Should children know how to cook?

Yep !
And learn how to sew a button on.
And how to do the basics of cleaning.
And how to iron.
And how to hang wallpaper.
And how to fix your cistern.
And how to manage money.
And know their basic rights and responsibilities under the law.
And to know what it means to be a carer for somebody unable to help themselves.

To my mind these are basic life skills.

I'm glad my mother didn't teach me how to cook. She was a terrible cook!

Well children should maybe learn first

If they like to eat.

Depends a little on the age but in general, being kitchen-competent is a good thing, so that once they get out on their own they're not stuck eating fast food and takeout all the time.

They should start out with easy meals, it teaches independents, learning is part of growing up...

Darn Skippy they should, along with cleaning house, mowing the lawn, doing the laundry.
I think by the time.kids are almost out of grade school each would be doing their own dishes and laundry, hell with cooking and what not.
Not to become slaves for.the parents mind you, but to help them become self reliant, and more independent.
Plus if them selves jobless and fall on hard times, those skills could come in handy to.earn extra income in the future.

I think it’s great to introduce them to cooking at a young age such as doing small tasks in the kitchen that doesn’t require much effort or harm. It’ll probably help them become a bit more independent and I’m also sure be beneficial for them in a lot of positive ways. I would say what they could be doing in the kitchen should all depend on their age range though.

Not just cook... bake! With guidance ofcourse ☺️

Well, depends. My culinary skills are very basic. But I can feed myself if needed. I think that's what's important.

teens yes, like 13 and up.

yes otherwise they grow up not knowing how

Of course they should. Way too many people have no idea how to do much of anything for themselves anymore, and it's not leading anywhere good.

I let the niece help in the kitchen.

No one graduates from my house without knowing how to cook, clean, and do laundry.

Yes
They have to learn how to cook a basic meal

Yes.

Yes!

It's a valuable skill. I'd say so.
