This is following on from various discussions we have had on this topic at home.
I think that good table manners are modelled for children, and explained to them, at nearly every meal from the earliest age, by 4/5 (depending on their motor skills development) they should have mastered most basic table skills (eating with a knife and fork, eating with their mouths closed, not interrupting, waiting for others before starting/asking for second helpings, asking to get down etc).
What do you think?
