What should I write in a birthday card for my best friend’s son?

Start with his name, add one warm line, and finish with a wish for the year ahead. For example: “Happy birthday, [Name]! You make every family get-together better. Wishing you a year full of fun and good surprises.” Two to three sentences is plenty.

Should I send the message to the boy or to my friend?

For children under about ten, message the parent and ask them to pass it on, or send it to both. Boys in their teens and older usually appreciate a message sent to them directly.

How long should a birthday message for a boy be?

Match the length to his age. Little boys enjoy one or two lines. Teenagers prefer short and casual. Young men are happy to read a longer, heartfelt message if it feels genuine.

Is it okay to send funny birthday wishes to a teenager?

Yes, as long as the joke is light and friendly. Teasing about snacks, video games or growing taller is fine. Avoid jokes about looks, grades or friendships.

Can I post these wishes on social media?

Yes, they work well as captions or comments. If you’re posting a photo of a child, ask his parents first. Some families prefer to keep their children’s pictures private.
