DH kicking off as I want to uninvite DMIL/DSIL from Christmas Day

You want to stop husbands family coming at Xmas and you think he should be ok with it? He should divorce you

Completely agree with @CheeseIsMyIdol. This bizarre desperation from posters to paint op as the villain of the piece whether
-not finding purposeful excessive farting hilarious
-making food and the family choosing what to eat and the quantities of it
-op not kowtowing to her dh as it’s -his faaamily and Christmas so all that matters is what they want or she’s a terrible person??

I think this is where I’d be. Lay the ground tiles and nip it in the bud. It’s gross and I wouldn’t want sit trying to enjoy Christmas afternoon surrounded by the smell of someone’s ‘boastful’ guffing

It's not a "health issue." FFS.

Gorging on Sunday roast and being flatulent afterward is not a medical issue. And even if it were, the outcome quite frankly is not something I would "tolerate" in my home if the offenders weren't making any effort to mitigate it. Either by eating more carefully/eating less, or by stepping away when they feel a "session" coming on.

Instead these nasty people made a show of it, egging one another on, competing and preening themselves about their emissions, in front of the children.

Low-class and inconsiderate to say the least, and none of that is even remotedly related to "health issues" the OP should be concerned with.

Oh, please. They were specifically asked if a Sunday roast dinner was "OK" when the husband invited them.

Furthermore, nothing compelled them to eat things that disagree with them, or eat them in the quantities OP suggests were consumed. They weren't on a deserted island where they needed to stuff in every possible calorie.

And regardless of the menu, there is ZERO excuse for the disgusting, proud, laughing display of / competition with their flatulence, in the living area, with the children watching. If their stomachs were upset they should have gone home, or at leeat stepped outside to emit their noxious fumes.

It’s completely standard to ask what dietary restrictions your guests have before cooking for them especially in this case when she knows they have stomach issues. That’s not pandering that’s normal hosting behaviour.

Because we were young kids and farting was absolutely hilarious to us then? 🤷🏼‍♀️

Why? If it’s such a non issue for so many here, why’s it so funny?

Absolutely op rather than —grim mannerless adults taking personal responsibility, absolutely pander to them.🤨I mean they and their twat of a son/brother are so considerate to you!

I’m sorry but this made me smile! It reminded me of my late aunt, she had terrible stomach issues and was always farting. We grew up with it so we’re used to it and it was always funny when we were kids.

This and your h is of course cooking isn’t he?

I would do a bit of research - or ask - what they should and shouldn't be eating - is it a particular condition?

See if you can adapt the diet to make their meal/day more comfortable for them.

Ask DH to tell MIL/SIL that you are trying to teach DC manners so a pardon me or excuse me after they fart would be greatly appreciated, even if it is funny

What a load of fuss about nothing.

Both you and your DH both sound awful tbh. You with your petty, intolerant attitude towards other people's health issues and your DH with his shitty attitude that he gets to dictate because he pays the mortgage.

Yes, your party SIL and MIL clearly lack a few social graces, but none of you are exactly covering yourselves in glory here.

Maybe just cancel Christmas altogether, it sounds utterly miserable all round.

@Christmasdayissue so who will do the cooking and house prep?

If (when) they start farting, TELL THEM “you’re disgusting, this is unacceptable behaviour and that under no circumstances will you ever host them again.

Let your goddawful H host his disgusting family then!

He pays more mortgage

you do the cooking/kids and god fucking knows what else. Stop!

Keep some air freshener by you at all times and spray them every time they do it. They sound awful.

Sorry you are going to have to endure them.

What about the "i get more say because I pay more of the mortgage" issue?

Knowing your shit does stink and therefore not forcing everyone around you to be trapped in a room with never ending waves of it for hours is more appropriate.

His mother and sister clearly think their shit doesn’t stink and it’s fine for everyone else to huff on the putrid fumes. Merry fucking Christmas indeed!

Yep.

Some pp seem to overlook that these disgusting actions were deliberate, competitive and forced. Because these nasty people thought that putting on such a display was hilarious and great entertainment for the kids.

Talk about limited, stunted people. I would not lift a finger to facilitate Christmas for them.

Why rude? OP isn’t obliged to provide Christmas for nasty, ill-mannered louts. They have homes and can make their own Christmas since they can’t behave in a civilized manner in otgers’ homes.

This x10000

I would truly sit and ponder at the level of jeering disrespect and nasty contempt toward me, that he and they are demonstrating.

Oh FFS. I'm 60-something and definitely more flatulent now than I was in earlier years. It does seem to get worse after large meals. However, I can manage perfectly well to control it when in the company of others because it would be really rude otherwise. I might nip to the loo occasionally, and I'd definitely be up for a walk outdoors, though!
