Anyone have a younger child taller than their older sibling of same sex?

Almost three years between my DS1&2. Totally different body types. Ds1 lean and sporty, and actually probably above average height for boys in his class. Ds2 born huge and stayed huge, head and shoulders above everyone in his class and a bit of chubster. Anyhow ds2 (nearly 8) is just half a head below ds1 (nearly 11). I think he may overtake him, unless ds1 has a puberty growth spurt asap.

anyone else had this? How did you deal with it? I feel sorry for both of them tbh - poor ds1 of younger brother towers over him. Poor ds2 everyone assumes he is older than he is.

same dad btw, who is tall, though ds1 looks like parental side and ds2 looks like my side, facially at least

I'm not minimising what you're saying as I realise height is somewhat important for men and older boys, but what does it matter? How many people compare the two boys? Probably only family. Everyone else will typically once focus on one of the boys at a time (friends won't care about a tall or shorter sibling).

There are so many kids with disadvantages out there, including learning difficulties, physical disabilities, really difficult home environments. That if having a taller younger brother is the biggest issue, then they're lucky.

DD2 (18) is about an inch taller than her older sister (19), and they're both taller than me. I get called Shrimpy!

It my kids but my BILs range from 5' 8" to 6' 4". The youngest being the tallest. Do t think it was ever much of an issue!
My friends youngest sone passed his older brother when he hit 10 and older boy 12 - no biggie there either.
Im the second daughter of three and im the tallest - 5'8" at 11 and kept growing - yes people thought I was older than I was but that didn't affect my sibling relationships.
I don't really understand what you are worried about.

Interested in this thread?

Yes I’m the older by 5/6 years, and looked after my sister whilst my parents went abroad for a month to deal with family stuff. I was twenty something and had to go in and speak to a teacher, who thought I was a younger sibling 🫠

Overweight children grow taller and develop more quickly, it’s excess hormones. Have you seen someone about his weight? I get people have different builds but babies are not born fat.

DD at 9 was a head taller than DS who was 11. It wasn't sn issue at all, we laughed it off if anyone mistook her for the eldest. He did overtake her after a couple more years.

My sister 2 years younger than me over took me in height at around 6. Now I'm shorter than all my younger siblings.

nokidshere · 18/09/2023 19:28

DS1 was the tallest in his class and head and shoulders above all,his friends from age 4 and was 6ft at age 12. DS2 (2yrs younger) was 6ft 2 aged 14 and still towers over his brother (and me) but seems to have stopped growing at 6ft 4.

Neither of them are remotely bothered about their height and none of them had any problems throughout their school yrs. they are 25 & 22 now.

This is just the same as my now 2 adult DD who although they are the same height are completely different body types. One is a flat chested size 6-8, the other a curvy 14-16, this is how they developed in puberty.

I have friends and family where the siblings don't go in height order after puberty. In younger children it is much rarer and I have only seen it where the older DC was a premature baby. My eldest DC was the tallest in their class by a head until year 2.

You could be describing my DS1 & 2 at the same age. They're all grown up now and the younger one is probably about 1-2cm taller, just over 6', broader of shoulder and a shoe size bigger. It doesn't bother them at all.

I often pop on mumsnet but never posted. Your my first response OP 😊.
I have 2 boys like you - 2 years between mine now 13 and 11. At about the age of 8 and 6 my two were the same height (the eldest is more petite frame my youngest slender but bigger built). They both have decent appetites/both energetic but my eldest just doesn’t gain weight as quickly and certainly grows at a much, much slower pace.
Anyway what I’m here to say is my boys have the best relationship I could ever want. They are equals in terms of their play fights (however, the younger would win really), they chatter and hang out, my eldest is ok with his brother interacting at times with his mates as he looks/acts as old as them, they are great buddies regardless of height and frame, they bring different personalities.
Some other mums made comments of which I just dismissed ‘everyone grows differently you can see they are a different frame’ - although I did worry just like you (inside I wanted my eldest to be the tallest I won’t lie and it hurt and I know my my eldest did feel it too from peers even teachers/other parents made comments at times too which was real hard).
Now both in high school I have let go of the issue, my eldest thinks he is Messi in the making 😆. My youngest does go to his older brother for support like his first day at high school last week (when I dropped them both off at high school I saw it🥲).
So let go of the worry, accept what is - it could change at anytime (my eldest hasn’t had a growth spurt really yet but I know it’s going to happen soon as he never stops eating😆). Your boys will be great for each other no matter what their size and at some point it won’t matter as much for either of you - just like me and my eldest now, it is what it is. Accepting is such freedom.

I have a 3&5 year old, they are the same height but my youngest is much bigger build than my oldest, he'll definitely out grow him very soon.
Oldest has always been small and skinny, whereas the second was born huge and continued to grow fast! They get mistaken for twins everywhere we go:

I am a mother of a son age 8 and a daughter age 6. Now my height is 5'1 and my husband is 5'5. So we are both shorter than average height. Also both coming from short families. Our son was always one of the shortest in his class. Well the shortest boy..he used to say that the only thing that annoyed him was that the girls in his class would always chase him at breaking which meant he was always caught. They would then hug him. His sister is 3 inches taller than him. Which is annoying as everyone think that he is younger. She can wear clothes that's her age. Our son has clothes for younger children. We have had him checked and it as cone out that he only reach 4'10 or 4'11. So we will see.
