Nope not rude st all
I send all meals with mine to both grandparents even though they both cook. It reduces their mental load for the day and I know exactly what he's eating. Nothing rude about it
I’d say it’s not rude but if she eats well on days she’s at home then there’s no harm in an unhealthy meal once in a while. My brother is 12 years younger than me and his dad earns a lot more than what my mum did with me and my sisters so they have quite a lot of nice foods. So when he sees some beige/basic foods he turns his nose up, Just saying you don’t want her being like that x
My daughter goes to her grandparents once a week, I send her with snacks, lunch and the milk for her nap time. They are watching her for free, so I think it would be rude not to provide everything they need 😅 She doesn’t always eat what I send with her but at least it’s something!
I send mine with food to my mother, she views it as it saves her a job
I’d do exactly the same. Don’t find it rude, I’d frame it as saving them a job, all they have to do is heat and serve.
