Father-in-law rude comments about autistic children in our family. AIBU?

I have posted about my father in law before and his attitude towards my autistic son.

Without repeating the previous thread, historically he has made comments about my 11 year old son - often in front of him - such as asking ‘what is wrong with him’ and whether or not he can ‘go to a normal school.’ For context, my son is high functioning, and thankfully he has often been absorbed in something else and hasn’t heard these comments. Recently, father in law told my son his special interest is for babies (it isn’t, it is anime), resulting in my son getting very upset and crying… he can be quite sensitive about being called babyish, he’s at that sort of age.

He also has a similar attitude towards my stepdaughter (his biological grandchild) and has called her ‘weird’ on multiple occasions and also asked me if ‘I think there is something wrong with her.’ Approximately a month ago, he made these comments to me again and I told him to stop, said there isn’t anything wrong with her, and that she is autistic and has ADHD. I’m not sure whether my stepdaughter has heard these comments herself, but she’s decided she doesn’t like him and also says he is mean to my son.

I also had an incident with him recently, my son had an accident and broke his arm, which father in law then asked me ‘whether he had done that to himself as autistic people are always smashing their heads on things’. I gave him very short shrift and asked him when he had ever witnessed that behaviour from my son, and also told him that’s an autistic stereotype that he shouldn’t be making.

He also constantly asks me if my toddler is anything like my son was at that age, which I think is him asking whether I think my toddler is autistic or show signs of autism.

This all leads up to the latest incident. On Friday we had my father and mother in law babysitting for an evening, I said to my husband at the time that I didn’t feel comfortable with this because of his prior comments, but it was a special occasion for another family member and we didn’t have any other options. My husband went to visit his dad today, and his dad explained that my son had been rude to him, so he then ignored him and didn’t talk to him for an hour, and when my son asked why he wasn’t speaking to him, he replied that it was because he was very rude. To be clear, sometimes my son can seem rude or make inappropriate jokes or comments, but he is never meaning to be intentionally rude. It’s part of his autism and when it’s explained his comments could be seen as rude, my son is absolutely mortified and very apologetic. He’s certainly not a rude or mean child. My father in law then followed this up by saying to my husband that there is ‘something seriously wrong with my son and he needs serious help.’

I am fuming and feel this goes beyond just ignorance, particularly as I have pointed out his ignorance on two occasions involving two different children in our household. My husband doesn’t want to say anything himself as my father in law is the type to fall out and not speak for months - there have been instances where husband and his dad haven’t spoken in over a year because father in law struggles with any sort of criticism.

It’s the first time he’s ever babysat and will be the last. I feel sad that my son was ignored for an hour not understanding what he’d done wrong.

He sounds like a total shithead. Does your MIL make any attempts to correct him / challenge him?

No, she’s extremely passive.

Is your son his biological grandson?

JackieQueen · 16/08/2026 18:36

What a nasty piece of work, ignoring you all must be a bonus! And more peaceful.

Fluffyholeysocks · 16/08/2026 18:37

Have you pointed out to FIL 'that there is something seriously wrong with him and he needs serious help?'

Gardenisablooming · 16/08/2026 18:39

He'd stop speaking to you for months ?thats a fucking win surely ?

According to father in law, he was rude because father in law asked him about something, and he replied that he didn’t want to talk about that anymore (it’s a topic he’s been asked about a lot recently). So father in law then ignored him for an hour until my son asked why he was being ignored.

No, but he’s made similar comments about his biological granddaughter so it seems anyone neurodiverse is fair game.

There’s something very off with FIL’s social functioning. Some readers may be ahead of me now…

PivotPivotmakingmargaritas · 16/08/2026 18:41

“is the type to fall out and not speak for months - ”

That sounds like a win… you need to protect your children and have nothing to do with him - he’s an ignorant bully. Age is no excuse as the days of calling kids weird is long long gone.

I was asking as Autism is hereditary. As your step-daughter has it, maybe FIL does too, and therefore his condition affects his filter so he ‘says what he sees’ etc…

nutbrownhare15 · 16/08/2026 18:43

Your husband also sounds extremely passive. What did he say to these comments or did he just pass them on to you. I'd be cutting off contact with your son as it sounds like there is no need for them to be in touch and your DH will have to enable contact with SD if he wishes to although I'd be explaining to DH that FIL's attitude will be extremely harmful to her as she grows up. Fil doesn't speak to you for months when upset? Sounds like a bonus.

DelphiniumBlue · 16/08/2026 18:43

I think there need to be some frank and ongoing discussions about what autism is and how it can affect people, and your child specifically.
My guess is that FiL isn’t meaning to be unkind, but isn’t educated on autism. There is so much more knowledge and information about autism which has become more publicly available in recent years, and it might be helpful if you could explain some of the issues to him, but also point him in the direction of where he can find out more, maybe the National Autistic Society or similar. He doesn’t sound uncaring, but ignorant.
Whether you’ll want to have him babysitting in the meantime, or whether he’ll take you up on your offer to educate him, is another question.

DaisyChain505 · 16/08/2026 18:47

A) Why aren’t you shutting down his comments immediately every time they’re said.

B) Why isn’t your husband shutting down comments immediately every time they’re said or confronting him when he’s told by you what has happened.

C) Why are you letting this ignorant, small minded man have 1 on 1 time with your son when he clearly has an issue with him. No occasion in the world is worth doing that.

Stop letting him babysit, stop visiting and tell your husband to sort his fucking Dad out.

Exactly. Discuss this with him-it might even help him, and then help him have a better relationship with your kids, OP.
Don't know how old he is, but even in the 90s, a lot of children with autism didn't go to mainstream schools (and a lot of people who were at school then will have been diagnosed recently, but when his kids were young, there would not have been many kids at the school diagnosed with AuDHD, so maybe he genuinely thought a diagnosis meant they can't go to mainstream).

I thought he’d shut up after the two conversations I’d had with him about autism recently, but clearly not.

I’m not sure how much I’m expected to educate him on autism and ADHD, given I’ve already had these two incidents.

It’s the fact he keeps using language of ‘something wrong with them’ in respect of the two neurodiverse children in our household, despite having this pointed out to him that it’s not ok.

But you should NEVER have left your child in the care of this man. No social occasion is worth that.

Topseyt123 · 16/08/2026 18:55

FIL not speaking to you for months sounds like the ideal scenario to me so I wouldn't care at all about upsetting him.

Don't let him babysit again. Nor MIL if she is so passive. Cut contact between him and your DS. Also with your stepdaughter too if you are able to.

I see it suggested that your FIL might be just ignorant rather than unkind. I agree that he sounds ignorant, but I also think he is very, very unkind and not the sort of person you want to have much involvement in your child's life.

WhatNoRaisins · 16/08/2026 18:56

Is there an element of doing the same thing again and again whilst expecting different results with this man?

MyAzureZebra · 16/08/2026 18:56

Pay for a babysitter? Is your FIL autistic as well?

AFigureWalks · 16/08/2026 18:57

I would have gone absolutely nuclear with the horrible bastard. Fall out with the fucker, tell him what a shitty, terrible person he is.
He is a bad person to have around you and your children.

His behaviour doesn’t call for a polite chat about autism. It calls for you to be direct and stern and to shut him down in the moment.

“Just because you don’t understand something or choose not to educate yourself on a subject doesn’t mean you have an excuse to be rude to my son. Do not use that kind of language or speak about him like that.”
