really want to try and maximise his height as my brother was a short adult and suffered a lot because of it.
