It isn’t going to be easy making changes to the food your children eat, and even the most careful, patient parents will probably find that the little ones will resist at some point and to some degree. The problem is that many of us were forced to eat in a healthy way as children: we learned the hard way. And the temptation to continue with these parental habits with our own children is strong. If you were made to sit at the table until you had cleaned your plate, you are not alone: most of the adult population have suffered this at some point ― at school if not at home. Forcing your children to eat, especially if they don’t like what is on the plate, is completely ______________. “Sit there until you finish” may be how we learned, and may also be the only way you feel able to achieve your goal, but think about it: the experience of eating a pile of unwanted cabbage until they feel sick is hardly going to make children jump for joy the next time it is served. This strict approach is very old-fashioned, and you may win the battle but you definitely won’t win the war. Delaying puddings used to be thought of as a good idea too, but guess what?That doesn’t work either. “No pudding until you have finished your main course” was the standard line when most parents of today were young and is still commonly used, but it only makes sweet things seem more desirable.
1. Does this line mean that delaying pudding will make children want it more? Why is it a bad way?
it only makes sweet things seem more desirable.
2. Is "standard line" a common way of saying "standard saying"?
