A birthday card for your son, whether he's six or thirty-six
Type his name, pick a picture and send him the link. It's free, and there's no account for either of you. Inside, a parent tells him they like the person he's turning into.
What the card says inside
The message is the same for every son card. Only the name changes, so there is nothing to sign up for and nothing to store.
Dear their name,
Some days I look at you and can't work out how you got this tall. I think I blinked. That's the only explanation I've got.
Here's what I want you to hear today. I love you, of course, but that part was always going to happen. What still surprises me is how much I like you. The way you see things. The way you make me laugh when I'm not expecting it. You did that all on your own.
You don't have to do anything else to make me proud. That's already settled. It was settled a long time ago.
So enjoy today. Stay up a bit later than you should. And whatever this year turns out to be, I'm here, and I'm not going anywhere.
Happy birthday, son.
What a son wants to hear on his birthday
Most birthday messages for sons lean on one of two things: how fast he grew up, or how proud you are of what he has done. Both are fine. The trouble with the second one is that it can sound like a scorecard, and sons of every age are quick to notice when praise is attached to results.
The line that works better is simpler. You like him. Not only love him, which he assumes, but enjoy his company and the way his mind works. That's the idea the letter on this page is built around, and it's why it doesn't mention grades, sports, jobs or anything he has to keep earning.
Anything of your own goes in the text alongside the link, and one specific moment from this year is worth more than a paragraph of general pride.
Reading it to a younger son
If he's too young to read the letter himself, hand him the phone and let him tap the envelope open. That part is his. Then read the letter out loud, slowly, and use his name the way you say it at home.
The letter was written to work when it's read aloud. The sentences are short, the joke about blinking is one small kids usually get, and nothing in it needs explaining. If he asks to hear it again, that's a good sign.
Sending it to a grown son
An adult son is more likely to read this alone, on his phone, between other things. Timing helps. If he lives in another time zone, send it when it's morning where he is, not when it's morning for you. A card that arrives at 3 a.m. gets read at 8 a.m. alongside a pile of work messages.
Keep the text that goes with the link short. Something like "Made you something, open it when you get a minute" works better than a long note, because the long note is already inside. A phone call later in the day still matters, and the card doesn't replace it.
If things between you are distant right now, this letter asks nothing of him and doesn't bring up the past. Send it, and try not to wait by the phone for a reply.
Kite, moon or pirate ship
There are three, and each suits a slightly different son.
The first is a quiet photo-style scene of a parent and a boy on a hillside at sunset, with a red kite and a cake on a picnic blanket. It works at any age and tends to suit grown sons best. The second is a bright cartoon astronaut holding a cake on the moon, which younger kids usually love. The third is a storybook painting of a boy on a pirate ship spotting a cake-shaped island, somewhere in between: playful, but not babyish.
What this card does and doesn't do
It's honest to say up front what you're getting. The letter is fixed. You choose the picture and type his name, and that's all you can change. There's no music, no scheduled sending and no way to see whether he opened it.
That's on purpose. Because the whole card lives in the link, nothing is saved on our side, there's no account to make, and it costs nothing. If the letter doesn't sound like you, a short note of your own alongside the link fixes that in one line.
Questions people ask
What should I write in my son's birthday card?
Tell him one thing you like about who he is, not only what he has done. Specific beats general: a habit of his, a moment from this year, something he said that stuck with you. If you're using this card, the letter covers the general part, so save the specific line for your own text.
Does this work for an adult son, or is it meant for kids?
Both. The letter doesn't mention school, work, age or anything that ties it to a stage of life. A grown son reads it as a parent being sincere for a minute, and a young one hears it as a parent who thinks he's great. For an older son, the hillside photo usually fits best.
My son can't read yet. Will he still enjoy it?
Yes, if you read it with him. Let him open the envelope himself, then read the letter aloud. It's short enough to hold a small child's attention, and the astronaut and pirate pictures are drawn with younger kids in mind.
Can the card come from both parents?
The letter is written in the first person, so it reads as coming from one parent. If you're sending it together, say so in your text, for example "From both of us." Some families send two cards with different pictures instead.
We haven't been close lately. Is a birthday card a good idea?
A short card is one of the gentlest ways to reach out, because it doesn't ask for a conversation. This letter makes no requests and doesn't refer to anything that happened. Send it without expecting a reply, and let him decide what to do with it.
Can I change the words in the letter?
No. Every son gets this same letter. What you pick is the scene and the name at the top. That's the trade that keeps it free: there's nothing to store, so there's no account and no cost. Add your own words in the text or email you send with the link.
Is it free, and do I need to sign up?
It's free, and there's no sign-up for you or for him. You get a link, he opens it in his phone or computer browser, and that's the whole thing. No app to install.
Will I know when he's opened it?
No. Nothing on the card reports back. If he's the kind of son who doesn't answer texts, a phone call that evening will tell you more than a read receipt would.
