How to write it

1. Match his age. A card written for a small boy is embarrassing to a nineteen-year-old.
2. Say what you rate about him. Boys and young men are praised specifically far less often than they should be.
3. Be the uncle, not the parent. Encouragement lands better from you; instruction does not.
4. Keep it short. Most nephews read three lines and put the card down. Make those three count.

FAQ

What do you write in a birthday card for your nephew?

Name something you genuinely rate about him alongside the wish. From an aunt or uncle that praise carries more weight than from a parent.

What do you write for a young nephew?

Keep it excitable and short — cake, presents, the party, and how much he has grown.

What do you write for an adult nephew?

Treat him as an adult: acknowledge what he has built and offer your company rather than advice.

Can it be funny?

Yes — teasing about parents, cooking, or being the favourite works well for most nephews.

What is a good short message?

“Happy birthday, mate! Have a great day.”

What about a milestone like 18 or 21?
