Frequently asked questions
What should I write in a birthday card for my nephew?
Play the aunt-or-uncle card: the inside jokes, the games watched, the pride you don't have to hide. Add one sentence about the young man he's becoming — boys keep those lines longer than they admit.
What is a short birthday wish for a nephew?
“Happy birthday to my incredible nephew — watching you grow into this young man has been a front-row privilege.” One proud line that fits any age.
What do you get a nephew for his birthday?
Aunt-and-uncle gifts get to be the fun ones: tickets to a game, the gadget his parents vetoed, a balloon delivery that makes his friends jealous, or an afternoon doing his favourite thing with you.
