DS is nearly 10. He was born quite small but ended up quite a chunky baby and has remained chunky his whole life (if that’s the right word). He’s never looked overweight in my opinion just ‘solid’. He was always on the 91st percentile (not sure if he still is!) he’s in 9-10 and some 10-11 clothing so not in bigger size clothing.

He is around 135cm tall. And between 5.5 and 6 stone. We bought a second hand Wii with Wii sports. He was weighed just after eating a meal and wearing full school uniform at 5 stone 11ish so I’d say he’s probably about 5 stone 8 ish. The Wii has told him he’s obese - wonderful!

I was expecting overweight maybe but obese when he’s in the right size clothes for his age? Extremely active and eats fairly healthily!

How much do your 9/10 year old boys weigh?

Pop his details in to the nhs child bmi calculator which is online. I entered his dob as 01/01/2011 and that had him as overweight and on 91st percentile. Using his correct dob will give you a more accurate picture

My DS is 10 and the same weight, He is very tall though. 5f 2,
DS looks a little "softer" than i would like without his top off.. Not overweight yet but i think if he stopped doing all the sport he does, he has the potential to be.
He had a massive appetite though so I'm extra conscious of his weight.
Sounds like your ds is at least overweight based on that...

sirfredfredgeorge · 07/12/2020 17:40

DD is about 5cm taller and 6kg lighter.

Is he functionally fit, can he do a pull up, can he do monkey bars? ideally you'd want a junior parkrun or similar to find out how over 2km run too, but sadly they're still banned.

MrBloomsLeftVeg · 07/12/2020 17:42

I've a nine year old girl, same weight but in 12/13 clothing and 3.5 feet.

Waveysnail · 07/12/2020 17:46

Can you see his ribs? A healthy weight 9/10 you should be able to see their ribs.

Theworkwitch · 07/12/2020 17:48

I think it's ribs front and back, and no moobs. This is what I go by!

unicornparty · 07/12/2020 17:49

I have a 10 yo (11 very soon) and he's in the 8 stones! He's tall though. He runs 3-4 times a week and can run 5k in a decent time. He does hiit too so he's certainly fit.

Jjjjjj1981 · 07/12/2020 17:51

Honestly, I wouldn’t worry too much, he’s 9. Even in adults BMI should be taken with a pinch of salt, let alone children.
My son has just turned 9, is 5ft4 and 7 stone. He is not overweight or obese by any stretch of the imagination

reefedsail · 07/12/2020 17:53

My 10yo is 160cm and 7st which puts him on 69th centile on NHS BMI thingy. He's in adult small clothes generally.

He put on weight during lockdown due to losing all his sport, but has lost 4ish kg since it started up again. We are also extremely vigilant about snacks.

InTheLongGrass · 07/12/2020 18:12

DS2 is 9 and a half. Just converted 27kg to 4st 3lb.
His brother would have been lighter at that age, but was, and is, a nightmare to but trousers for.

Invisimamma · 07/12/2020 18:13

My son was also 91st centile when born. He is now 10, tall and thin, he weighs 5 stone and is 152cm tall, wearing age 11-12 clothes.

It sounds like he might need to be more active? What's a typical week's food like?

ChalkDinosaur · 07/12/2020 18:18

Personally I wouldn't worry too much about his BMI. I think in this context it's more important to consider whether he's eating healthily and how active he is. If you're (a d he's) happy with these things, great, if not then maybe tweak that stuff.

Tealuver · 07/12/2020 19:00

My son is 9 and a half. He is 136cm and is very lean, always has been. He weighs 4 stone

PenelopePiper · 07/12/2020 19:24

That sounds quite overweight to me.

My 9 year old looks like a normal, average child, maybe slightly tall for his age.

He's 4 stone 5 and 140cm tall (4ft 7")

Frazzlefrazle · 07/12/2020 19:30

My 9 year old is just over 4 stone ( only know as she had to be weighed for horse riding) not sure on height but she is average in her year group. Honestly I would say that it sounds over weight to me. Like others have said though what does his body actually look like?

As a side piece I was quite surprised at how many children were over weight in my other child's year 4 class in the virtual school play they did. I think a lot of parents don't seem to notice it however its so important to create healthy eating habits whist they are young.

BoomBoomsCousin · 07/12/2020 20:33

Getting a selection of other 9/10 year old boys' weights from people on the Internet isn't going to tell you anything about how healthy your son is. If you know he's 91st percentile for weight then you know that if you got a random sample of other kids' weights 90 out of a hundred would weight less than your son. That's what the percentile means.

He's relatively short for his age, but his weight is on the higher side of average. If your 5 stone 8 estimate is right he's at the very edge of a healthy weight for his height according to the NHS. These sorts of measures can't tell the difference between muscle and fat, so it's possible that he's healthy but more muscular than most kids, but he probably wouldn't look stocky if that were the case (because muscle is less dense than fat and so doesn't bulk you out as much for a given weight). If he looks stocky because he's got a lot of muscle, you should be able to see muscle definition rather than him just being broad and "solid" looking.

In any case, excess weight in kids is a significant, long-term health issue so it's worth contacting your GP to get an educated opinion you can rely on. Then you can make an educated decision about whether or not you should make some changes to your family/child's lifestyle.

As a culture we are still too complacent about how risky modern life in terms of making kids obese. Especially at the moment with the pandemic making most people more sedentary. It's easy to ignore the warning signals and easy to over react.

JesusInTheCabbageVan · 07/12/2020 20:42

What BoomBoomsCousin said. Also, parents of ribby beanpoles are more likely to reply, which will only make you worry more!

Devillishlypicklypickles · 07/12/2020 20:55

My 9yr old is 3.5 stone and 3ft 8, but she is on the 0.4th centile.

MrsTerryPratchett · 07/12/2020 21:06

And my 9 yo is 5 foot 2. Which is why asking ransoms won't work.

Is he fit, eats healthy, looks slim? If not, ask a HCP.

MrsTerryPratchett · 07/12/2020 21:07

The child in my house when best diet is also the one who has too much excess weight. Find it hard to keep up her activity level others seem to be moving so much more.
I'm always told to let her grow into weight so aim to work on activity more so that less food.

NoIDontWatchLoveIsland · 07/12/2020 23:30

My son is younger but I look at the kids in his preschool he see a LOT of chunky kids but their parents all describe them as "slim". But then all of them regularly give the kids a whole pack of crisps or mini cheddars as a snack. It's too many calories for a child of 3 or 4 years old

A junior school age kid should just be thin.

Unless they are unusually sporty they are unlikely to be truly muscled at such a young age. Being a normally active kid (playing football, riding bikes, swimming lessons etc won't make a child bulky with muscle.
