We have a generation that have been brought up to think that eating a burger and chips with their fingers is a "meal" due to McDonalds clever marketing ploys. When we were young, my brothers and I would have called that a snack, not that we had burgers back in the 50's and 60's.
So cutlery of any sort, held properly or not, may not play a part in many mealtimes. Playing with toys at the same time as eating is now normal for lots of children.
Also, many people don't have a dining table these days ! In the course of my work, I visit homes of the less wealthy every day and a growing amount of homes have nowhere to sit properly and eat meals. Quite how you teach children table manners when they are lolling around on a sofa eating food is beyond me. Its obvious that things like good table manners are no longer important to a growing sector of society. When I have asked people why they don't have a table and chairs, they look a bit bewildered !
