Your son started 6th grade at 4 foot 2?

Damn.


Yep. He was the smallest 5th grader in ES including the girls.



Oh and he has purple stretch marks all over back. They’ve faded a lot though. They started on the left side of his back halfway down and then went down the left side and up the right side from the bottom. Like starting at 9pm on a clock and going counterclockwise until the went all of the way around back to 9pm.


That’s what happens when you have rapid growth spurts. My 18 year old niece is 5’8”, very thin with a waist at about 24”. After it seemed her growing was over her breasts grew very quickly to maybe a C/D cup and she got deep purple stretch marks. They have faded too but it still sucks. It’s pretty common though.

My son was 53.5 in (or 4 ft 5.5") at his 10 yr checkup. He was always the smallest in his class. At the end of 8th grade he was 61.25 in

He's now close to 6' at age 20.

A lot depends on when he started puberty. If your son grew 12" in MS, then he started on the earlier side. My son hit puberty in 10th grade (during covid). He had a glow up during covid. Even the bus driver barely recognized him when they went back to school from covid, and the kids in school thought he was a new kid.

I tracked all their height, weight, vax after a doctor's appointment in a spreadsheet. I also track my lab results in a spreadsheet.

My own son is a slow and steady kind of fella but he did have a little spurt of about 4-5" over 18 months or so. He's always been on the taller side and is 6'2" at 15.5. I'm guessing he's close to done.

DH is close to 6'3". He had a massive growth spurt at like 16 and has the stretch marks to show for it.

DS was a slow and steady, the most he grew in one year was a whopping 3". He started freshman year in HS at 61.25", was 70" at HS graduation, and is now close to 6' at 20 years of age. I think he's done growing.

Both were late bloomers.

I remember it bc my pediatrician expressed concern that my DS hadn’t grown for an entire year, and referred us to an endocrinologist.

Once growing starts its typically 3-4 inches for 3-4 years

I have two boys, and they had similar growth patterns. Through elementary, they were always "average." Freshman year of high school, they both grew from 5'7" to 6'1". One of them slowly added another inch; the other is up to 6'3" and might be done, but maybe not!

My DS was the shortest in his friend group until late MS, early HS when he grew around 6 inches over the course of two years. He's now 19 and topped out around 6'2 "or 6'3" - his poofy hair makes it hard to tell how tall he is without measuring.

My spouse is 6'3" as are most of the men in his family. He was teased for being short in 9th grade, but then grew 6 inches in 6 weeks the summer between 10th-11th grade. He was 6' when he graduated 12th, but grew another 3 inches in college.

My 10th grade son grew 5 inches in a year between the summer before 9th and summer before 10th. Has probably grown two inches since, too.

My son started his growth spurt at 14.

It was pretty slow and steady, he went from just over 5’ (right before turning 14) to 5’11” after his first year of college, and stopped there.

My 14 year old (will be 15 in about 6 weeks) has grown 4 inches this year.
