To stop my mum seeing my DS after what she said to him?

NC because this is quite identifying. I’ve got ds who is 8 and dd who is 5, and my mum is their grandma. She has always been very involved with them and normally has them every other Saturday, sometimes picks them up from school and takes them out. They absolutely adore her and until now I’ve always thought of her as a really good grandma, even though she can be blunt sometimes. I’ve stopped her seeing them for now because of something she said directly to ds and I’m not sure if I’ve overreacted.

ds is 8, in year 4, loves football and gaming and is a quiet sensitive child. He’s doing fine at school really, not especially academic. He is bigger than some boys in his class and has put on a bit of weight recently, but he isn’t obese and isn’t under any weight management or medical care. I don’t want this to become a discussion about whether he technically needs to lose weight because that isn’t what I’m upset about. Me and dh encourage him to be active and we eat normal meals, with treats as well. He’s just an eight year old.

My mum is 62 and retired, lives about 20 minutes away and has always been there for me and us. She buys them little things, takes them swimming, to the park, shopping, whatever they fancy, they look forward to her weekends. She has helped me out a lot and the kids see her as important too. My dad died a few years ago and my brother lives abroad so there isn’t another grandparent nearby who could fill the gap. I’ve defended her before by saying she’s their grandma and she’s always been there, and tbh she genuinely has been loving and involved with them.

The problem is she has got increasingly interested in ds’s weight. She’s asked him why he always wants seconds, told him he needs to watch the biscuits and commented that his school trousers looked tight. She’s also compared him to slimmer cousins and asked me if he gets enough exercise. I have spoken to her privately and said please don’t talk about his weight in front of him. She says she’s only concerned because children don’t know when to stop, but she carries on making comments. Dh has noticed too but normally just says that’s your mum and doesn’t want a huge argument.

Last week ds came into the kitchen wearing his school jumper. He’d been asking me about getting a new football shirt because his old one was tight. Mum looked at him and said, “you don’t want to get any bigger, do you? You’ll end up like your dad.” He just laughed awkwardly and I didn’t make a thing of it. Later that same evening he quietly asked me if he was fat. I honestly felt sick because he hadn’t used that word about himself before. I asked him why and he said grandma had told him boys get fat if they eat too much rubbish and need to be careful.

I rang mum and asked what she thought she was doing. She said ds had misunderstood her, then said she was only trying to help him. She said I was being too sensitive and that if nobody tells children anything they’ll become unhealthy. I said there’s a difference between teaching healthy habits and making an eight year old think about whether his body is too big. She said I let him eat whatever he wants, which I disagree with that. We do have biscuits and sweets in the house, but he eats meals and he’s active. Mum said she was giving sensible advice.

It also isn’t just this one conversation, so I’m struggling to see it as harmless. There have been the comments about seconds, biscuits, his trousers and exercise, and she has said things like he eats like a grown man. I’ve told her before that I don’t want her discussing his weight with him and she had agreed, so she knew. Since last week ds has asked me if he should have dessert and asked whether his new football shirt I want to buy will make him look bigger. Maybe those are coincidence, but it feels like something he wasn’t worrying about before has got into his head.

I told mum she isn’t going to be seeing either child for now. She said I was being cruel and using the children to punish her, and she has told relatives that I’m keeping her grandchildren away over one harmless comment. I said it isn’t one harmless comment, it’s the final one after months of smaller comments that I had already asked her to stop making. I know that sounds dramatic because she hasn’t been a bad grandma in every other respect. She has actually been a very good one. But I’m angry, and I don’t trust myself to just carry on as normal.

Dh thinks mum was wrong but doesn’t think I should have stopped contact at this point. He thinks I should tell her she can see them again if she apologises to ds properly to ds and agrees she won’t talk about weight with him. Not sure. dd keeps asking when she can go to Grandma’s and I feel awful because she hasn’t done anything. The really awkward thing for me is ds himself says he still wants to see grandma. He loves her and still talks about going there. I haven’t made him choose sides at all. There really isn’t another nearby grandparent for them.

I don’t know if I’m protecting ds or letting my anger make this bigger than it needs to be. I don’t want him growing up worrying about his weight, especially at eight, and I had made the boundary clear. At the same time I don’t want to take away a relationship with a grandmother he loves because she said something badly, not deliberately. The children adore her. Maybe tbh I am being too sensitive. AIBU to stop my mum seeing both children after what she said to ds, even though she has always been a good grandma otherwise?

I absolutely agree that your mum should not have made comments to DS and I would have come down hard on this too. Poor boy asking if he’s fat.

However, this really needs to be a wake up call to you. DS is upset after his granny made a comment but this will be far worse after comments from his peers in school if you don’t make some changes to his diet and lifestyle now.

My DS is 5 and I’m always conscious of his diet and how much exercise he is doing because I know that everything in school and beyond is so much easier if you are fit and healthy. He has peers who are a little more overweight and it is noticeable in their differing confidence, even at age 5.

It’s perfectly fine btw to say no to seconds and direct him to a banana if he’s still hungry. In general, I’d really try and get rid of all snacks/desserts on weekdays and save them for weekends only. I would also be wary of thinking two nights of football is sufficient exercise for an 8 year old boy. I would look at building in more activities like bike riding, swimming and even walking to and from school if possible.

What you suggest here is the opposite of how to avoid kids getting fat. I know your comment is well-intentioned but the work of nutrition expert Ellyn Satter shows that limiting seconds (of savoury healthy meals) and limiting treats until the weekend makes kids more likely to overeat and have a poor relationship with food in the long run.

When my DD was 4 her daycare said she was chubby and we should try to do something about it. I limited helpings at dinner and banned sweets. Her weight ballooned - she ended up eating more in the daycare and bingeing whenever she was at a party or a friend's house.

I bought the Ellyn Satter book (recommended here on MN). She got a small treat for dessert every day and unlimited helpings at meals, which were healthy, but if she wanted 3 plates of pasta and no veg it was allowed. The first 2 weeks she overate, then as she realised there was no need to because she was allowed to take what she needed, she calmed down. She's 11 now and very slim. She loves healthy food but also likes treats. She associates food with pleasure, not guilt. I'm so, so glad I didn't limit her and instead let her learn to regulate herself. Children need to learn to listen to what their own bodies need because once they're out of the house and mum isn't there to make all of the decisions, a child who is denied food is going to overeat.

Summerhut2025 · 27/09/2026 20:49

Well it’s better than him being bullied at school when he becomes overweight, sometimes things just need to be said bluntly for them to hit home. Keeping your kids away from their grandmother is just cruel, I’m pretty sure she won’t mention the weight thing again but don’t bury your head in the sand OP if he is over weight, nip it in the bud now.

Mamma18282 · 27/09/2026 20:50

OP I would focus on what your mum should do to repair things and how you can help her with that. Work out a script of what you would like her to say when she apologises to DS and ask her to do so with you present. And obvs be very clear that she is not to discuss weight with DS again. She could instead focus on more positive ways to eat healthily when he’s in her care and that probably means no treats in her house, and then it’s easy to say “I don’t have crisps and biscuits” rather than “eating crisps and biscuits will make you fat”.

She’s unable to see what she’s done wrong so the best you can do is help her along.

Exactly. What happens when he is told that he is fat at school? Are you going to keep him away from school too?

daisychain01 · 27/09/2026 20:51

Why not get your 8 year olds weight under control, that's the root cause of the whole issue.

get rid of "treats" and crap food from the house, serve tasty meals and no snacking.

child happier no more comments from grandma, and child learns healthy eating habits.

YourLoftyCyanZebra · 27/09/2026 20:51

Let's normalise calling out shitty people. That includes people that fat shame. It's never worked. GLP1 jabs have leveled the playing field but children are not fair game you shallow cunts.

Pennyfan · 27/09/2026 20:51

YourLoftyCyanZebra · 27/09/2026 20:43

If fat shaming children or adults worked, we wouldn't have fat people. Its the last socially acceptable hate.

Ridiculous. In Japan-very low obesity rates-you are told you need to lose weight quite bluntly if you get too porky. No one sees it as ‘shaming’ but reminding people they need to take action. We are where we are here because of many complex reasons-including not wanting to upset people by mentioning their weight. I worked in healthcare-we had the stupid situation where because we were too scared to ask people’s weight, someone collapsed a chair and hurt themselves.

YourLoftyCyanZebra · 27/09/2026 20:54

Pennyfan · 27/09/2026 20:46

It’s cruel to cut a well loved, close, loving family member out because she’s tactless and direct. Cruel to your son who loves her. Just tell him she doesn’t want him to be unhealthy so she goes over the top a bit.

Incidentally, while we are terrified of traumatising our kids by telling them they are overweight and need to eat less, in other countries they are far more direct and blunt yet they don’t have the obesity problems that we do in the UK.

Japan....the home of CSA, denial or war crimes and hidden cameras?

It is not comparable.
Asian culture is completely different!

Minasama · 27/09/2026 20:55

I think if your child is overweight it is better to acknowledge it and not allow him seconds or snacks. This can be easily achieved in such a way that you serve dinner straight to plates and no one gets the option of seconds.

It would be a huge shame to stop your mum seeing him when she is clearly worried about his wellbeing, however I agree it’s not fair to make comments about his weight to him because this is something the adults around him need to take in hand.

I would tell her - yes, you’ve decided it’s time to take action, he gets one portion of healthy dinner from now on and only toast, no cake/biscuits etc after school. However she’s not to mention the subject of weight again.

YANBU I have an overweight GD, aged 9. I can see she is overweight but every time I look at her I just see this beautiful gorgeous scrumptious little girl who I absolutely adore. If she’s with me and asks for food she gets it, I spoil her but it isn’t that often I look after her (maybe one a month) honestly I’m just so grateful to spend time with her and know she adores me too.

Her weight ( and yours sons) is a matter for themselves and their parents. Grand parents should not be getting involved unless asked for advice or help.

I'm sorry but you are harming your beloved grand daughter. You love to see her enjoy the ice cream, sweets, bag of crisps etc. But be honest, you are doing this for the joy you derive from seeing her enjoy this but you are not helping her. Maybe start to think about the decades she will spend at weight watchers or on Mounjaro because of the behaviours instilled in childhood.

juiceyoranges · 27/09/2026 21:00

If your son is overweight and you are not doing anything about it, you are doing your son a disservice. If you aren’t addressing it now, he will continue to put on weight and will get bigger and bigger. Your mum is speaking out of love and concerned for him. No kid wants to be the fat kid at school, but unfortunately they don’t have the discipline all the knowledge to control their eating habits. As a parent who loves their child and wants the best for them, you need to be the one to guide them and restrict their eating. If you’re not doing that, then it will be frustrating for others family members who love your child and want the best for them.
Sometimes kids need to hear harsh truths. You say your kid is active but if he is overweight, he is not active enough.

I say this as someone who has a close child family member Who has been overweight since around eight years old and the parents are not doing anything about it. The kid is now 12 and is classed as being obese, and has man boobs. No 12-year-old boy can be happy with man boobs and being the fat kid at school, but the parents don’t care enough to sort it out and to restrict his eating enforce more exercise.

I think you can speak to your mum about not hurting his feelings, but I think you need to address the Growing situation with your son because it won’t magically loose the weight and he will not likely grow into the weight.

SixtySomething · 27/09/2026 21:00

Awkwardisfunny · 27/09/2026 20:08

I agree with asking her to apologise to your son but maybe instead of "sorry" she tells your son that what you said. That she shouldn't have commented because XYZ. And to add on that if she mentions it again, she wants your son to let you know immediately.

Basically, you will be present while your mum enforces your boundaries in front of your son with you as a witness.

This is so weird.
A planned humiliation for your DM!
Wtf.
I’m used to the push to infantilise older women on MN but this really takes the biscuit.
Children get gentle parenting. DMs get punishment designed to humiliate and belittle. 😳

An 8yo's weight isn't causing an adult to tell the child directly he is fat. Frankly it's bizarre that you have reached this conclusion.

The GM's actions are her choice. It's not as if once a child reaches a certain weight, the only course of action is calling them out for it or the child will die. There are lots of other things the GM could choose to do, and has been asked to, but she won't.

Bababear987 · 27/09/2026 21:02

OP you are 100% head in the sand

An 8y old should not be overweight or chubby at all.
I used to work with a girl who talked about her son being 'solid' or 'big boned' etc but he was just fat. Children of that age shouldnt be chubby, its simply not ok. Babies and toddlers.. yes, primary aged children no.
It take the brain around 20mins to realise the stomach is full after eating so if hes asking for 2nds the chances are he's not actually hungry or needing that amount and its ok to say no to that or redirect to something less calorie dense. Its also worth remembering that just because dinner is homecooked or 'healthy' it doesn't mean he can eat unlimited amounts of it without putting on weight. Many healthy homecooked meals are very calorie dense and we've completely lost sight of normal portions.
Im not a healthy eater and love eating out, takeout, doughnuts etc but I dont allow the kids to eat biscuits or crisps everyday. We dont even keep them in the house.
I promise you (as someone who grew up always fat or overweight) I wish my mum had addressed it with me in an honest way. He will notice his weight and unfortunately so will other kids and you will cause him a lot more distress by not addressing this with him.

Two sessions of football a week is absolutely nothing for a boy of that age btw, i think its around 1hr+ a day they are recommended at that age.

Put simply hes eating too much and not exercising anywhere near enough and putting on weight.

Your mum has overstepped obviously but shes seeing you allow an overweight child to continue eating junk food and have seconds.

No one said it's the worse thing a child can be. But we do have an obesity issue here. It's not good for the nations health. So countries that don't have it are better for that

Jjjr · 27/09/2026 21:04

Tryamp · 27/09/2026 20:11

That’s correct. Don’t say anything.

So if they are on the track to obesity, health issues and diabetes better just to not say anything because it might upset them?

ReleaseTheDucksOfWar · 27/09/2026 21:04

There's a few things here.

Firstly, a LOT of posters are projecting their own issues. Youve said you checked his BMI on the NHS chart and its OK. That should be enough for people. You can ignore the posts which don't see / understand / respect that.

Secondly, comments like grandma makes can set a child up for years or a lifetime of eating issues. Youre not wrong to be concerned.

Thirdly, she's overall a very good grandma.

Fourthly ... she may overall be good, but she's manipulative. She's saying to extended family that you're stoppjng her seeing the grandchildren over one comment. It's not true, she knows it's not true.

I think that you need to speak to your son and actually, explain that weight does matter but it's a LOT more complex that Grandma makes out. Go into the science a bit - that according to the BMI, he's ok and that sometimes children put a little bit of spare weight on just before a growth spurt. That that's okay - you need it. How can you grow if you don't have the resources for it? That the problem comes if the weight stays on for many months / years. Point out that the BMI is a blunt instrument - some people without a spare cell of fat are at the top end of the BMI because muscle weighs more than fat.

Then I'd also explain that some generally wonderful people have a weak spot about some things, and grandma has that about weight. That overall she's a lovely and super gran, but in this one area she has a blind spot and it doesn't matter what she says about weight, he should only listen to you. This is important, because worrying about weight too much can lead to some bad things.

Talk to him about healthy eating, the components of healthy eating and where / how far you can eat less healthy things. Two bags of crisps a week in an active child isnt a problem. Seven is.

Its clear you quite reasonably want this to be resolved with your mum. I think youre going to have a difficult, very direct conversation with her. I think you're going to have to go and talk talk to her, and be very direct. Say that you know she loves them, but that you both know she has been ignoring your clear, repeated wishes regarding comments about weight. That she has been ... misrepresenting .... why the children have not been allowed to see her. Say, in words, that she has been telling people that it's because of one comment and actually, it's because she has repeatedly ignored your requests to stop making damaging and dangerous comments, and that you are angry. You have to speak your own truth out, or it will fester and never be resolved and left behind.

I think then that you should say that this is a situation you want resolved and that you want the children to see her again - all of you want that. Can she agree to park the weight concerns permanently?

You know your mum and what you can say - and how - and you'll need to adapt the suggestions here. But I do think you need to speak in a factual way to your son, and in a direct way to your mother, calling out her manipulation and stating that her undermining and manipulation has made you angry.

Either your mum will realise you're a grown adult too and she needs to respect that, or she will choose try to exert her will over yours. If that happens, you have another problem.

Good luck. Such a shame when a basically lovely relationship is threatened by someone riding roughshod over the parent, when the parent has a very valid concern.

OP, I disagree with forcing your mum to apologise to your DS, as I think that draws too much attention to the weight issue. The key thing is that your mum stops making comments to him about his weight/eating habits.
