How to Write a Birthday Message for Your Cousin

A birthday card for your cousin only needs three or four sentences. These steps make it easy to write one.

1. Start with a happy birthday and their name. A family nickname works too, especially one that only the cousins use.
2. Mention a shared memory. Holidays at your grandparents' house, family reunions and summer visits are good places to start.
3. Say what they mean to you. One honest line about why you are glad they are in your family is enough.
4. Close with a wish or a plan. "Let's get together soon" or "I hope this is your best year yet" keeps the card warm.

Example: "Happy birthday, Jess! I still think about those summers at the lake with Grandma and all the hours we spent on the dock. I'm so glad we are still close. Let's plan a visit this spring. Love, Katie"
