Can I ask how old your children are?
I have a 4 year old and 1 year old, and am trying work out the right level rules to enforce with my 4 year old. As said above by others, I focus on not eating in a disgusting way, not chucking things he doesn’t want off his plate, not taking too much and spitting it out etc. Using cutlery is still a work in progress but I do insist on a fork not fingers when it makes sense etc. Having done a lot of baby led weaning when he was little, where fingers are heavily encouraged, it’s hard to know when to row back from that but he uses cutlery fine at school.
Same with DD who is 1, she uses a mix of fingers, spoon and fork as she wishes, and we do also move bits of food off her plate onto the clean plastic place mat so it’s cooler and easy to grasp. Not good manners but works at home.
I don’t believe in making them wait till we all sit down, as they’re usually ravenous, and also then they’re more likely winding each other up if they don’t have food to distract them. Grandparents have always fed the children first too so why would I have stricter rules at home?
I’d like to work harder on ensuring polite conversation - DS does like it to revolve around him, but we tell him off if he’s being too overbearing.
I don’t make him stay at the table when finished but I insist that he clears his plate and carries it to the kitchen, as I want him to be a man who cleans up after himself!
Some times it’s hard to know when they’ve reached an age where they can handle the next set of rules so it could be that I need to step up a bit.
