I come from a family of very tall people. 6’7 man and 5’10 female. My dh has a mix of very tall or very short - no in between. My ds’s, both as children, appeared to be following the body types of my family however they never had that “big growth spurt “ that I read so often in secondary. My ds1, 17 is only 5 foot 8 Growing beard hair and my ds2 is 15 and only 5’7 he has a moustache and about three beard hairs. How can this be? They’ve always been given a fantastic balanced diet. Their dad is 6ft and I am 5,6. How can they be shorter than their father? . It’s really frustrating me. I wonder if it is due to the factory polluting the air down the road. There is often a funny smell. I have noticed other chikdren in the area are also short. My family and dh family don’t live near by. At family gatherings the difference is stark. Ds1 was on 99 centile as a child and ds2 75 and they are both now on 50th. I don’t know why I can’t accept this - it feels it’s my fault for their stunted growth and it upsets me a lot . I need to know why. Is there any private test I can do that will prove that they are fine it is just nature or idk. My ds2 is asking why he isn’t growing and I honestly don’t know I really thought he would he is lean and eats well. I said it doesn’t matter what height they are but it’s hard when there are girls on both sides of our families who are much taller. I feel there is something at play here. I would especially love to hear from health professionals or anyone with similar experience. Thank you
