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?

Boomers for you.

YABVU though so is your mum!
You say your son is active but he obviously isn’t or he wouldn’t be overweight; which will be having a detrimental effect on his health.
However…. The way your mum went about this, was absolutely disgusting. Fat shaming a child like that is bullying. She should’ve had a quiet word with you if she was concerned.
So neither of you are in the right here in my opinion.

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.

What does ‘trying to limit portion sizes’ or limit ‘seconds’ look like tho
I’m baffled by these comments..?

You dish his tea up appropriately, you decide a normal portion
He wants more you say No
end of?

Snacks ? ‘An Apple after school and wait till tea son’

‘But I’m hungry’ - that’s good son, you are supposed to be before a meal and will eat it all up then

Limit sweet stuff- what sweet stuff ? Nothing here in the house , birthday parties, and some popcorn or couple squares chocolate on Saturday with a board game /film etc

baffled by how hard it is for some people to not to have fat kids

ffs

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. 😳

You view apologising to a child as punishment? Or infantilising the adult?

Same mindset is why some adults think it's acceptable to ignore children like they're not present or tell them they can't go to the toilet at school when they ask. They have rights. Including the right to be heard and apologised to when insulted and degraded.

Ofcoursenot26 · 27/09/2026 23:54

Whether your son is fat or not your mother has been told, repeatedly, to shut her own fat gob and refuses to do so.

So yes, of course you must discipline her and you must tell your son she is being refused access to her grandchildren because she won't shut her abusive mouth.

Yes, adults do need to be disciplined when they behave badly. That's what social sanctions, laws etc exist for. So discipline her until she behaves better. A month away from YOUR children will teach her a lesson, if she keeps it up, another month away and so on until she learns her place.

Your son needs to know you have his back.

If he is, actually, fat, that's something YOU his mother needs to start addressing today. You have total control of all snacks and sweets, so if he's fat stop buying them. No processed sugar of any kind, wean him off all fast food and get him back on healthy foods.

Bridesmaidorexfriend · 27/09/2026 23:55

I’m torn, you’re not the overeacting at all but I would not ban her for long. Just long enough she sees you’re serious.

a kid in my area growing up was referred to as fat ‘Rebecca’, cruel and unnecessary but everyone called her it as if it were her actual name. I was out with my nan and I asked for sweets and she said you’ve got to stop eating rubbish! They will start calling you fat ‘bridesmaid’ soon. Devastated me lol. She died not long after and it’s one of very few memories I have of her. It’s all well and good people saying it’s because kids need to be told, kids shouldn’t be fat, but it does irreparable damage to self esteem. I’m sure it did for poor ‘Rebecca’ too

”Drama like yours” can you explain what my drama is?

You keep saying it’s quite possible the grandmother has tried talking to the mother, you’re assuming here as OP hadn’t said this. What OP has said is she’s asked the grandmother to stop saying things to her child, the grandmother ignored her.

“Grandparents also are entitled to be respected.”

Respect has to be earn’t, it’s is not just given because someone is a grandparent.

“It seems pretty obvious that she is acting out of concern for her DGS.”

By calling him fat?

“Children are usually expected to follow rules, not grandparents. They are old enough and wise enough to decide for themselves what's the right thing to do.”

I honestly can’t stop laughing that all grandparents are wise enough to do the right thing! also why are grandparents not expected to follow rules? Do rules suddenly not apply to people once they become grandparents?

“It's not really about respecting parents' wishes. It's about taking action when concerned.”

So the grandparent knows better than the parent? O yeah you’ve already said they know better 🙄

I will reiterate my original point, grandparents have no rights to access their grandchildren, I will also include they have absolutely no rights to parent their grandchildren.

If a grandparent wants to ignore the parents requests because as grandparents they are clearly “wiser” and care more about their grandchildren than the actual parents, then they run the risks of loosing access to those grandchildren because it’s the parents right who they allow access to their children. It dose not matter the reasons.

Your whole rant about the grandmother knowing better, being concerned, tackling it herself, calling a child fat and putting his Dad down screams toxic overstepping possibly abusive grandmother to me!

"Your whole rant about the grandmother knowing better, being concerned, tackling it herself, calling a child fat and putting his Dad down screams toxic overstepping possibly abusive grandmother to me!"

I don't really understand this.
Who is the "toxic overstepping possibly abusive grandmother ?"
Are you suggesting I'm that thing because I'm "ranting"?
Or is it Op's DM?
Your post suggests "very young person wth plenty of opinions and no life experience" to me.

Yes GPs are automatically entitled to respect, without earning it, because of who they are. So are DC and DPs. There is nothing wrong with this.

"Give your head a wobble."
People are expected to respect members of their own families because they are related.

user1492757084 · 28/09/2026 00:01

Your DM is out of line.
Explain to her that even if her grandson is obese she should not belittle his appearance.
Have her stay away for a few weeks.
Give her educated reading matter on the subject of body image and disordered eating etc.

Examine if she has a point.
Is your son obese?
Does he have unlimited access to junk food and biscuits.
Stop buying junk and display fruit and vegies in a bowl.
You need to have rules about polite eating in company too. No one needs more than two biscuits in one sitting.

Do mothers get to discipline' their adult daughters, too, when they insist on buying sugary snacks, until they learn to stop doing it?

This language is completely inappropriate to relationships between adult family members.

What we really need to do is include being Fat in the ever growing list of protected characteristics included in the Equality Act. May as well seeing as daring to notice that an overweight person eats too many crisps and biscuits, therefore making them fat, is a shameful thing and moreso if you vocalise it.

Oh dear this is extremely ill informed. Listen to Drs who state the biggest predeterminant for fatness is genetics.

Found the badly behaved, big mouthed grandmother. You're not the mother, you have zero rights in parenting the child, and you will definitely lose contact with HER children if you keep this up.

The correct response was to take her daughter aside and talk to her, not shame, bully and upset the child.

Overstepping grandma she has been told repeatedly to shut her fat, interfering gob. So now she gets to be disciplined, and remember her place.

You are definitely an overbearing grandmother who needs to learn her place before you lose all access to other people's children.

Sorry Op, of course this is a sensitive issue and you’re right really that your mum hasn’t handled it well.

It sounds like she really does care about her grandson’s health though and has not been making comments out of malice. I seems it’s become more worrying for her and she’s tried to get your DS to see the issues for himself.

I think it’s a tough one because she’s overstepped a boundary, but when you told her not to make comments, you didn’t reassure her you’re dealing with it you just said you were “keeping an eye on it” and so its also understandable she’s worried.

But it's not understandable that her mother is completely overstepping the boundary OP placed, repeatedly.

Her mother needs to re-learn her place, and stop sneakily calling her grandson fat behind his mother's back.

If she has genuine concerns the person to talk to is the OP. Meanwhile, some non contact time will remind her of her place.

GarlicSomething · 28/09/2026 00:30

@MangoMusique, don't defend yourself on here. I knew your thread would attract all the teeny-tinies and their diet issues!

Your mother fat-shamed you, she does it about strangers and to other family members. She'd be very comfortable among the massive salad eaters of Mumsnet 😬 Now she's inflicting her complex on your child, and you're right to stop it.

Children grow. Many children grow 'out' before they grow 'up'; this is a known phenomenon, especially in kids of sturdy build who will grow tall. My siblings and I all did, all my nephews did, and none of us have been overweight at any point since. Growth spurts need food!

In the rare cases where children have no exposure to disordered thinking about diet and ready access to food, they self-regulate their intake. Sounds like you're doing a brilliant job with your family, well done!

Tell DS he's growing strong and encourage his athleticism. Tell your mother IT DOESN'T MATTER what sizes her grandchildren are and what they eat. Tell her you're their mother and you won't have their self-esteem damaged as she damaged yours. I hope that does hurt her, she might learn a thing.

I love this reponse. I was a skinny minnie growing up, as were my kids, so I have no dog in this fight personally. But I truly loathe the emotional bullying and harassment of kids and I dislike the sort of women who think they can override the right of a loving mother to parent her own children.

Given Gobby Granny has already had many warnings, only going non contact for a time has any hope of getting through to her.

"And you won't have their self-esteem damaged as she damaged yours." is pretty much perfect.

Beenwhereyouareagain · 28/09/2026 01:38

It wasn't one comment, though. It was months of negative remarks and chronic trauma to his psyche. "Comments" like those stick with a child. He's 8; he's not stupid. He knows exactly what his "D"GM means whenever she says those things. He loves her and still wants to see her, but he'll also have internalized all of the horrible little digs she has made.

I might be wrong, but I imagine he is struggling to accept that the grandmother who's always been so loving is also the person who has shamed and hurt him the most. It's not about his eating habits or his size as much as it is about your mother trying to control you all. When kids are growing up, there are always awkward stages. It sounds like she's uncomfortable with the changes, but she needs to shut her mouth! All her help has done is convince him that he's fat, his clothes look too tight, and someone is monitoring every thing he eats. He'll believe her because he trusts her. In fact, he'll be convinced everyone sees him this way.

This is textbook for how eating disorders and self-esteem issues are triggered. I don't know how you begin to convince her how damaging her words and behavior are, but this has to stop. She's bullying him and your husband is dismissing it. He's not protecting his son- if he ignores it, he's giving tacit approval to everything your mother has said, and your son is taking that in.

I'm also sixty-something. Your viewpoint sounds like someone who was a parent in the fifties when you were just a child yourself in the sixties. I hope no one treated you this poorly although it was common when we were kids.

I'm sorry that you are unable to see how damaging that woman's behavior is to her grandson and to her daughter. Respect can be automatically given, but it should also be taken away when someone behaves so badly. And his grandmother, for all her good points, has behaved horribly to them. All the wonderful, loving things she has done do not negate the harm from this last few months.

Respect is not a tradition to be upheld, earned or not. It is a privilege that should be taken away if the person no longer deserves it.

Well, my ex mil told my 13 yo DD that she was fat - DD is already 5 foot 10 inches tall and is an adult size 6 (only know adult size because she is so tall that teen jeans & trousers are way too short). She won’t speak to her GM after that, even though she is the only GC that will still visit her, she doesn’t engage with her after that.

You'll douch more damage to your son emotionally by stopping contact with someone he loves than by hearing from her that he is overweight.

Just explain to him that your mum's generation were more concerned about weight and being skinny and that's why she says things. Remind your mum again to watch what she says. End of. No need for big drama.

Mainly agree with this. Slim should be a goal though. Eat everything in moderation. More veg and fruit to fill him. No seconds or snacks. Change the pattern. Set him a good example.

I had already said in the OP that he’s put weight on and that I’m aware of it. I’m not denying that and I’m not saying his weight is completely irrelevant. Obviously I’m his mum and if I think things need changing then I need to do that.

But I didn’t start the thread asking for advice on how to put an 8 year old on a diet or asking people to decide whether he’s obese. I was asking about my mum repeatedly making comments to him about his size after I had specifically asked her not to.

I can accept that his weight is part of the context without it suddenly becoming the whole thread. If people want to tell me I need to change his diet then fine, I’ve heard it now, several times over. when she knows I’ve asked her not to.

And maybe if he was a completely different size the comment would be viewed differently, I don’t know. But he is my child and I’m the one responsible for dealing with his health, not grandma making him conscious of his body every time he eats a biscuit.

I understand the desire not to have the MMN rabble redirect your thread to being about how to feed your DS rather than how to handle your DM.

I do think it’s relevant though, because you have sounded like you might have been in denial about DS’s weight and it does make a difference to how you should deal your mum.

Instead of telling your mum you need her to stop making these comments directly to DS, have you tried getting her onboard with what you are doing about it?

E.g. Discussing your concerns about his weight change, pointing out that he isn’t yet in problem place but you are trying to make sure he doesn’t get there without making it something he becomes self conscious about and develops into a lifetime of poor weight and eating habits. Talk to her about the damage clinicians have found making kids self conscious about weight has caused. Go over research if that tends to convince her, or try and find someone she might respect who has recorded a video or given an interview or something on the subject. Crucially, though, talk to her about what she can do that would be really helpful (e.g. not mentioning it, but buying them comics instead of sweets, having fruit or cheese and crackers in instead of biscuits, texting you if she notices something instead of saying it directly to DS, or whatever you think would work).

You’ve said you’ve talked to her, and this may be the way you went, in which case I would just keep up the pressure. But if you just told her what not to do and didn’t talk to her about your concerns and what you would like her to do to help, maybe knowing you’re taking it seriously will help? Because she isn’t wrong she’s just tackling it badly. If you’ve been speaking to her the way you’ve were posting here at the start, she might also be wondering if you’re just in denial and be thinking she has to tackle DS directly as she thinks you are not really facing up to to what’s happening.
