If a child don't know thank giving,what should you do?

As a parent you have to set the examples when children are around then some friends gives you something then have to thanks them as the child is looking at the same time could motivate her to imitate your good behavior. Those scenes would always pop out in the mind of the children and would get used in thanking those who help them citing you as the role model.

Children are imitators. We adults should show good examples to young children by repeatedly doing the actions we want them to emulate. By looking at their parents the young minds can easily absorbed what they see. Teaching by example is the best way for us to impart good behavioral disciplines to children.

Well, I do agree that children learn from the parents, they see what the adults do, and they will follow. But sometimes, I saw the parents behave good, but not the children. I think it's because when the child did something inappropriate, and the adults didn't tell the child at the first place. Sometimes, the adults might think it's funny and this may encourage the child to do more of the inappropriate action. Or sometimes the adults thought the child is still young, and he will learn when he grows up, but not teaching him since he is young. When the child grows older, it has become the bad habit, and hardly change. Perhaps telling the children the reason of being grateful to others, why we should thank others. It's not only being polite by just saying "Thank You", but it's the attitude that we should teach them to be grateful. In Chinese, it's called "Gan En" (being grateful), I think we should really teach our children this.

zhouxi all the responders have given you good advice, and' all I can add is for you to do your best as there are always outside influences but you cannot shield your child from the rest of the world, and of course it is an imperfect world but you just go on being the leader in good behavior and your child will imitate you over and above anyone else. the parents are the idols of the little one and she or he will imitate you so do not fear.just know you are doing your best and your best is all anyone can do.
