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?

You've gone from 0 to 100. Your mum is wrong but going no contact should be only used in extreme circumstances in my opinion

alcovecupboards · 27/09/2026 19:22

I think there are two issues here. One if your mum over-stepping and putting your son at risk of developing an eating disorder. The other is you failing to feed your child correctly. No child should be fat. It's a shame your mother has to trample on your boundaries but you're failing your son here.

SnappyPenguin · 27/09/2026 15:25

Yanbu. Your right keeping her away she will destroy his self esteem and then his mental health.

Meanwhile the kid grows up to be obese and unhealthy and ends up hating himself for that… while grandma is 100% wrong, so are mum and dad.

MangoMusique · 27/09/2026 19:27

I think people have decided he must be much bigger than he actually is because I won’t post his measurements. I’m not going to put an 8 year olds height and weight on here just so people can decide whether I’m a bad parent. I have put them into the NHS calculator myself and I know roughly where he is. I’m not ignoring it and I’m not sitting watching him get bigger and bigger without doing anything.

I’m also not going to accept that having a packet of biscuits or crisps in the cupboard is child abuse. They are family foods and the children don’t have unlimited access to them. I can accept that maybe we could have fewer treats or make different choices, but some of the comments on here are getting ridiculous.

I have changed some things already. I’m being more conscious of snacks and portions and making sure he is still active. I just haven’t put him on some strict diet because he is 8 and has gained some weight. I don’t want food to become a battle or for him to think he needs to be thin to be healthy.

I’m not trying to punish her forever. I’m angry because I had already told her more than once not to talk about his weight and she did it anyway. If she could just say she was wrong to say it directly to him and agree not to do it again, I would be much more comfortable with them seeing her. I just need her to understand why it wasn’t ok.

My DS is 8. Very active, normal eating habits. Size 8-9 trousers are a little big on him on the waist( fine on the leg). Yes all kids are different but your DS is wearing 2 sizes bigger. Have you put his measurements into NHS BMI calculator? You’re being vague about how big he actually is which makes me think maybe your mum has a point (even if the delivery isn’t good).

The clothes size isn't really relevant without knowing the height though. My just turned 7yo is in mostly 8-9 clothes and a couple of 9-10 tops but he's very tall and slim (133cm, 25kg). I agree it's kind of hard to comment without the OP sharing height and weight. But if he's overweight she could both tackle his diet and expect her Mum to respect her boundaries. Not worth long term NC IMO though.

ThisFridayNight · 27/09/2026 19:33

YANBU. She will damage his confidence & self esteem. A family member was doing this exact same thing to my now teen when they were younger. It didn't matter how many times I asked them to stop, they wouldn't. I took a step back and stopped seeing them as often and kept my kid away as much as possible. My teen says they remember the person used to make them feel sad as a kid but they don't remember what the comments were - it was comments about how much they were eating or how they "enjoyed their food" and calling them names like hungry horreous, teachers pet etc. They don't have a relationship with this person at all anymore. I wouldn't cut contact completely if it were me but I would have a talk with your Mum and I would reduce contact and i wouldn't leave your kids on their own with her as she can't be trusted not to voice her thoughts and opinions.

Marieb19 · 27/09/2026 19:34

I comment as someone who has had a lifetime of weight issues. Your husband and your son are both overweight and overeating. You know they are. You are making excuses for it (they're just big) and then blaming your mother for trying to help, even if her comments were a little crass. There are different schools of thought around how these conversations are best managed but your cutting your children's contact with their grandmother has more to do with your sense of failure than the welfare of your children. Your mother has been a very useful childminder for you but you won't tolerate any sense that you have let your children down, stocking your home with calorie and additive laden snacks they don't need. Your son will suffer a lot more hurtful and damaging comments (if he hasn't already) than those made by your mother.

Ritasueandbobtoo9 · 27/09/2026 19:36

I agree with your Mum. If he is fat, kids will call him fat, he will have low self esteem anyway. Ditch the biscuits, no kid needs them. Get him for. He will thank you.

NotrialNodeal · 27/09/2026 19:36

He's overweight and you are allowing him seconds and treats. I think overall you are damaging him more than his grandmother's comments.

Laurmolonlabe · 27/09/2026 19:36

Even if your son was overweight your mum is overstepping and you can't trust her to stop, so I think you have done the right thing. I remember comments my Nan made to me when I was your son's age with pain, and I am 64.

Dawninglory · 27/09/2026 19:41

Hi Op, Similar thing happened to my DS at 9yrs, after being a skinny Minnie! Suddenly he got puppy fat and it continued until puberty at 13/14. He started growing taller and by 16 looked stocky. Now at 18 he's 6ft and a mens Large, but all muscle. Kids bodies start changing at 8/9. Some of my DS friends hit puberty at 12. They are all different, if you know he's not pigging out on snacks all day, I wouldn't worry, tell your Mum that kids start maturity earlier these days and you have it in hand and it's not for discussion. End of.

Namemechangey · 27/09/2026 19:43

I have an 8 year old who is overweight, he has multiple things that cause this, including Autism, hypermobility etc. We speak to him about healthy eating, and are trying to limit portion sizes, questioning when he asks for seconds and not allowing another plate gen he has eaten plenty, limiting snacks or replacing with apples, cutting down on sweet things etc.
he is super sensitive about it though so we really have to be careful how we phrase things.
are you actively helping your son to manage his weight? If so have you spoke your mum about how you are doing this and what she can do to help and how she should approach it with him, what she can and can’t say etc.
it seems like grandma is concerned and rightly so, but the lack of communication between you and her about how you are approaching helping him to manage his weight might be the issue here.
Can you have a discussion with her about it? It seems bonkers to not let her see your son, you just need to come up with a joint strategy about how you can help him.

Unexpectedlysinglemum · 27/09/2026 19:45

I agree with your DH that she should agree to not mention his weight to him
again.
i also don’t think it’s a bad thing if your son isn’t sure about having pudding due to the weight gain, cutting out or reducing desserts is sensible and not eating disorder territory.

I’m sorry you’ve had a lifetime of weight issues but I don’t think you can know that dh and ds are overeating from a few posts on here. I’ve never said they are “just big” and therefore I’m doing nothing. I’ve said ds has put on some weight and I’ve looked at it properly. I know where he is on the calculator and I’m keeping an eye on what he eats.

I also don’t think I’m blaming mum for trying to help. If she had come to me and said she was worried about ds and wanted to talk about what we could do differently, I would have listened. She has every right to have an opinion. What I object to is her repeatedly making comments to him after I had specifically asked her not to.

And I don’t think I’m cutting contact because I feel like a failure. If anything I feel guilty as hell about stopping them seeing her. She has been a really important person to both children and she has helped me a lot. That’s why this is upsetting me so much. If I wanted to punish her I wouldn’t be sat here wondering if I’ve got it completely wrong.

I’m also not stocking the house with loads of “calorie and additive laden snacks” for him. We have biscuits and crisps because we are a family and sometimes we eat them. I’m happy to look at what we buy and make changes where needed, but I’m not going to pretend we have some terrible diet just because ds has gained weight.

And yes, he may well hear hurtful comments from other children at some point. That’s exactly why I want him to know that his body isn’t something to be ashamed of. I can teach him healthy habits without making him frightened of getting bigger. I don’t think grandma saying it to him was helpful, especially when he came straight to me afterwards asking if he was fat.

Hey....mumsnet.com......being fat is not the worst thing a person can be but it seems like the last hurrah of what is acceptable to mock, shame, insult and hate. I know that mumsnet is the home of teeny tiny salads, competitive undereating and more recently Ozempic but this is now seeping into hate towards children. Mumsnet has a real problem with fat people, poor people and people who are disabled and disadvantaged and I notice the reluctance to call this out.

Lottie6712 · 27/09/2026 19:47

My parents (who I do love dearly) I think significantly contributed to an eating disorder it took me a decade to shake with those kind of little comments from when I was about 6. "If you keep eating like that, you'll turn out like xyz, etc etc." if it were me, I'd say she can say anything she likes directly to you (I really value my family's input and definitely have changed things for the better from time to time with a really useful outside perspective), but he's too young to do anything useful with her somewhat passive/aggressive comments, so I think fair enough to stop contact unless she can stop directly saying things to him. I've directly told my parents to stop saying things like "you can't possibly still be hungry!" when my normal-sized children go for seconds! And they stopped immediately. So, I'd definitely protect your son in this scenario.

Rubes24 · 27/09/2026 19:47

This is a tough one OP and I dont think youre unreasonable to be angry! One of my grandmas alwasy commented on food and weight in realtion to everyone. It reslly effected both me and my sister and I still remember specific comments. However I adored my Grandma and would have missed out on a lot if I hadn't been able to see her. I think you need to sit down with your mum and talk about it seriously, explaining you are really worried about your sons mental health and eating disorders/ self esteem. I think you might need to reassure her of what you are doing to manage the weight and set some rules for what you can all do rather than say to help him. Ie the whole family only offered fruit for desert, no one having seconds (say food is all gone), the whole family does activities together. That way your son is not being singled out.

Shortbreadel · 27/09/2026 19:53

Well done on protecting your child

I know it is my responsibility to look after his health, and I’m not saying it isn’t. He doesn’t eat loads of rubbish all day, although yes there are biscuits, crisps etc in the house. He has normal meals, fruit, vegetables, drinks water and is at football twice a week. He’s also outside playing with his friends. I haven’t taken him to the GP about his weight because nobody has suggested there is a medical problem and he isn’t getting bigger and bigger like that. He has just grown and filled out a bit. I think if I suddenly put him on a diet at 8 he’d probably become even more focused on food and his body.

And just to clarify, I never said dh is very overweight. I said my mum made that comment about him. He is a bigger build but he isn’t massively overweight and weight/eating isn’t some huge issue in our house. We’re not sitting eating takeaways and sweets every night or anything.

With my mum, she can be unreasonable tbh and she is very blunt, but normally she does respect things I ask about the children. This is the one thing I’ve repeatedly asked her not to comment on and she keeps coming back to it, which is why I’m finding it harder to just brush off this time.

And yes, she was quite like this when I was growing up. She was always commenting on people being thin or needing to lose weight. She still does it now about relatives and people on the TV. I think that probably makes me more sensitive to it because I know how much it gets into your head. I don’t want ds growing up thinking being bigger means there is something wrong with him.

I do agree that dd shouldn’t necessarily lose her relationship with grandma because of it, which is why I’m struggling with whether I’ve gone too far. I just don’t know how else to make mum take me seriously when I’ve already asked her several times to stop.

You did the right thing, after asking her to stop again and again, you have shown her that you mean it. Having said that I would give her a second chance.

Talk to her on her own. A proper uninterrupted, serious sit down round the table, eye to eye, so she can't pretend to be washing cups etc. Remind her of the comments she's made, they add up. Remind her of your son's worries. Remind her how you felt when she did it to you. Remind her that this is serious, she needs to listen because if she continues to ignore you, you will not allow her to keep doing it. Remind her that its not her job to monitor your son's weight, its yours and you are doing that. You probably know best what to say.

Your DH's size is completely irrelevant. But seriously... Where is he in all this? I think you said he didn't want an argument. So he's kept quiet, leaving you to have one instead. Man up! It's his son too. It doesn't need to be an argument. It only needs to be a civil calm discussion. Asking her (on repeat if necessary) not to make these comments. But he can't linger in the background hoping it will all go away any more. Your DM is ignoring it because it's just you saying it. You are both his parents and your DH needs to be backing you up.

Would it help to shut her up if you got an appointment for DS with a dietician.. they are so helpful and understanding and most of all knowledgeable. They can tell you what is working well and what isn't. Then you can demolish any lingering comments with facts. They may also have advice on how to deal with this situation.

Sounds like she is stubborn though, so BOTH of you have to keep calling it out, each and every time.

But remember, DC change shape and size all the time between 8 and 16. Their appetites change, sometimes they seem to just peck, other times - hollow legs ( and usually after that there's a growth spurt which then explains it) and of course he's going to grow out of football shirts every year. You'd be worried if he didn't at this stage. Best of luck with this.

likeafishneedsabike · 27/09/2026 19:57

She has over stepped but maybe DS is actually a lot chubbier than you can admit to yourself. Your mum might be overstepping in her desperation to stop him ballooning.

Batcats · 27/09/2026 19:57

No your mum shouldn't have said what she did. But to ban two children from seeing a loving and involved Grandma is beyond cruel. That's going to cause them more harm than what was said to them and I'm amazed you can't see that.

Jacopo · 27/09/2026 19:59

I don’t know when it became the thing to say someone is ‘big’ rather than ‘fat’, but it really doesn’t help people address the reality of the situation. A significant majority of people in the UK are fat. Not big. Just fat. And the implications for their long term health are terrible.

Ohthatsabitshit · 27/09/2026 19:59

Tell her she can see them again when she can guarantee not to fat shame him.

TrueCrimeFanatic · 27/09/2026 20:00

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.
