Parents are biggest indicators of height.

We have known several kids who were very large for age throughout childhood. Off the top of my head, they all seem to have ended up more or less as you’d expect based on the parents. The tall ones all have at least one tall parent, I think.

None of my kids were 99th percentile but IMHO childhood percentiles really are not entirely predictive.

My kids:
DS19: was always 75th percentile for height and skinny, delayed puberty, now 6’1”
DD17: was always 30th percentile for height and barely on the charts for weight, now 5’7”
DS15: was always 60th percentile for height and 50th percentile for weight, now 5’10” and pretty sure he is about done growing

So- was somewhat predictive for my sons but not my DD. DH is 5’11” and I am 5’5”. Both families really average-ish (nobody super tall but also nobody super short)

Among their friends, we’ve know tall kids who just stopped growing early, ending up pretty average in height. But usually their parents are not tall.

My 6'2" boys were 90% for a long time, middle school they fell to 30%-50%....

They both had delayed puberty 8th grade for 1 and 10th grade for 1.

Both grew through junior year of college.

I was like that as a kid. Started puberty at 10, period at 11, and topped out at 5'7" by 12. Not sure what percentile that is, but I was supposed to be over 6'. My grandmother was 5'11", my aunt 6'0, brother 6'4". No clue what happened to me.

My 90th percentile boy stayed that way until around age 12, and started dropping, now around 60th at 14. But he hasn’t really started puberty (or just barely) and many other boys have had their big growth spurts, so that’s the reason for the drop. We’ll see if he goes back up.

DS hit 99th percentile at about one month an has remained there ever since. Almost 16 now.

Growth curves can move around. Neither of my kids are fully grown, but my son was 99th at birth and is nowhere near that now.

It’s too early to tell. I have 4 kids and none have stayed on their growth curve from age 2 — only one is fully grown, but at this point in time, 2 are taller than where they were at age 2, and 2 shorter. My 99% is now at 60%, but only age 10 - they stayed 99% until age 4 and then slowly started dropping each year (still growing appropriately, everyone else just growing a bit more, I guess).

Kid 1 was 99th as a baby/toddler and stayed pretty tall through a growth spurt around 11-12 years old. Now at 16, he’s below average height.

Kid 2 was always short (20th percentile) until growth spurt around 10, and is now average height at age 12 (girl). So it’s hard to tell much from early data.

I think it just depends. I was always a 99 percentile kid and am still about that for an adult woman. My son is like yours, also 6 — we’ll see. His older sister fell off a bit around 2/3 but is still 90+ at 8. My husband is tall too. Anything can happen but if parents are tall it is more likely to stay true for kids.

I have had 2 kids in the 99th percentile. Kid one (girl) was in the 99th percentile until she was 2 and then fell off to the 50th percentile and has stayed there ever since (now 11 years old).

Son (6 years old) has never left the 99th percentile for height or weight.

Just wondering if we should expect him to stay there or if big kids usually fall back to normal percentiles later.
