Psychologically, the importance of grandparents in the harmonious growth and development of children is undeniable. Even if they live away, you should do your best to take your child see his grandparents from time to time.
Children who are very close to their grandparents will learn many funny stories about the childhood of their parents and thus develop their sense of belonging to the family. In addition, the unconditional love of their grandparents helps them to be more confident and feel safe with other people than their parents.
Also, grandparents have much more free time to spend with the kids and more patience as well: they like playing with the kids, read them stories and emphasize with their genuine level of understanding life. Their experience in raising children can also be useful as long as it is needed and not imposed.
So if you have a harmonious family, visit each other when you have the opportunity. Schedule common vacations and encourage grandparents to come and visit. Make the most of the benefits of technology. Get the children to talk to their grandparents, communicate by email and social websites, send them photos etc.
Tell your kids stories about your childhood, about how prodigy you used to be and how your parents used to react. Children will be amused and feel much closer to their grandparents, even when they are away. Take time and go to a senior living community like http://www.erseniorliving.com/the-parks-retirement-community-odessa-texas.aspx and spend time talking with some of the grandparents, they will love it.
