I really don't understand why WDW doesn't have a policy on this issue

Teens no problem for me but little kids sitting at a table unaccompanied is not cool at any sit down but particularly for communal dining. We had an issue with this at Hoop this year. There was a large party maybe 18 people at Hoop. Adults and older kids sat at a table and then there was a table of 6 or 8 right next to us where the oldest kid was maybe 8 at the oldest including 2 kids in high chairs and 2 small toddlers. The parents were having a great time but did not assist their kids at all in ordering drinks or serving them. The food is all served family style and the CM ended up having to serve each child, cut up food, clean up lots of spills, etc plus so her other normal duties which was tough because the meal is paced just so. They also had a Birthday cake at the kids table that the CM also had to cut up and serve for the kids. The parents were far enough away that they didn't have to deal with anything but for the other smaller tables around the kids it was very annoying. The kids weren't even bad just at an age where they need some help and were a bit whiny. Legally it seems like WDW would be liable if a little one choked or got up and had a tray of food dropped on them etc if they are allowing children to sit by themselves.
