Frequently asked questions
What should I write in a birthday card for my cousin?
Lean into shared history — childhood summers, family reunions, inside jokes. Cousin cards can be more playful than almost any other family card.
What is a short birthday wish for a cousin?
“Family forever, friends by choice — happy birthday!” or “Big love on your big day, cousin!” work for a text or a card.
What can I send a cousin who lives far away?
A same-day delivery in their city — flowers, a cake, or a treat box with a short note — turns a long-distance birthday text into an actual gift at their door.
