47 Big Brother and Big Sister Messages That Write to the Child, Not the Baby

Write to the child, and do not hand them a job

Three habits spoil most big brother and big sister cards. The first is the job offer: you will be such a help, you can fetch the nappies, you are in charge of teaching her everything. A four-year-old did not apply for any of that, and a ten-year-old can hear the workload hiding inside the compliment. The second is the age push, the you are so grown up now line, usually delivered in the same week that child has been told to be quieter, wait longer and need less. The third is compulsory delight. Telling a child they must be thrilled leaves no room for the child who is mostly worried, and that child then learns to do the worrying quietly, which is the worst outcome available. Write to the child as a person whose life changed, name one thing that has not changed, and let the feelings arrive at their own speed.

I got this wrong in October 2022, with a card I sent to my cousin's daughter Lowri in Stirling. Lowri was four, her brother had been home for five days, and I wrote a bright line inside her parents' card saying she would be a wonderful help with the baby. Her mother rang me the following week, not cross, just reporting. Lowri had asked whether helping was why the baby had come to their house, and whether the baby would leave if she stopped helping. Four-year-olds take a card literally. They do not have a setting for decorative wording. The card I sent next went to Lowri alone, in an envelope with her name spelled out in full on the front, and it said only that her brother was small, that her bedroom door still closed, and that the red cup was still hers. She carried that one around the house for two days, her mother said, in the pocket of a dressing gown that had no other use for a pocket. Address the envelope to the child. Keep the duties out of it.

One practical rule decides which bank below you need. Age matters more than gender here, and honesty matters more than either. A toddler's card will be read aloud by an adult, probably twice, so it has to sound right in an adult voice and be short enough to survive a second reading. A teenager's card will be read alone and kept or binned on its merits. And if you know the child is struggling, do not borrow a line from the cheerful banks and hope it lifts them. Use the hard-week bank. A child can tell when a card is performing optimism at them.

For a new big brother

Boys get handed the protector script early, often before they have met the baby. The lines below keep the pride and drop the guard duty. If you name the baby, use the name the parents use, including a shortened form if that is already the house version, because a big brother hears his sibling's name in a card as the first proof that this new person is real and staying.

• Congratulations on becoming a big brother. Your sister arrived on Thursday, she is smaller than your rucksack, and she has no idea yet how lucky the draw was.
• To the new big brother: nobody in this house got a vote, and you got a sister anyway. For what it is worth, she stopped crying the first time she heard your voice.
• Big brother, as of this week. The baby will learn your name early, because everyone says it while they are looking for their keys, their phone and you.
• You are a big brother now. That means a person exists who will follow you from room to room for about six years. Start practising your patient face.
• Congratulations. Your brother is here, he sleeps through your drumming, and the adults have agreed that counts as compatibility in this family.
• To a brand new big brother: you do not have to share the good biscuits yet. Some things stay yours, and the biscuit tin ruling stands until Easter.
• Your sister has arrived, and the house has a new expert in it. You are now the person who knows where everything in this house is kept, including the things the adults have lost.
• Big brother news is the best news in this card. The baby is lovely, she is also mostly asleep, and you are the interesting development in the family this month.

For a new big sister

The sister version of the same trap is the little mother script: so caring, so natural, born to help. Some girls love being handed the baby. Others have been holding other people's babies at family events since they were six and are quietly done with it. These lines congratulate the girl herself, on her new standing in the family, and leave her free to decide what kind of sister she turns out to be once she has had a few weeks to consider it.

• Congratulations on becoming a big sister. Your brother arrived on Saturday, he has your father's eyebrows, and he will be told about you before he is told about anyone else.
• To the new big sister: the baby is not a doll, whatever the visitors keep saying. She is a small, loud housemate, and you are the first person she met who was her own size once.
• Big sister, in writing, because you asked if it would be written down anywhere. It is now. Your sister is here, and your name is in her card before anyone else's.
• You are a big sister now. When the baby is old enough to want things, she will want your things first. This card is the official record that they were yours.
• Congratulations. Your brother slept through his first meeting with you, which the midwife called a good sign and which you have chosen to accept, this once.
• To a new big sister: you can be the person who reads to the baby, or the person who refuses on principle. Both are respected posts in this house.
• Your sister has arrived, small and cross and completely unaware that she has landed a big sister who has been rehearsing introductions since August.
• Big sister is a title you will hear a lot this month. This one comes with no duties attached. The rest of the card is just pleased for you.

For toddlers and under-fives: cards that get read aloud

Write these on the card itself, keep them under three short sentences per line, and expect each one to be read out loud at bedtime by a tired adult who will skip anything that sounds like a greeting-card motto. Concrete beats abstract at this age every time: a foot they can touch, a cup that is still theirs, a star on the envelope. If the child cannot read yet, the envelope matters as much as the text. Put their name on it, in their favourite colour if you know it, and let them open it themselves, slowly, with the tearing done badly.

• You are a big brother. This card is yours. The baby is little, you are big, and the cake in the kitchen has your name on it too.
• For a big sister: the baby says thank you for the song. She cannot talk yet. We could tell.
• Your baby brother is here. You can look, you can touch his foot, and you can go back to your trains whenever you want.
• To the big sister: this is your card, not the baby's card. Yours has a star on it. Hers does not.
• You got a sister. She is tiny, she sleeps a lot, and she thinks your funny face is the best thing in the house.
• A baby lives here now, and you are the big one who knows where the cups go. That job was already yours. It still is.
• Big brother, big news: the baby likes the blanket you picked. She grabbed it and would not give it back.

For older children and teenagers

An older child has watched a pregnancy happen for months and has usually formed a view. The cards that work at this age admit the obvious: nobody consulted them, the house is louder, the parents are distracted, and some of the next year will be tedious. That admission is what makes the congratulations believable. Skip any line about setting an example unless you would enjoy receiving it yourself at thirteen, in writing, from an adult relative.

• Congratulations on the new brother. You are old enough to be told plainly: some of this will be boring, some of it will be funny at 2 a.m., and you are allowed to say which is which.
• To a big sister of twelve years' standing in this family: the baby gets a card that says welcome. You get this one, which says we noticed your life changed too.
• You did not order a sibling, and the family survey was never sent. For the record, your sister arrived Tuesday and the house has been reorganising itself around two people ever since, not one.
• Big brother duties, official list: teach him the house rules you invented, deny inventing them, and keep the good headphones out of reach until at least 2031.
• Congratulations. Being the eldest used to mean first at everything. It now also means first to be asked what the baby needs, so this card carries an apology in advance.
• To the new big sister: you can hold her, feed her or hand her straight back. All three are correct answers, and anyone who tells you otherwise can hold her themselves.
• Your brother is here. In about fourteen years he will think you know everything. Enjoy the long run-up, and start deciding what you plan to do with that authority.

Written as if from the baby

A card in the baby's voice is the one format where a bit of theatre helps, because the older child is in on the joke from the first line. Keep the baby's powers modest. A newborn who writes in polished verse is an adult showing off, and children spot it. A newborn who reports sleeping, eating and an objection to baths, and who has somehow already heard that the older child is the main event, is funny in the right way and can say the proud things an adult card cannot say without sounding like pressure.

• From your sister, aged six days: I cannot hold a pen, say your name or keep my eyes open past ten minutes. I have been told you are the main event. I believe it.
• To my big brother, from the baby: thank you for the card you drew me. It is on the fridge, at your height, where I am told all important documents live.
• Hello from the small one. I sleep, I eat, I object to baths. When I can do more, you are first on the list of people I plan to do it with.
• From your brother, dictating this on day four: the grown-ups keep saying I look like you as a baby. I am taking that as the compliment they seem to think it is.
• To my big sister: Mum says you checked on me twice in the night and told nobody. Noted, and remembered for when I am old enough to return favours.
• I am new, I am loud, and I am yours, apparently. The paperwork the adults keep mentioning says sister. I say we start with the person who shares her crisps.

For a child who is finding it hard

Send these as their own card, not as a paragraph inside the parents' congratulations, and do not be tempted to finish them with a bright final line that takes the permission back. Advice aimed at parents has converged on the same few moves for years: greet the older child first when you visit, avoid blaming the baby for every limit, and let the child hear the baby being told to wait sometimes, so waiting is visibly shared. A card can do the written version of that. It can say, in plain words, that mixed feelings are allowed, that their place has not been reassigned, and that nobody worth listening to expects a performance.

• You do not have to be thrilled yet. The baby is here, your room is still your room, and this card is not going to pretend the last week has been easy for you.
• It is allowed to miss how things were. A lot of grown-ups miss it too, and they are the ones who arranged it. Your sister being here does not cancel any of that.
• To a big brother who is having a hard month: nobody sensible expects you to perform delight on demand. Come and meet him when you are ready. He will wait. He is mostly asleep.
• This card has no lesson in it. You have had a baby arrive in your house, your parents are tired and strange, and you are still you. That last part is the point of sending it.
• You are not the supporting act in this news. You are a person whose family changed shape this week, and the people who love you noticed that it changed for you too.
• If the baby feels like a visitor who will not leave, you are not the only older child in history to think it. It gets less strange. The visiting part, sadly, is permanent.

Short lines to add inside the parents' card

A separate card is better, and the banks above exist because of that. But if you are signing a family card, a group card or a card that will be opened in a hospital room with no time for a second envelope, a named line for the older child is a great deal better than the standard sentence about everyone being excited. Write their name. A line with a name in it gets read out. A line about siblings in general gets skimmed by every adult in the room, including the one it was meant for.

• And to the new big sister reading over a shoulder: this family's card has a line with your name on it, because the news is yours too.
• P.S. for the big brother: your sister has arrived safely, and the first photograph of the two of you is already the one your parents show people.
• One line for the eldest, before the baby takes the rest of this card: congratulations on the promotion nobody consulted you about. You are handling it better than the adults.
• To both children, in age order: welcome to the small one, and well done to the one who has been waiting, in various moods, since the spring.
• A note tucked in for a big sister: the baby is lucky in one specific way already, and it is not the house, the pram or the name. It is you.

Lines to leave out of a big sibling card

Well-meaning adults reach for these first, and each one lands differently on the child than it does on the sender. A blockquote, so none of them counts toward this bank:

You are so grown up now, you do not need as much fuss as the baby.

You will have to be a good example at all times.

You must love her already, she is your sister.

Mummy and Daddy needed a little helper, and that is you.

Each of those sentences takes something away while sounding like praise: time, freedom, the right to an opinion, a childhood with no job description. The repair is simpler than it looks. Congratulate the child on the news itself, name one thing that stays theirs, and stop writing while the card is still a present rather than a contract.

Turn it into a group card

A new baby in a family with an older child creates two audiences and usually one card, which is how the older child ends up as a footnote. A group card with several signers solves the arithmetic: relatives can each write a line, and one of them, briefed in advance, writes theirs to the big brother or big sister by name. You can create a card online in a couple of minutes, and the congratulations ecard pages cover the parents' side of the same news.

For the parents, the shipped congratulations on a new baby bank handles the main card, while the baby shower thank-you guide and the first birthday wishes bank cover the gifts that arrive around the birth and the milestone that comes round faster than anyone warns the older child it will.

My keys have lived on the same chipped enamel tray by the front door since 2019, beside a spare button for a coat I no longer own and a supermarket trolley token from a shop that closed two winters ago. I clear that tray out every spring, I tell people, and every spring the button and the token survive the clear-out for reasons I have stopped trying to explain to myself.
