Happy birthday, son: wishes for a grown son, by the kind of man he is

Once your son is grown, the wish that works best is short and specific. Name one thing you like about him as a grown man, recall a moment from his adult years and wish him one good thing for the year ahead. Leave out advice he didn't ask for. The lines below go from a mother or a father to a son of 18 or older, grouped by what he's like and how he likes to hear it.

An example: Lorraine drives forty minutes with a lemon cake on the passenger seat to see her son Danny on his 35th birthday. His new kitchen still has only one chair. She lights a single candle while he stands by the counter and opens her card. "Happy birthday, Danny. You call me when your car makes a strange noise, and you call when you've made a soup you're proud of. I like both calls. I like the man who makes them even more. Love, Mom." He reads it twice and laughs. "The soup was good, though," he says. Then he hugs her, and at six foot two he nearly lifts her off the floor.

Short birthday lines for a text or a card

These work on their own or as the first line of something longer.

• Happy birthday, son. I'm proud of the man you are.
• Happy birthday to my favorite person to argue about football with.
• To my son, who turned out better than any plan I had. Happy birthday.
• Happy birthday, Danny. Call me when you've had cake.

Birthday messages from Mom, and from Dad

A mother can say the tender thing straight out, and many grown sons like it. "Happy birthday, Danny. You're a grown man with a mortgage, and you're still my son. That part never changes." There's more on what's normal between the two of them in mother and son relationship. For lines that fit any other day, see mother and son quotes.

A father's message often works best short. "Happy birthday, son. Proud of you. Call me Sunday." If talk between you two tends to stall, father and son relationship looks at why, and a written card can say what a phone call skips. For the rest of the year, a dad can borrow from father and son quotes. For lines going the other way, from a son to his father, see happy birthday, Dad. His sister gets her own lines in birthday wishes for a daughter.

For the son who fixes things before you ask

He changes the porch light before you've finished the sentence and calls it nothing. He shows love by doing, so tell him in words that you see it.

• Happy birthday to the man who fixed my gate and wouldn't take a sandwich for it.
• You never say much, and you never miss a thing that needs doing. Happy birthday, son.
• I hope someone fixes something for you this year. Happy birthday.

For a longer card: "Danny, every time the porch light comes on I think of you up that ladder in the rain. You never make a fuss about helping, so today I'm making one for you. Happy birthday."

For the son who keeps the family laughing

He sends the family chat a joke at seven in the morning and does your voice better than you do. Answer in kind, then slip in one warm sentence.

• Happy birthday to the funniest man at every family dinner. Your dad says second funniest. He's wrong.
• Another year older, and still not funnier than your mother. Happy birthday. Love, Dad.

For a longer card: "Happy birthday, son. Your texts are the best part of my mornings, even the ones that arrive at six. The photo of the cat asleep in the salad bowl is still on my fridge."

For a son in another city or another country

When he lives far away, post the card a few days ahead and agree on a time to talk on the day.

• Happy birthday from home. We still set your place on Sundays.
• I worked out what time it is where you are, so I'm thinking of you over your breakfast.
• The miles are long and the calls are never long enough. Happy birthday, son.

For a longer card: "We're proud of the life you've built out there, even if seeing it takes a plane. The guest room is made up for March. Until then, happy birthday from both of us."

For the son who says little and means a lot

He calls when he has something to say, which isn't every week. He hates a fuss, so keep it short and true.

• Happy birthday, son. Two words from you have always meant more to me than a speech from anyone else.
• I know you don't like a fuss, so here's a small one. Happy birthday.
• Proud of you. Happy birthday.

A new husband or a new dad

The year he marries or becomes a father, he has a crowd of new people around him. A line from you that's only about him will stand out.

• Happy birthday to my son, the husband. I like who you are with Leah.
• Happy first birthday as a dad. You're doing better than you think. Sleep when you can.
• I'm proud of the father you're becoming, and I'm still proud of the son you've always been.

Wishes for his 18th, 21st, 30th and 40th

• 18th. "Happy 18th, son. The world gets one more good man today."
• 21st. "Happy 21st. You know your own mind now, and I like what's in it."
• 30th. "Happy 30th. You've built a life with your own two hands, and it looks good on you."
• 40th. "Happy 40th. These days you give me advice, and I take it."

If you're also planning the day itself, our 40th birthday ideas run from a loud party to a quiet weekend away.

A longer letter for a big birthday

For a 30th, a 40th or any year that feels important, a letter he can keep says more than a card. Here's one to borrow from.

Dear Danny,

You're 35 today, and I've been thinking about the man you've turned into. You show up. You helped your sister move twice in one year. You call your grandmother on Sundays, and when you make a promise, you keep it, even the small ones.

I don't say this often enough, so here it is in writing. I'm proud of how you treat people.

I hope this year brings you rest, a few good trips and plenty of reasons to laugh. There's always a seat at our table, and a slice of lemon cake with your name on it.

Love, Mom

Matching the wish to his type

Some sons keep every card in a drawer. Others read it in five seconds and would rather get a call. Typeza sees personality type as part of which kind he is. Seven of the 16 types:

• Ideator likes being surprised. Mention an idea of his you still think about, or ask what he's working out next.
• Vitalizer wants the warmth said out loud. Call early, sing badly and say "I love you" before you hang up.
• Inspector notices whether you follow through. A card that arrives on the right day tells him he matters.
• Commander speaks plainly and protects his own. Tell him straight out that you admire how he looks after the people around him.
• Strategist dislikes a fuss. One real question about his life, asked on a short call, beats a party.
• Guardian values honesty and kept promises. Skip the flattery, and keep any promise you make in the card.
• Craftsman shows care by doing and rarely hears thanks for it. Say plainly that you value him, and maybe give him one good tool he'd never buy himself.

Danny is a lot like the Craftsman, so a plain card and a lemon cake suit him.

See how you and your grown son fit together

A parent and a grown son can talk for hours about nothing and then get stuck the moment a decision comes up, and type is often part of why. You can find your own type on the free family compatibility test. Text your son the link from your result on his birthday. When he has answered, you both have your relationship type, on what flows easily between his type and yours and where one of you needs patience.

What should a father write to his adult son?

Short and true works best: one thing he's proud of, one memory from the past year and a plan to see each other soon.
