I just think my son is going to be short. He’s 14 and 5’3”. It’s hard to know because he just started puberty. My doctor said that some kids grow 6 inches during their growth spurt and then a few afterwards. So that would make him 5’11” ish. Just sounds crazy that someone so small at 14 would turn out to be that big. He has really small hands and feet. Size 7!

Endocrinologist thinks he will reach 5’10’’ at a minimum. He was just slow and like another pp said, once he started growing, he really took off.


Why was he getting bone scans and seeing an endocrinologist? Is this normal for UMC people whose kids are below 50th percentile?


NP: my own DS was also 5’0” at 13, and we saw an endo at 13.5 (after bringing him in for a mid year height/weight check). In my DS’s case, he barely grew at ALL for over a year- in either height or weight- and was still tanner stage 1 (zero signs of puberty), which drew the concern of our pediatrician, as it can indicate other issues. In my DS’s case, it was simple constitutional delay- and he had an exaggerated period of very slow growth before puberty kicked in. Which apparently can be normal for some kids.

It isn’t always just about height alone. Also time is of the essence IF there is a problem. Many times there turns out to be no problem that requires treatment, which is great. But better safe than sorry. Especially if the pediatrician also has concerns.

My DS eventually started puberty and grew to a normal height without interventions, just later than most peers. But I’m glad we got it checked out.


This is OP. Our pediatrician wasn’t concerned when there were zero signs of puberty at 13. Nor at 14. Why was yours? At 15, he said it was most likely just a delay and ordered the bone scan. Now I’m wondering if we need any other work up beyond the bone scan.


Ours was concerned because of the growth issue outlined above. At his 13yo appt my DS not only had zero signs of puberty, but in the previous 12months had only grown 0.75 inches and gained 4lbs. So it was not just the lack of puberty signs but a general lack of growth entirely (after growing normally previously). Our ped was particularly concerned about things like celiac, growth hormone issues etc- which she would prefer to address sooner rather than later, if present.

My friend’s ped just referred their DS to an endo after no puberty signs at his 14yo appt. I think there is some variation as to when peds will refer out.


We had a daughter who had constitutional growth delay and when they go through a period of a year or two where they don't grow at all, it can be growth delay but it can also be a brain tumor or a pituitary tumor. It's not just "mom being weird". It's actually a bit scary and doctors are generally concerned until they can rule out some of these other issues. Our daughter had a bone scan as well, partly to rule this stuff out but also to help her parents stop worrying about these really bad reasons why kids don't grow.

Mine had no sign of puberty at all at 14 so the pediatrician ordered a hand X-ray to determine bone age.

We were referred to a pediatric endocrinologist which is how we knew. His bone age was 3 years behind. Sometimes peds refer for a bone age X-ray but it’s generally better to have an endo read it. But for a typical late bloomer there’s usually no reason to see a specialist.

Mine is finally growing at 15 and a 1/2. Was 24 months behind bone age at 13 but had started puberty. He is in late tanner stage now and likely to be close to his dad's height (5'11) but at one point was predicted over 6 feet based on tanner stage and bone age. I think last prediction was 5'10. He's 5'9 now.

He was short for ages and ages then suddenly medium, which is fine. Tall guys' hearts give out sooner.

My late bloomer is currently 6’1” at 16.5 and still growing. Also towering above the kids that grew early

Pediatrician thinks he’ll be at least 6 2 which tracks parental height. Younger brother is looking like he’ll have the same trajectory.


Great update! It sounds like your son grew 6 inches in 1.5 years and then will round out with 3 more inches! 5 ft 5 at 15 wasn’t terribly short to begin with though.


The issue was more about lack of puberty at 15, not height. And 5 5 for a child with very tall parents at 15 is small.

This is OP. My son is a high school sophomore. I’m not sure why you commented here or how it connects to my question.


This is an old post. I think the point might be is that half the boys are short going into high school and some girls tower over them for a short while. . The response was obvious to me.

Update - did your son grow to be a typical teen?


You literally posted this right after an update from OP.

Mine wasn’t exactly constitution delay bc he started just shy of 14. But he did have an 18 month bone delay.

While he reached his full height around 19, at 21 he’s still filling out.


This doesn’t make much sense. He started puberty at almost 14 and grew until he was 19! He must be really tall. Or a really slow grower. Or both, I supppse?

My experience: my son tested positive for growth hormone deficiency when he was 14. He’s finally experiencing puberty at almost 16. Just stay on top of it. I wish that I had recognized the issue a bit sooner.

Pediatrician at his most recent annual said “let’s watch it” but given family history of late growth plus no signs of puberty she said she was not concerned. Next annual is in 6 months so planning on pushing for additional testing if we haven’t seen more growth. DDs (older) both followed very typical growth/puberty timelines so this is very stressful—especially since he’s an athlete and now struggling to compete with boys who have already had growth spurts and are well into puberty.


In my family boys grow very late and girls are on time. Both are tall, in the end. Your daughters growth may be irrelevant here, though I’d be concerned re feet size without height.


Why would you be concerned about foot size without height? Our son’s feet grew a ton before they had their actual growth spurts. I thought that was the norm.


Yes I would think it’s a good thing that he has a 10.5 foot. My son is right around 5’ 3” at almost 14 and he wears a size 7!


Do you want feet to grow early or late to maximize growth?
