To feel totally fed up cooking different meals.

[Sophisticatedsarcasm]

Basically at least 3 nights in a week I can cook up to 4 different meals.
My Nan has cealiac disease so she’s gluten free which requires no cross contamination. I know that’s not her fault it’s just really fraustrating. Then I have my sister who only eats about 10 things. My daughter eats most stuff give or take a few things and my son aswell.
My DP can’t eat much spicy because he has IBS.
Take tonight for instance.
Me and the DD are having chicken pasta, my DS hates pasta, never has liked it so he’s got Pie and mash and my sister has got pizza.
When I was younger it was eat what your given and I always thought I’d be the same. But I just can’t bare to see them hungry if I make them try and eat something they don’t like.
My DC are pretty open and always try new stuff. If they don’t like then fine they’ve tried it so I don’t mind, some stuff they thought would be disgusting they’ve really liked.
It’s just very exhausting especially after working, school run and housework then cooking 4 different meals not to mention the shit loads of washing up after 😭 anyone else feel the same.

But the nan is also fussy/set in her ways beyond the actual medical issue. So she will probably need to compromise a bit on likes and dislikes (while not compromising the GF stuff). Or cater for herself.

As with the sister, a public meal plan would help. The sister and the nan could let the OP know which family meals they were going to opt out of (and sort out their own dinner) and which they’re going to join in with. Then the OP/her partner can shop in the appropriate quantities and cook as advertised.

Is there any way you could cook extra of some of the meals your nan could have any freeze the spare portions so at least sometimes you only have to microwave a portion?

As for your sister, I think at her age you would be doing her a favour by encouraging her to try new foods- if she really only eats about 10 things she will find it awkward as she gets older and wants to be out with friends more. Perhaps this angle would also make her more willing to work with you on it. And/or maybe involve her in having to come up with things that she will eat that can be cooked along side what you are cooking for you and your children (ie using some of the same ingredients etc). Maybe the hassle of having to be involved in this will make her more willing to at least try to just eat what you're already cooking.

I really sympathise with you OP - this sounds like a massive and stressful undertaking!

Just my two cents on your troubles:

1. Would it be possible to do a large quantity of gf sausage casserole for Nan, with potato in? And then freeze? And maybe some sort of chicken&bacon casserole, same thing. Then you can just get a portion out of the freezer, defrost, add vegetables, voila.

1. I totally agree with other posters that your sister is young still and it is a great skill to be able to eat what you're given even if you don't like it.

It might be possible to make the meals more generally acceptable by offering a choice of starch eg. Potatoes or rice, pasta or (gf) bread (most pasta sauces work nicely as soupy stew things with bread and butter to soak up the juices...

1. Something like chips night (with chip shop chips, and home cooked eggs and beans) might be a good weekly tradition to be brought in, and should suit everyone's stomachs. It's also not very labour intensive!

1. You are in charge, so it is entirely appropriate for you to say "this is what there is, or you can make yourself some toast." (And in case you are worried about healthiness, beans on toast and an apple is an adequately balanced meal - even better if there's a bit of cheese on top).

If my mum isn’t working the evening she cooks my sister whatever and makes her eat it. However because she’s a little cow, the days my mum does work evening (5 nights a week) the minute my mum walks out the door she turns into a raving looney. So if I cook her something she won’t eat she just helps herself in the cupboards to random junk food. I do mention to my mum and some night my mum threatens her with no iPad or no football which is pretty much her life. But others she acts like a little brat and will not listen what so ever.
It pisses me off because when I was her age I cooked so my mum didn’t have to when she came home from work. I cooked, ironed did everything. she either is too lazy too or just not interested so feigns stupid. I dunno if it’s being the youngest but she gets away with half the crap me and my brother us3d to get in big trouble for.
She literally blames me for everything. If she has an argument with her mates it’s somehow my fault. My mum always tells her off and said she sick of her being a brat. I said so am I.... because I was never like that. I think it’s because my Nan has been a big influence and she quite bitter if she wants to be but let’s my sister away with everything.
