Dear Mary: how do I teach my grandchildren better table manners?

Q. We frequently have our very young grandchildren to visit. However it reduces us to teeth-grinding, stony silence when the parents allow their children to spend fleeting milliseconds at the table before galloping off around the room while we try to eat food which has taken time, effort and love to prepare. Trying to correct the children evokes defensive retaliation from their parents. We love having the family round. How can we tackle this diplomatically?

A. Say nothing. The grandparent role is to love unconditionally and effect corrective behaviour by more subtle means than criticism. Tackle this with a two-pronged attack. Introduce them to food like artichokes and mussels, in which the getting at it is all part of the enjoyment, and also takes time and effort for the eater. In addition source some well-behaved (and ‘cool’) children of the same age group or marginally older and invite them to lunch at the same time as your grandchildren.
