A good quote to share with a grandson is a citation from Victor Hugo: "There are fathers who do not love their children; there is no grandfather who does not adore his grandson." “Perfect love sometimes does not come until the first grandchild” is a Welsh proverb that grandparents can tell their grandsons.
“A grandfather is someone with silver in his hair and gold in his heart” and "Grandfathers are for loving and fixing things" are lovely quotes about the close relationship between grandparents and grandsons. Funny expressions include "Never have children, only grandchildren," "Grandmas are moms with lots of frosting," and "A grandmother is a babysitter who watches the kids instead of the television."
The quote "When grandparents enter the door, discipline flies out the window” indicates that grandparents are often more relaxed when disciplining their grandsons than they were with their own sons and daughters. “Grandparents are there to help the child get into mischief they haven’t thought of yet” is a quote that shows that some grandparents enjoy seeing kids behaving like kids and sharing a sense of camaraderie. The Italian proverb "If nothing is going well, call your grandmother” seems to indicate that grandmothers are often happy to use their experience to help grandchildren getting out of trouble.
