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?

YANBU - you can't trust her to stop making these disparaging remarks.

Let her cool her heels for a month - tell DS Granny has really angered you with her thoughtless remarks and she needs time to reflect on it.

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?

cartagenagina · 27/09/2026 15:23

YANBU. She needs to learn some boundaries.

CleverlyBeery · 27/09/2026 15:23

8 is far too young for this bullshit. She can express her concerns to you, not him.

If he's eating normal meals and is active then that's what you're aiming for anyway.

I'm sure she'll be back with "ooh mummy doesn't like me saying that! Oops!" comments. So yes cooling it for now is a good idea.

Passaggressfedup · 27/09/2026 15:24

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.

LVPLVT · 27/09/2026 15:24

You aren’t being unreasonable to treat this seriously and intervene, but I think it would be unreasonable to consider permanently stopping contact when she is otherwise a loving and doting grandma and both kids want to see her.

Perhaps you could meet her for a coffee and discuss this before she is around the kids again? It doesn’t really matter what she thinks about anyone’s eating habits as long as she doesn’t say it out loud.

IHaveQuestionsLotsOfQuestions · 27/09/2026 15:25

She shouldn't be making him feel insecure about himself, he's a child. She's out of order for putting that on him.

But to be honest, it's your job as a parent to look after his health and his weight is part of that. Where I do sympathise with her is it must be difficult to watch a child that young getting bigger and bigger and the parents not doing anything about it. You say he's not on any weight management plan, but if he's overweight - why not? He doesn't have to know about it. But it is your responsibility to make sure he's not eating loads of rubbish. It sounds like there's quite a lot of it in the house and within his access.

You mentioned her comment about your DH also being big - is weight and eating an issue generally in your household?

While there's no excuse for her being unkind about it, I can understand the frustration if nothing's being done to help him.

I don't think you should punish all the children for your mum clumsily drawing attention to a problem that is actually of your making and in your control to fix.

SnappyPenguin · 27/09/2026 15:25

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

Can you think of ways to teach kids about healthy eating that aren't the comments his grandma makes?

I can't think of any benefit of her comments.

Octavia64 · 27/09/2026 15:27

hard to comment on this without seeing your DS.

I’ve never known children be on a weight management plan or anything like that.

it could be that your DS is significantly overweight and cutting down on the biscuits and sweets would be a good call.

or it could be that he’s fine and your mum is making a storm in a teacup.

either way cutting contact completely for your whole family seems excessive. If she’s generally loving and supportive and involved, maybe check your DS’s bmi, and then if you really feel there is no need at all to move to a healthier diet just frame it as grandma worrying about food.

Halfblindbunny · 27/09/2026 15:27

Maybe she is a complete cow (although her other behavior doesn't seem that way) or maybe she is so concerned about his weight she has lost all sense of reason with how to approach it.

Stopping her seeing them is hurting everyone so not a great long term plan if it can be avoided.

I would go and talk to her without the kids or DH etc and have an honest and frank discussion. Explain you cannot have DS spoken to and about in the way she is as you are concerned it is affecting his mental well-being but also perhaps concede that little steps can be taken as a family to try to manage his weight.

I do get what you mean about healthy eating, and I’m not saying ds should just be allowed to eat whatever he wants and get bigger and bigger. I just don’t think an 8 year old needs to be told directly that he needs to watch his body. We do talk about healthy food and he’s active with football etc.

Also I never said dh is very overweight. I said that was the comment my mum made about him, that ds would “end up like his dad”. Dh is a bigger build but he isn’t very overweight or anything like that, which is part of why I thought the comment was so unnecessary. It wasn’t really about teaching him healthy eating, it was the way she said it and the fact I’d already asked her not to talk to him about his weight.

Your DM is wrong. Her comments aren’t harmless. It is totally unacceptable for her to be raising concerns about weight directly with your DS.
I will say however, an 8 year old shouldn’t need seconds or dessert, so you probably do need to look at portion sizes. I’d aim for no weight gain rather than weight loss.

JustGoogleIt15 · 27/09/2026 15:29

Your Mum is wrong. Totally wrong

However I don't know if you are minimising the size of DS because you don't know how to handle the fact that he's fat

Or if DS isn't fat

If DS is fat then it needs dealing with, carefully and sensitively even though he's 8

But not as your Mum deals with it. She definitely needs to be kept away for now

TrixieFatell · 27/09/2026 15:30

I don't think you are being unreasonable. Her comments (whether her concerns are justified or not) to your son are harmful and could cause significant damage to his self esteem and mental health. He may end up.with an eating disorder.

If she has concerns then she expresses them to you and you only. Shaming her grandson is toxic. I'd keep her away until she manages to control her mouth.

get a grip and handle it another way

TheIntricaciesOfHarpUpkeepAndMaintenance · 27/09/2026 15:34

YANBU. Even if she doesn’t agree with them, she needs to respect your boundaries re your children. It’s not difficult to just stop making comments about his weight and it’s very strange that she’s so unwilling to do that.

Is she generally quite unreasonable or does she usually respect your position on things and this is an anomaly?

Buynow · 27/09/2026 15:34

She was wrong to put the responsibility for his weight on the child but your post suggests he is overweight and it's your job to change that.
Don't hide from it, it won't go away on it's own he will just grow into an overweight teenager and adult. Childhood obesity is a serious problem often caused by parents who don't acknowedge that their child is overweight .

For goodness saje don't break a loving relationship with a grandparent over this.
Talk to her and tell her you are unhappy about her bringing it up in front of DS and she must never do it again. Reassure her that you acknowledge he is overweight and will tackle it without him knowing.

BTW I speak from experience. DS was a bit chubby at 8 and very chubby at 11. I naively thought he didn't notice and that pubity would resolve it. It turned out he did notice and was hugely self concious. He was late to puberty and I'm glad we didn't wait another four years to sort it out.

Jjjr · 27/09/2026 15:37

If I was a grandma I'd never say that to a grandchild, I'd address any concerns with parents and the parents that's my child.

Being a healthy weight is important. Diabetes and heart disease runs in my family. Healthy living is a good thing.

GrannyGoggles · 27/09/2026 15:40

Hmm, how ‘fat’ is your husband? And your grandchild?It’s a minefield. We don’t know if your mum is being horrid or expressing genuine, well based concerns

One thing I’ve learned is No Comment Ever on other people’s eating and weight, unless invited

If I’m in charge of food it’s veg heavy, no ultra processed. And I know that my dishing up of red meat, from farm reared cattle, (homegrown) fruit crumble pisses off next generation- cream, calories, meat

UbiquitousPistachio · 27/09/2026 15:41

I think it’s worth giving this another try, it seems a shame to destroy your children’s relationship with your mum when she seems a great presence in every other way.

You would need another chat to her and explain that there is zero tolerance in this subject. It doesn’t matter if she agrees with you or not - your kids, your rules.

At 8 you could probably start talking to DS in a more grown up way, explain that the older generation have some funny ideas about food and weight but you and he understand that healthy eating and activity are the most important thing.

On a practical level though, at this age his weight is entirely in your hands. You can control what he eats and how much, and you should be doing that discreetly if he is getting big.

chirrupybird · 27/09/2026 15:45

Say OK you can see them but no more comments about weight, tight trousers or what ds eats. I wouldn't ask her to apologise to him that just reminds him of what was said, just let it go as long as she never says things like that again. It is being cruel to your children not to see their GM that they love and may reinforce your DS's thoughts that he has done something wrong (by eating too much) so he can't see GM.

In some ways she may be right that he is putting on a bit too much weight but it is absolutely wrong to mention it in a disparaging way. If he is getting a bit heavy can you quietly reduce his portion sizes a bit? And make the availability of biscuits and snacks a bit less?

CleverlyBeery · 27/09/2026 15:45

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

Baffling.

JLou08 · 27/09/2026 15:46

Have you forgotten how cruel children can be? There's every chance he's already getting comments from children at school and if he isn't now he certainly will in a few years. If you really want to protect him from worries about his weight you need to feed him better. I think you already know this and are projecting your anger with yourself onto your mum.
Your mum has overstepped, but given everything else you've said about her it had been done with good intentions. Stopping her seeing the children is an overreaction and quite cruel.
