Frequently asked questions
What should I write in a birthday card for my niece?
Lean into the aunt-and-uncle role — the spoiling, the secrets kept, the front-row pride. Add one line about who she's becoming; nieces keep the cards that notice their growth, not just their age.
What is a short birthday wish for a niece?
“Happy birthday to my wonderful niece — watching you grow up has been one of my life's quiet joys.” Warm, personal, and fits any card.
What do you get a niece for her birthday?
Something with a wow factor she wouldn't get from her parents: a bright bouquet with her name on the card, balloons delivered to the door, or an experience with you — aunt-and-uncle gifts are allowed to be the fun ones.
