My charges also have to have good table manners... ive looked after them since they were 2 1/2 and 4, now 3 and nearly 5...
our rules are basically.... they sit at the table... on the chair PROPERLY.... feet under table, bottom in middle of chair etc and sit 'nicely'
they also have to eat 'nicely' using knife / fork / spoon as tools to eat appropriate foods...
at the moment i let them choose, but as long as they arnt using their fingers i dont really mind.
they also have to wait until everyone has finished before they get down.... and only when everyone has eaten the required amount of food nicely is pudding served....
Then its pudding time
They can eat their pudding 'nicely'
or it goes away...
if theyhavnt eaten enough of there main meal, then thats it.... no pudding
they can have there meal saved for if they are hungry later...
or else they can wait until next meal.
Genrally my charges have V good table manners and sit nicely and eat all / most of their main meal and pudding happily and 'nicely'
In fact only 3 times in 9 months have they gone without pudding, (and thats a total of them both!)
