A grandparent’s teasing is a form of affection, and most grandsons give as good as they get.

How to Write Your Own Birthday Wish for a Grandson
Four parts, about four sentences
- Start with his name or the nickname only you use.
- Name one thing you noticed this year. He learned to ride without training wheels, made the team, or looked after his little sister.
- Share a memory or a plan. ‘I still laugh about the fish that got away’ or ‘the next campout is on me.’
- Sign it the way he says it. Grandma, Nana, Papa, Pop: the name he gave you is part of the gift.
The card carries more weight than it used to. In AARP’s Grandparents Today National Survey, more than half of grandparents had at least one grandchild living more than 200 miles away, and the share who had reached out to grandchildren by phone fell from 70% in 2011 to 46% in 2018 as group texts and video chats became more common. A handwritten line on his birthday is now the rare thing.
