oh, it's ok, we can share it reasonably
It was absent minded at best, or selfish at worse.
They both need a lesson in being mindful and sharing, but they both need autonomy and accountability. Bear with me... 🤔
If she has form for this, and is oblivious to who's is who's portion whilst eating (almost mindlessly) I would always get them to divvy up the takeaway/ treat portions and pop them onto completely separate plates /bowls.
As another PP said, one person divide stuff (pizza/takeaway/treats), and the other person choose - a tip as old as time! 🙌
My younger brother (2 years younger) was like this over chocolate and sweets which we only had at weekends. He was like a puppy eating treats, and would gorge on them absent mindlessly (whilst we watched TV), until he had eaten every last one, and was nearly sick. 🍫
Now we both had a big appetite and that was completely normal, but despite there being other food in the house, it was like he had no on/off switch for sweet treats whilst in front of the TV 🤷♀️
Mum would have us down water, so that we didn't mistake dehydration for hunger, and then split takeaways and treats in half every time we got them. It became habit forming to share equally and we got used to doing that.
Also eating at the table so we could register the food going in, instead of mindless eating in front of the TV helped massively. 💯
When he got a little older (late teens) he realised he just loved chocolate and would say to me, take whatever you like first and I will eat the rest. So I would never take more than half, and we both never argued over it, as it was a fair distribution, but he took the initiative to share and put me first. 😇
I don't think the issue is the food tbh.
She sounds like she's got a great healthy appetite and if she needs more food, then as my mum would always say if you are still hungry after your share, there is always a sandwich or something we can rustle up In the kitchen. 🥪
The issue sounds like she has form for not considering her sister and her feelings and she has a lack of accountability.
I would also (as a PP pointed out) make sure your youngest feels like she can speak up, and she doesn't have to have an adult intervene for her. 😔
I would keep repeating to your girls that takeaways and treats are a privilege and not a given. Maybe talk about karma? And hone down on being thoughtful and kind.
Your oldest needs to be accountable and feel some discomfort (not punishment) so I would let the youngest choose what takeaway and sides are / or the treats (and not let her be swayed by what sister wants) and also she gets first helpings and sister can wait her turn. 😉
On a side note, I feel for your eldest, as it must be hard being the oldest, as you are expected to set the standard, look after your sibling, have 100% responsibility, but 0% autonomy. 😔
It's tough, as she will have her own wants and preferences, away from her sister, but may feel pushed out, like she has to share everything, almost like a twin.
Do they ever order their own individual chosen meals, so they have their own preference?
Everyone thought me and my younger brother were twins as we did everything together. But we hated being treated as we were exactly the same... we were different. 🙄
My bro loved sweet treats and I loved savoury stuff.
He would get haribos whilst I prefered pringles. He preferred pizza, I preferred Chinese- you get the picture. 🍕
Do they always get the same stuff to share?
We did chores and got pocket money, thus could buy our own treats on a friday evening for movie night (pot noodles, crisps, sweets fizzy pop) and we had to stay within budget, but the choice was ours and the treats were ours alone. 🥰
Do they do any activities together with you, or do they get time with 1-to-1 you individually? 🤔
I would never punish a child where food is concerned, as it will just create terrible issues.
But I would have a consequence for inconsiderate behaviour, as well as trying to address WHY she is being so inconsiderate. 💯
Sorry for the longest post known to man. I hope you haven't got eye strain from reading my above thesis 😆 wishing you all the best. @SongsOfSongs
