Grandparents Answer a Call
As a third generation native of Brownsville, Texas, Mildred Garza never pleased move away,. Even when her daughter and son asked her to move to San Antonio to help their children, she politely refused . Only after a year of friendly discussion did Ms Gaf finally say yes. That was four years ago. Today all three generations regard the move to a success,giving them a closer relationship than they would have had in separate cities.
No statistics show the number of grandparents like Garza who are moving closer to the children and grandchildren. Yet there is evidence suggesting that the trend is growing. Even President Obama’s mother-in-law, Marian Robinson, has agreed to leave Chicago and into the White House to help care for her granddaughters. According to a study grandparents com. 83 percent of the people said Mrs. Robinson ‘s decision will influence the grandparents in the American family. Two-thirds believe more families will follow the example of Obama’s family.
