Birthday letter for your son

Dear Sam,

You are still little as I write this, and right now you are asleep down the hall with one sock on and your favorite stuffed bear tucked under your chin. Tomorrow is your birthday, and I wanted to write you a letter you can read when you are older.

I want you to know what you are like right now. You sing to yourself while you play. You ask why the sky is blue, and then why again, and again. You give your friend the bigger cookie when you think nobody is watching. You are curious, gentle and wonderfully loud.

As you grow, the world will try to tell you who to be. Some of that advice will be good, and some of it will not. When you are unsure, come back to this letter and remember the boy who sang to himself and shared his cookies. He was already someone worth being.

The letter

Dear {firstname},

You are still little as I write this, and right now you are asleep down the hall with one sock on and your favorite stuffed bear tucked under your chin. Tomorrow is your birthday, and I wanted to write you a letter you can read when you are older.

I want you to know what you are like right now. You sing to yourself while you play. You ask why the sky is blue, and then why again, and again. You give your friend the bigger cookie when you think nobody is watching. You are curious, gentle and wonderfully loud.

As you grow, the world will try to tell you who to be. Some of that advice will be good, and some of it will not. When you are unsure, come back to this letter and remember the boy who sang to himself and shared his cookies. He was already someone worth being.

I love you more than you can understand yet. Happy birthday, my sweet boy. I cannot wait to see who you become, and I will be cheering for you every step of the way.

All my love, now and always,

Make it personal

  1. 1

    Write for his age. Big, silly and simple for a little boy; short and not too sappy for a teenager; honest and grown-up for an adult son.

  2. 2

    Name one real thing. A trip you took, a habit he has, a moment you were proud of him. One specific line beats a page of general praise.

  3. 3

    Say the thing you rarely say. “I am proud of you” or “I love who you have become.” Sons of every age remember those words.
