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?

Was she obsessed with your weight when you were growing up? I have a mother who equates thinness with goodness. She was obsessed with my weight as a child and has made incredibly crass comments to all her granddaughters at one point or another. I remember her telling my then 8 year old niece that she was fat and that she was telling her this because no one else would. My brother went spare at her but she would not back down. To this day she constantly mentions people’s weight and tells us how she’s restricted her diet - I just ask her is she looking for a round of applause which normally shuts her up.

People on this thread are saying that an 8-year-old shouldn't gain weight.

Baffling.

There's gaining weight and gaining too much weight, we do not know if he is gaining in line with expectations for his age and height or if he is actually getting too heavy.

Scottishskifun · 27/09/2026 15:49

Your compromise of getting her to apologise and not do it again is a sensible one. She will be learning that she has crossed a boundary and needs to accept that it's as a result of her actions.

However there is also a certain level of things you can do as a household and that's not free reign access to biscuits and sweets. Healthy meals will not counteract that and children do need to learn moderation. A child will always choose sugar studies have shown that it has a similar dopamine hit in the brain as certain drugs.
Giving complete free reign to it will not teach healthy eating it will get him hooked on the hit from sugar.

You don't need to explain that's because of his grandma though it's a simple as a household we are going to improve diet. Free access to fruit, sweets and biscuits limited in moderation. We go for max 2 biscuits a day and sweets only for after sports.

No, people on this thread are saying and 8 year old shouldn't be overweight.

Hankunamatata · 27/09/2026 15:50

Difficult. Id be fuming about weight comments. They should be addressed to you.
No I wouldnt stop her seeing them if kids want to see her.
Speak to her infront if ds if she makes a comment to him and correct her infront of ds.
Keep communication open with ds. Focus on healthy bodies, eating fruit and veg and moving bodies in a fun way each day. If he isnt in a football club it could be great way to increase movement as most train at least twice a week and weekend matches.

As a seperate issue. Your dc doesnt need seconds or extra biscuits or adult portions or dessert every day. You have said he is already fatter than kids in his class and put in more weight. Time to get him doing a sport everyday and swapping seconds for fruit.

heedmywords · 27/09/2026 15:51

I was an overweight child, I wish I had more people intervene to stop me over eating. I didn’t have an off switch and my mother who didn’t have a weight issue kept a well stocked biscuit tin and provided huge portions of chips etc!

If he is over weight sadly he won’t just be hearing comments from your mum, school children will quite likely eventually make some too. He will also start to compare himself to his peers more as he gets older. So his worry about his weight may not be purely from your mother’s comments. Your mum isn’t actually calling him fat to his face just saying he needs to be careful and whilst that isn’t going to help him and is the wrong approach it is most likely coming from a place of care and concern.
Also it is true that boys get fat if they eat too much rubbish- no point in pretending it’s not true and there are no consequences to what we eat. Being mindful about what you eat isn’t necessarily a bad thing.

Tell her to cut it out and give her another chance.
But look at whether you need to be doing more to change habits and portion size if he is carrying extra. Maybe she is just anxious about unhealthy habits and if she sees you have it under control she’ll stop worrying/ trying to intervene.

TurtleMcTurtle · 27/09/2026 15:52

He’s 8. What he’s eating is entirely decided by his parents at this stage, it’s not like he pops out at school lunch and buys a take away is it?

Why don’t you write down EVERYTHING your son eats in a week, add up all the calories, look at the sugar content etc and show your mum that it’s easily between the 1,400-1,600 cal daily intake that’s recommended for 8 yr old boys.

Then, once you’ve shown her the food diary and that the calories consumed/sugar intake is in the healthy range, she should have her answers and be quiet about the situation.

If, on the other hand, you realise he’s consuming much more than he should, it could benefit his health to address that and make healthy changes.

Bromatic · 27/09/2026 15:52

She shouldn’t speak to your son directly as she has but you shouldn’t break their relationship over it. It’s being overweight that causes the issues at school and elsewhere that create poor self image. Potentially she is doing you a favour by making sure the issue isn’t left. Most 8 year olds aren’t over weight - it’s not clear yours is but actually your mum’s behaviour needs to be seen in the context of the issue. If he is over weight then that’s is the big issue and things you don’t need include sweets and crisps in the house and seconds at tea. Portion size matters the most and using veg to bulk out the plate. It’s a good time for evaluations all round. Her for the language she uses and hours for the food you are feeding. What works for one kid doesn’t work for all. One of mine puts weight on super easily - the others don’t. He got fatter and I changed his food and we took up running. Made a big difference.

alittlepieceofme · 27/09/2026 15:54

YANBU - you’ve already asked her to stop and she hasn’t!!
she’ll do it again as she thinks she knows best!

MangoMusique · 27/09/2026 15:54

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.

CombatBarbie · 27/09/2026 15:55

Well she obviously shouldnt be saying those things, but as pps have said its impossible to say whether its bitchy or clumsy concern.

What height/weight is he, is he in age 8/9 clothes or age 12/13.

Mumofoneandone · 27/09/2026 15:56

Your mum clearly needs to be careful about what she says to her grandson about his weight. However, he is clearly overweight, you don't sound like you are listening to her or doing anything about it...so maybe it's her last resort to talk to your son about it to try and help him longer term.
So, yes you are unkind in stopping her seeing her grandchildren.
Perhaps do a food diary for what your DS is eating/drinking every day. It's often the type of food rather than quantities that's the issue. Get rid of sweets, treats, biscuits from the house. Ensure UPF is minimal and occasional. It often doesn't take much to loose the weight. It will be better for him in the long run.
My 8 year old DS has a huge appetite, but a pretty healthy one ( ie only home made cakes - no standard sugar as he's allergic to it) no UPF and is pretty active but is slim.

BobbleBear · 27/09/2026 15:58

Hmm, it sounds like you might be in denial about his weight especially as you accept that your DH ‘has a bigger build’ whatever that means.

Lots of kids get chubby before they have a growth spurt so it could be that, but it’s usually pretty obvious if that’s the case or they are actually over eating.

You presumably know the difference?

Your mum clearly loves your kids but she’s probably worried that all the second helpings and extra sweet based ‘treats’ you’ve admitted he has, aren’t setting him up for healthy eating.

I’m probably near your mums age and we only ate normal sized food portions as kids and sweets were only bought and eaten on Saturdays with our limited pocket money. Fat kids got picked on at school because they stood out from the norm.

I do see a lot of plus size kids being given crisps & chocolate to keep them compliant and I think it’s setting them up for a lifetime of being overweight.

I think your mum cares a lot and is trying to stop that happening. Maybe you need to have an honest conversations with your mum and maybe consider whether you are guilty of using food and sweets as rewards?

thepariscrimefiles · 27/09/2026 15:59

Your mum was very rude about your husband as well, using 'you'll end up like your dad' as an insult about your son's weight.

She could apologise and says that she won't make comments about his weight again but she has doubled down and made you the villain.

I would never make unkind comments about my grandchildren's appearance and certainly not in front of other people.

MustTryHarderAndHarder · 27/09/2026 16:00

Why is he having dessert? He should be having fruit after his dinner.

If your husband is also overweight, then you need to look at all your diets.

You can't just ignore you child getting overweight because he is 8. Once he puts the weight on, it will be very difficult to get it off.

I would let your kids see your mum as long as she stops talking to him about hsi weight, but you need to do something about all your diets.

concertinacornflake · 27/09/2026 16:01

It wouldn't be unreasonable to ask to talk to her seriously and tell her that she either stops making any comments about weight and diet, or stops seeing the kids.

Tell her she can discuss and weight or diet issues with you in private.

I'd also ask her whether she has a reason for being unable to stop talking about this.

Halfblindbunny · 27/09/2026 16:03

OP I mean this kindly '!normal meals with fruit and veg' means nothing if we don't know what you consider normal and what the portion size is.

Also football twice a week and playing outside with friends isn't an objective measure of how much actual exercise he is getting. Some kids manage to go to after school football or even football club training and not move nearly as much as you would imagine.

You say in your original post he isn't obese but there is a huge range between healthy weight and obese which would also be concerning for an 8 year old.

MustTryHarderAndHarder · 27/09/2026 16:04

You seem to be in denial. Why do you have crisps and biscuits in the house if your son and husband are overweight.

You say that your husband isn't VERY overweight, but he shouldn't be overweight at all.

You need to look at all your diets and get help.

MangoMusique · 27/09/2026 16:04

I think some of you are assuming he is much bigger than he actually is. He isn’t in age 12/13 clothes, he’s in age 8-9 and sometimes 9-10 depending on the shop. I’m not going to put his exact height and weight on here but he’s not massively overweight. He has just got a bit bigger recently and is more conscious of it.

And I’m not going to start counting every calorie and weighing everything he eats. He’s 8. He has breakfast, lunch, dinner, fruit, vegetables, snacks and treats. He has dessert sometimes because we’re a normal family and I don’t think having fruit after dinner is some rule we have to follow every single day. He’s also active and plays football twice a week.

Also again, I never said dh is very overweight. I said that was my mums comment about him. He is a bigger build but he isn’t massively overweight and weight/eating isn’t a big issue in our house.

I’m not ignoring ds’s health, I just don’t think making him conscious of his weight is the answer. I have already asked mum not to talk about it with him and she keeps doing it anyway. That is what I’m actually upset about. If I thought there was a genuine health problem I would deal with it, I’m not refusing to look after my child.

As above PP said .A 3 week break ,and tell her she cant see them and make any weight type comments!If shes a good Nan otherwise ,hopefully she will wind it up.

JustGoogleIt15 · 27/09/2026 16:08

OK. So taking on board what you've said about DH and DSs weights..... not only is your Mum wrong to talk about "fat" to an 8 year old, she's also seeing things which aren't there. Which is very dangerous

I would go NC

Screamingabdabz · 27/09/2026 16:08

What a shame you’d block an otherwise loving and fulfilling relationship for this one issue.

Nobody is perfect. Just let her know how strongly you feel about her mentioning his weight and forgive her.

If he feels he’s responsible for a big family fall out (he isn’t but kids will pick these things up) he’ll be holding onto that too.

Draw a line under it and move on.

Summer26woohoo · 27/09/2026 16:08

PepsiBook · 27/09/2026 15:22

I think it depends on how big exactly your son is. There are many over weight kids at school and it's cruel to just let them carry on getting bigger and bigger, without stepping in.
You've just said that dad is large, if your son sees him and copies his habits then he told will also be very large. Most overweight parents have overweight kids, sadly.
If they're not told about healthy eating, how will they learn?

Absolutely irrelevent.

He could be the size of a baby elephant. The mum is absolutely out of order with her digs and comments to the child.

If she was genuinely concerned she can raise it, privately, with the parents. She could limit portions at her own house, she could only bring out healthy food for the grandkids, she could drag them on three hour dog walks because she needs to get fit. She could do all of this without opening her mouth to the child.

The fact that she continues to talk to the child about portions, size, waistbands, possibly getting fat - DESPITE already being asked not to several times - is the problem. She thinks the parents are wrong, she thinks she has a voice that needs to be heard by the child, she thinks she has the right to step on every boundary and request by the parents and clearly intends to keep doing it.

She is bang out of order and I would be RAGING. And absolutely I would have a couple of weeks of space with any future visits being closely supervised by me or dad.

AlphaApple · 27/09/2026 16:09

Your mum is totally out of order.

Kids can fill out ahead of a growth spurt. If this is a reasonably recent change and there’s been no other changes to his diet and lifestyle then that could be the explanation.

However, you sound defensive. There is a middle line between “putting an eight year old on a diet / calorie counting” and having a laissez-faire attitude towards nutrition. If you want advice on how you and your H are feeding yourselves and your family you could start a new thread and post a typical week’s food.

JACT · 27/09/2026 16:09

You don’t need to ‘make him conscious of his weight’ to stop further excessive weight gain and allow him to grow into his weight - this is often recommended for growing children, that they don’t lose weight, but just don’t gain any for a while as they grow taller so naturally thin out.
He is obviously consuming more calories than he needs if he has recently got overweight, so a reduction in what he currently eats is all that’s needed, smaller portions of his meals (or adding more veg while reducing carb heavy foods) and gradually reducing snacks can easily be done without any mention of his weight to him.
