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?

Sorry, you shouldn't be having regular sweets & biscuits in the house. Kids of that age don't need this in the house :-(

caringcarer · 27/09/2026 16:14

If he's 8 and often wears 9-10 years he does sound bigger. That could be taller but could also be overweight.

You do realise some shops run a bit small, or he could be almost 9? It’s not like he’s in huge clothes for his age! My DS is 10 and has some 11-12 clothes as he likes them baggy or the legs are too short in his size.

Some of the judgements on this thread are crazy, and yes your DM overstepped and these kind of comments could lead to an eating disorder. Maybe give her a week or 2 to reflect and then have another discussion.

LAMPS1 · 27/09/2026 17:43

I can’t really tell whether your DM is being out of order or not, by saying what she did.
She was wrong to mention it again after you asked her not to but how do we know she didn’t do that because she felt you still weren’t taking notice of the signs of him becoming overweight.

His sweater and trousers are too tight. That’s a fact you sort of admit.
So that’s not good but it seems you aren’t concerned enough to say …yes mum I do think I might now need to stop having so many crisps, sweets and biscuit type snacks in the cupboard for them to help themselves to.
Instead you stopped her seeing him and his sister. A massive overreaction to my mind.

Your anger about this is out of proportion to the comments. Do you think there was malice in her comments or was her intent to be helpful, because you describe her as being such a lovely close grandmother so it would be odd if you felt it was malicious.

Is your son more upset and confused about not being able to see his grandmother than about what she said about healthy eating?

I don’t think this fall out should be discussed again in front of the children. I think you should accept that you over reacted and tell everybody that things are going straight back to normal this coming week…. it was all a storm in a tea cup.

Have a word with your mum privately and tell her you have DS’s weight and his overall health education well under control thank you and therefore there is no need to inadvertently shame him with any personal weight comments again.

Mischance · 27/09/2026 17:48

Your mum needs to be guided by you about parenting decisions and if she has persistently ignored your requests not to do something then you are entirely right to be very annoyed.
The size of your son is not relevant to the conversation ... her decision to ignore your wishes is the real issue.
And it means that however much your children love her and like being with her .... I am sure she does a degree of granny spoiling as we all do ..... you will always be worrying that you cannot trust her to do and say the right things. Not being able to trust her is very difficult indeed for you as there is no easy solution.
If you speak to her about it she will become defensive and you will still not know for sure if she is not undermining you when you are not there.

But that really is the only way forward. A very firm conversation about trust and about who is the parent here. You can give her another chance with the proviso that if she steps out of line again that will be it.

I am sure that you have your own strategy for dealing with the potential problem of your son's weight. Your mother needs to know this and that one of the aspects of this strategy is dealing with it without drawing his attention to it as you know this could be psychologically damaging and counterproductive .... tell her she must be on board with this approach or you cannot have her involved with the children. Also tell her very clearly that involvement with them is conditional upon her respecting your parenting decisions as paramount. And that if she has any problems she should talk with you privately away from the children.

By the way one of my GSs became noticeably plump at about the same age. His parents made no comment but just took great care about his diet and involved him in exercise. And there were no crisps or biscuits in the house. He is 14 now and the problem has resolved. He will never be slim because of his innate build but he is not overweight.

AllTheChicken · 27/09/2026 17:55

The way your mum is talking to him is how people end up with disordered eating and eating disorders, and theyre both far more common than people think.

OctoberMists · 27/09/2026 17:58

Let her see them but be there and be around and run interference or be very blunt ii fany comments are made. It's track I took with IL - and kids learnt to push back themselves.

MIL would make comments occasionally about weight or food intake - often just before a growth spurt - and also try feeding them crap and not make any connection that was unhelpful. Only think is to pollitely push back and say stop it - and let kids see you doing that and shut down any comprasions that hurt kids as well.

Weight wise some kids do go out before up - other are a bit cubby and the advice is to improve diet with little drama in background and keep them active and let them grow into the weight as dieting not recommended for kids - MIl was often dieting and struggled to understand that kids had higher needs for fat soluable vitamins than she at other end of life did.

SuchiRolls · 27/09/2026 17:59

Why do people read the OP post, and then do the exact thing she asked not to do? Bizarre. The weight of her son is irrelevant. You asked your mother not to address it in the way she was and not directly to YOUR son. Period. She continued to do that and then is surprised when you set a physical boundary after she ignored your set boundaries again and again. That is the issue. It’s a shame that SHE ruined that connection with her grandchildren and forced you to set another boundary until she could behave like a considerate adult with YOUR children. Why would she single him out and embarrass him? Those are moments to educate, it belittle him. And even when you set those boundaries and made it clear you didn’t want it to be addressed in that way, she continued and even dragged his dad into it. Ridiculous behaviour.

I have 3 boys. All 75th percentile and above at birth, all larger than average build as are all of the males on my husbands side. They seem to gain and then shoot up in height in cycles…because you know, hormones. That’s naturally how they grow? And have always been 2 sizes ahead of their age. If he was 2 plus stones overweight then yes, that’s a concern to be addressed by his parents which you seem to be on the ball with OP. Also if he is closer to 9, then that’s when puberty can start in boys. There can be early onset puberty also before 9. This seems a pattern of behaviour for your mother and it may have been overlooked when she was raising children but it’s not to be overlooked now.

pinkyredrose · 27/09/2026 18:02

Cut her some slack, she's just worried about his health. Why won't you post his measurements, it's hardly outing!

You do seem slightly in denial though. Btw football twice a wk doesn't mean he's that active, many kids spend most of the match walking or standing still! Is it school football or extra curricular?

Jintx · 27/09/2026 18:06

I mean this kindly OP but don't minimise the weight gain. It must be enough for her to comment. My mum minimised my brothers weight gain at that age from snacking, and he was bullied relentlessly and has struggled with image and self esteem ever since. I wouldn't stop them seeing her but you have to make it clear any weight comments are made to you.

grindergirl · 27/09/2026 18:09

A fat child is usually an unhappy child. That hasn't changed throughout the decades. I was a fat child, which isn't surprising. My own parents came through the war years, and after rationing ended, every day involved man-sized portions of breakfast, dinner, tea and supper. Relatives said I was 'bonny' rather than fat, but I knew what the euphemism meant.
One day at junior school we all got weighed and I was the heaviest child in the class, heavier than all the boys. That felt shameful. I only started losing weight as a teenager. Most mornings I wrapped up the toast or pikelets in toilet paper and chucked it over a hedge on the way to school. My lunch, which I insisted on, was 2 Ryvitas and a bit of blue cheese.
I now bite my tongue about my great-grandson, even though my daughter and grand-daughter continue to do him no favours. Junk food like chicken nuggets, crisps and fizzy drinks, 'treats' every single day. The 11-year child is huge and having to wear clothes that are for teenagers.
They insist it is a 'growth spurt'. Too many parents seem to want to deny that they don't have fat kids. The real cruelty lies in producing a generation of incredible hulks. Not from mouthy grandmas who know the misery that over-eating leads to

Bellaphant · 27/09/2026 18:09

My mum is really weird about food and weight (I think actually because people used to compare her to a relative when she was little, who was hugely fat, and my mum internalised the wrong thing...). As well as having to be fairly blunt about what she says around me - she'll often tell me about losing or putting on the same 3 pounds, or being 'naughty', etc - I have been really clear that the kids don't need to hear it. And I will repeat that, almost to the point of rudeness if she does - because I know she's being unreasonable. I've also had separate conversations with my kids (4 and 7) about nana being weird about food, different body sizes, being healthy enough to run around, etc.

Ilmiocompleanno · 27/09/2026 18:15

Re your Mum, I don't think you should stop your DC seeing her forever, but I think you do need to be clear that her barrage of comments direct to DS about his weight needs to stop (regardless of whether he is actually overweight or not). I would suggest that you meet up for a couple of hours with the DC and your Mum, but don't leave her alone with them. Meet up at a time that isn't a mealtime, so that there's no need for the conversation to be about food at all. Have a conversation with your Mum in advance (out of earshot of the DC) making very clear that if she brings up the subject of DS's weight or eating habits in his presence you will immediately leave with the DC. And mean it.

As for whether your DS is worryingly overweight or not, it's very difficult to tell from this thread. A lot of posters seem to be assuming that's the case, but as your Mum sounds quite weight-obsessed, it really doesn't sound like she's a good judge of whether there's an issue. If your DS is taking part in serious football training a couple of times a week and having no difficulty keeping up with the other kids, it doesn't sound to me like there's a huge issue. But do be honest with yourself. At age 8 I would expect your DS to be outgrowing clothes due to height. If you find yourself having to buy him new clothes due to an expanding waistline when they would still fit height-wise, that suggests to me that there could be an issue.

Your son wants to see his grandma. Believe me when I tell you that what is going on in his head is that he'll be able to see grandma when she doesn't comment on his weight and that the easiest way to make that happen is to lose weight. Your reaction is the opposite of your intention.

We’re talking about an 8yo here.
If someone needs to buckle up because he is overweight (and that’s a big IF), then it’s the adults around him, includimg the gran.

If she feels he has eaten enough, she shouldn’t make a shaming comment about how he is gettimg seconds. She shouldn’t make a say No and propose dessert and make it healthy (a fruit, a yoghurt).

He is a chikd, not an adukt. Not even a teen.

Bearbookagainandagain · 27/09/2026 18:25

I think you're both unreasonable ultimately.

Your mum should not be making those comments to your son, but you shouldn't keep telling yourself everything is fine if his clothes are getting so tight he needs a new size because of his waist rather than his height.

None of you seem to be willing to help him, I feel sorry for your son.

MangoMusique · 27/09/2026 18:29

I’m not refusing to look at his weight or burying my head in the sand. I have measured him and I know roughly where he is, I just don’t want to put his exact height and weight on a public thread about him. I don’t think that’s unreasonable. He’s 8 and I’d rather not have strangers discussing his exact body measurements.

And the 9-10 clothes aren’t tight on him. Some shops he wears 8-9, some 9-10, and the sizes are all over the place anyway. His school trousers are 9-10 because the 8-9 were getting short. That doesn’t automatically mean he’s massively overweight.

The football is an extra curricular club twice a week, proper training, and he plays outside with his friends as well. I know that doesn’t mean he is running around every second of the day. I’m not claiming he is some elite athlete. He just isn’t sitting in front of a screen all day either.

I also don’t think I’ve said anything about his weight being irrelevant. I’ve repeatedly said I’m aware he has put some weight on and I’m keeping an eye on it. What I don’t agree with is my mum making him responsible for it and telling him he needs to watch what he eats. I have already told her not to do that.

And yes, I probably am more defensive than I would normally be because this is my child and I know I’ve got things to think about too. But I don’t accept that because he might be a bit chubby, grandma gets to comment on his body directly after being specifically asked not to. Those are two separate things to me. She can talk to me privately if she’s genuinely worried.

It doesn't matter how much football he plays if you and your mum are allowing him to eat rubbish.

Stop buying rubbish. I don't know why you think it is ok to buy biscuits and crisps. Don't you listen to any nutritional advice?

Yes, I know. What's your point?

I think you've misunderstood mine. I meant that the child is going to think that the best way to solve this is to lose weight, regardless of what his mum says, because he still wants to see grandma. I'm not saying that he should lose weight. I'm describing what the child is thinking. By preventing contact with grandma, the OP is creating a problem that the child will want to solve - the opposite of her intention.

Quizzicallyspeaking · 27/09/2026 18:40

I'm not going to dictate on what you should or shouldn't allow your ds to eat. You know what amount of snacks are too much.

What I wouldnt do is ask your mum to apologise to him for her comments. It'll just make it into a big issue. Speak to her on her own and explain you want to handle his nutrition your way just as she did with you( well, maybe not in the same way from what you've said!) Just that its your responsibility not hers, she's had that when you were little.

firsttimepregnanthelp · 27/09/2026 18:40

YANBU these comments can be so damaging and it is not her place to intervene. She shouldn't be speaking negatively about anyone's appearance - that of your son or your DH. You are doing the right thing by protecting your son.

Also if your DH is heavier set it is entirely possible that your son will be too - this is genetic and not something easily controlled by diet and exercise. Please ignore the posters who are critical of what you are feeding your son - that is not the issue here.

MCF86 · 27/09/2026 18:41

People still don't get it. It doesn't matter if DS is 15 stone (well it does but not for this particular AIBU), Grandma still shouldn't be shaming HIM about it. He is 8!!

nutbrownhare15 · 27/09/2026 18:41

I expected to disagree with you but actually I totally agree as she isn't listening. She has to understand that you are the parent and what you say goes. This guide may be useful on what to say to your son. Who knows she could even read it to get a sense of why what's she's been saying is wrong. Not sure she would get it though. https://www.bda.uk.com/static/b5f71895-ed55-4a3e-b1dd93adb7210ecc/04cd5a26-e224-4202-baa15dbf7bc6ac84/talking-to-children-about-weight-guidance.pdf

Agree with this. Not wanting to put his height and weight on an anonymous forum is denial (if posted now I would expect them to be massaged a little). And being vague about portions and snacks, while mentioning "another helping" as if it normal for children to regularly have another helping.

I think the irrational anger and punishing her mum is to avoid looking at her son and ultimately the parenting that has led him to be overweight at such a tender age.

OP whatever happens with your mum, you son needs your support as it will impact so many aspects of his life if he is bigger than his friends, especially if he enjoys football and wants to be in the more teams when he gets older and it get more competitive and they need to be more agile.

Pabbel · 27/09/2026 18:48

She approachec the weight subject insensitively, but its a shame to keep her and the children apart when they obviously love each other.
Maybe a quiet word in her ear might help.
