Besides manners and respect I think the child also needs to be taught to make adjustment, the importance of hard work, the value for money, the importance of time, to value their parents and siblings. These things will help a child to grow as a person in life.
i think the most important thing to teach kids is RESPECT!!
respect for self and for others.....only then will he/she be able to live and enjoy life and also be filled with manners and evry other ethic!!
