What do you think of left-behind children?

My family has two nephews. I go home to accompany them every holiday. I have two small cotton-padded jackets myself. Every time I go back, I can clearly feel that my nephew envies his daughter. He always asks my aunt why you can accompany my sister and why my mother can't accompany us. At this time, I don't know how to answer him. I think left-behind children are really pitiful. Although grandparents may love them very much, what they need more is the love of their parents. Grandparents only know how to take care of their children's food and clothing, but they can't give them the feeling of love. If you can expect parents who can take their children to go out to work together, don't be away when your children need you most.
