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?

Paganpentacle · 28/09/2026 13:58

Depends.
Is he fat?
Is he on a proper eating plan?
She mentions second helpings and treats. That's hardly in his best interests.
Nobody wakes up one morning massively overweight... there's a steady creep upwards to the point where its very hard to reverse.
What are you doing about it exactly, other than pussy footing about and blaming your mum for speaking the obvious?

ScienceDragon · 28/09/2026 14:07

A) Based on details supplied by OP, her son is in a healthy weight range. Towards the top of that range, but still within.
B) Several posters have stated, quite correctly, that some children gain weight before a growth spurt (some do it the opposite way).
C) Fat-shaming, child or adult, achieves absolutely nothing. OP is quite right to shield her son from this.
D) Grandma is wrong in saying things directly to grandson. Irrelevant of culture, generation, intentions, etc.
E) OP's approach to head off potential weight issues is correct; encouraging physical activity, and making changes to current oral intake.

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.

Someone's got a "fat gob" on them and it's not granny!

Overwhelmedandtired · 28/09/2026 15:42

Sorry you are getting such a hard time.

With regards to your question, your mum was completely wrong to comment. She obviously doesn't understand the implications of making comments in those areas. If there is anything to address with your sons diet, approaching it gently and healthily is much more important than making accusations.

On his size, I had a quick look at the BMI calculator with the measurements you gave as I honestly had no idea if that was high for his height or not. It may be slightly over but there are a few really important things to consider. BMI is just a guide, and there are lots of things like bone density, muscle etc that all aren't taken into consideration, even for a child. Also, he may be due a growth spurt. Many children plump a little then shoot up. Add an inch to his height and he's back in the 'normal' range.

It sounds like you are focussing on healthy home cooked food, with some snacks and a good amount of exercise. That is the main thing. He is better having a second portion of dinner than lots of snacks too.

Good luck with your mum!

likelysuspect · 28/09/2026 08:03

I didnt comment on whether the example in the OP was done the right way or wrong way, Im simply responding to the blanket posts on here saying weight must NEVER be discussed with an 8 year old. That is plainly incorrect

‘Incorrect’ is subjective. I agree with you that weight and healthy eating in general is fine to talk about with children (I’d very much focus on health and strength etc though rather than weight and body size).

But I disagree that you need to talk to an 8-year old about their weight in particular, like it’s a problem. Or tell them they have to eat differently because they’ve put on weight. They don’t need to know that or feel responsible for it.

Change his diet from the adult level if necessary. He doesn’t need to know or worry about it.

Blondeshavemorefun · 28/09/2026 17:17

At 131 and 32kg so over 5s he is large yes for his age

as a comparison dd is 131cm and she’s 23kg so 3s 8

problem is if you don’t knuckle down now he will be much larger by year 6

he sounds similar in size to the largest in dd class and kids do notice it

hopefully with tweaks to his diet and snacks - it’s the snacks that often out the weight on

if has had a decent meal then shouldn’t need a snack but if they do then

if hungry have an apple or raw carrot not biscuits

Bababear987 · 28/09/2026 17:27

thepariscrimefiles · 28/09/2026 07:32

Surely you need to cut out eating out and doughnuts to be a good example to your kids? It's a bit hypocritical cutting out treats for your kids when having an unhealthy diet yourself.

Im slim and go to the gym dont eat unhealthily infront of them... but the main difference is OP seems to tbink its normal have crisps and biscuits about because thats what normal families do

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.

You’ve got it all wrong!

Of course, it’s good for an adult to apologise to a child if they’ve wronged them in some way. That’s assuming the adult makes the decision to do so.

But ‘disciplining ‘ a senior adult by forcing them to undertake a supervised , public retraction, while compelling them to ask the child to report any further misdemeanour to the parent?

NO!

What the connection is with telling a child they can’t go to the toilet, I can’t imagine, except they’re both abuses of power, one adult on child, the other adult child on parent.

MorganKitten · 28/09/2026 17:56

My aunt spent years calling me fat - I ended up with awful food issues and an eating disorder, I wasn’t fat just taller than her kids.

No, it's how it's carried out that matters. The grandmother just needs to take charge, telling the child and mother that she wants to talk to them - and that she reflected and has something to share. Then explain why what she did was wrong - so that the child hears there is nothing wrong with him - and the mother is there to support / hear the message - the mother only needs to be there because the grandmother has expressed reluctance to apologise / retract. So that's her fault.

It isn't embarrassing for the grandmother if she takes control and does it 'independently' - the child will be grateful for the supportive words from his grandmother. So sad some people can't look past the age difference as though that matters when it comes to manners and how we treat people.

This is all fine if DGM decides to do this for herself, as I said in my previous post.
What is very much not fine is being made to do this, or told to do this, especially by one's child.
The importance of the age difference is that the GM is being spoken about in terms of the need to be 'disciplined' BECAUSE she's older. It's not that I can't look past it. I'm simply pointing out the attitudes of SOME posters. I think GMs should be given the same respect as their adult children and grandchildren.
I'm not the one with the issue.

BagpipeBoss · 28/09/2026 21:41

I wouldn’t cut contact, but I’d be very clear that she must stop commenting on his weight. If she has concerns, she needs to speak to you, not him.

My son was always on the 99.9th centile and grew in cycles — weight first, height next. People didn’t always understand that, and he was bullied during his “chunky” phases. Those comments stick.

He’s now 17, 6ft 5, 19.5 stone, less than 10% body fat, and plays professional‑level rugby. His body was never the problem — other people’s comments were.

You’re right to protect your son. Family should be a safe place, not another source of criticism.

Can you quote where I ever said that? Are you confusing me with someone else?? I couldn't care less about anyone's age - that's my point! The grandmother doesn't need to be disciplined and I never said that - you made that up because you're so offended at the idea of a mother being allowed to defend her child against the child's grandparent.

It's always okay to tell others how to be respectful of your wishes when it comes to your children. Including your own parents who should know better anyway.

There are a number of posters talking about the GM as if she was a naughty, stubborn child, in need of correction. That is what my issue is.

EmeraldShamrock000 · 28/09/2026 21:58

I wouldn’t cut her off. An adult chat should be enough.

EmpressStorm · 28/09/2026 22:13

I notice two things, the defensiveness in your language but the words you use. For example you keep saying your husband isn’t massively over weight, he’s a bigger build, and you say your son isn’t huge or whatever, you minimise it

however your son is taller than the average 8 year old and he’s only technically overweight for his height, by 1lb. He’s actually on the cusp of healthy v over weight, for a child of his age and height

which makes me wonder Is your husband also actually a relatively healthy weight

your son isn’t fat. He’s 1lb into overweight. Your mother is out of line and I’d put that to her, she’s making a basically healthy weighr kid think they are fat. In addition he will likely have a growth spurt and it will then put him significantly into the healthy weight category.

im afraid I’m with you, I’d keep her gone.

Then add a post to the thread, replying to everyone. When you quote someone and reply to someone directly, you can't include (undisclosed) references to the general thread. That's not how 1-1 conversations work.

I haven't imagined anything. You just reiterated what caused you offence / distress. Okay - reply to the others about that then.

She has crossed the line too many times, others might be milder and overlooked.

I would be pissed off with her. We already leave in a world where we think we are far from perfect with the high standards we see online.

My DS is much bigger than his peers in height and weight, he’s off the scale for his age, noted as 99+ from birth. His Dad is 6’2 broad shoulders. DS gets down about it. I have explained that some Dads are big, listing the taller dads at football, others are smaller, you’ll all be adults soon.

Tell her never to feel so comfortable again or she’ll be out on her arse on the pavement.

People assume that they are big because they overate as children without control. In my experience those people were hungrier children anyway and would have felt starving, they’d have stole food, got it from neighbours. My child is never full. I refuse him food a lot, distract him, but he still eats more than his petite size 8 older sister.
My other child eats when hungry, she was always tiny.

i believe it is hormones or genetics.

Edited

Absolutely agree with this. Whilst of course it's important to eat as healthy as possible and to keep active and exercise at the end of the day some people are naturally (genetically) hungrier than others. It's a physiological glitch, not a moral failing.

I think it might be good to show your mum what is recommended in terms of talking to children about weight. She absolutely should not be undermining you as a parent. She has actually broken your trust which is a great shame as she has been so supportive. I wonder could you get her to read this or, read it together with her.

Acommonreader · 29/09/2026 18:50

I’d be very clear with her that this is a non negotiable and is unacceptable. Give her one more chance to change her ways.
My parents were like this about weight and started commenting to my dc- poking their tummies and saying ‘ some ones had enough sweets!’, naughty foods, have you earned that treat ? ……,
,Also commenting on other peoples bodies. I was calm but very clear that this would not happen again, that I would not discuss further and that I would not tolerate any negative weight talk. They have stopped fortunately.
