First, check whose word 'rainbow' is
Here is the thing nobody tells you at the card rack. Rainbow baby is the parents' phrase to use, not yours to assign. Some families say it with pride, print it on a vest, put it in the announcement. Others hate it, because it turns the baby who died into weather and the baby who lived into the reward for sitting out the storm. A clinician at Cleveland Clinic puts it plainly: not everyone wants a living child defined as a rainbow, or a lost child remembered as a storm. Both reactions are normal, and the same family can hold each one on alternate Tuesdays.
So take your wording from them. If their announcement says rainbow, your card can say rainbow back, and the bank below does exactly that. If their announcement just gives a name, a weight and a date, copy that plainness. It is not coldness. It is the family telling you the register they can bear, and matching it is the kindest piece of writing in this whole article.
I got this wrong once, in the safe direction, and it still cost something. My cousin Morag, in Ambleside, had a daughter in October 2022, eighteen months after her son Rowan was stillborn. I sent the plainest card I could write. Name, congratulations, love. Nothing else. She rang me in January, from a car park, because that is where these calls happen, and said the plain cards were the ones she could not keep opening. Everybody had been so careful not to mention Rowan that the pile on her mantelpiece read as if he had been quietly edited out. She kept three cards that year. All three said his name.
There is a quick test before you seal the envelope. Ask whether the parents would read your first line out loud to the baby in twenty years, in a kitchen, without having to explain or excuse any of it. Rainbow lines pass that test in rainbow families and fail it everywhere else. Plain joy passes it almost everywhere. A remembering line passes it when it is plain too, a name and a fact, not a little speech about grief. If a line needs a footnote about what you meant, it is the wrong line, however well you meant it.
When they use the word themselves: rainbow lines
These are for the families who claimed the term first, in their own announcement, their own words. Mirror it back without improving it. Do not add storm imagery of your own, do not extend the metaphor to rain, sunshine or pots of gold, and let one rainbow reference per card be the limit. Two is a theme. Three is a greetings card company.
- Welcome, Flora. Your mum and dad have waited and hoped and held their breath, and now you are here, in their arms, where the hoping was always pointed.
- A rainbow baby, your parents call you, and the name fits. All that colour after grey months. We are so glad you are home.
- She is here. After everything, she is actually here, asleep on somebody's chest and entirely unaware of the fuss. Congratulations, all of you.
- You hoped out loud when hoping felt risky, and you kept a space ready in this house and in your lives. She has filled it in person. Welcome, little one.
- For months the scan photos lived on the fridge under a magnet shaped like a strawberry. The real baby is better. Welcome home.
- Congratulations on your daughter. May her first year be gloriously ordinary: feeds, naps, laundry, and nobody asking her to be a symbol of anything.
- He is not a reward and he is not a replacement. He is himself, brand new, and we already love the face he makes at bath time.
- Your rainbow, your rules. If today is for trumpets, we will bring trumpets. If today is for quiet, we will whisper. Either way, we are thrilled he is here.
Joy first, and nothing about before
Sometimes the right card is a plain celebration. The parents who lost a baby at a scan nobody else knew about. The ones whose announcement was deliberately ordinary. The colleague whose history you half know and have no invitation to use. A card that shouts about the baby in front of you is never the wrong card, provided it does not shout first baby, or finally a parent, or any sentence that quietly reorders their family.
- Welcome to the world, Mairi. You have excellent timing, a strong grip on a finger, and parents who light up in a way we have not seen in a long while.
- Congratulations on your beautiful boy. Three kilos of him, a head of dark hair, and a cry that carries down the corridor. Perfect.
- She is here and she is gorgeous. That is the whole message, really. Everything else is us repeating it in different words.
- A new baby in the family at last. Send photos, accept casseroles, ignore the advice about sleep training that arrives by Friday.
- So happy for the three of you. He has his dad's ears and his mum's timing, arriving the one weekend nobody had plans.
- Welcome, little one. Your big cousins have been practising gentle hands on a teddy since August and are ready for inspection.
- Congratulations. May the night feeds be short, the coffee be strong, and the visitors be the sort who wash up before they leave.
- We heard the news and grinned like idiots in a supermarket queue. She is here, she is well, and you did it.
Quietly remembering the baby who died
For close family and the friends who were there for the worst of it, acknowledgement is usually the thing that lands. Use the lost baby's name if you know it and the family uses it. Keep it to a line, maybe two. The new baby still gets the top of the card and most of it. What you are writing is a footnote with a heartbeat: this child is remembered, by name, on the happiest week of the year, by somebody other than her parents.
- Welcome, Flora. Your brother Rowan is part of this family and part of today, and we are holding both things at once, joy for you and love for him.
- A sister for Rowan. We say his name on purpose, because he is hers too, and because today does not shrink him. Congratulations, with all of it felt at once.
- She is not here instead of anyone. She is here as well as, and the as well as matters. Welcome, darling girl.
- Thinking of Rowan today as we meet his little sister. Two children, one family, and room in this card for both of them.
- Congratulations on your daughter. We remember the baby you lost, we have not stopped remembering, and meeting her does not ask us to.
- For the parents who carried two stories into that delivery room: we see both. Welcome to your daughter, and Rowan, you are not forgotten on her birthday.
- May she grow up hearing her brother's name said easily at the table, the way you say it. That is a good house to grow up in.
- Joy and grief in the same week is an exhausting address to live at. We are bringing food, we are saying both names, and we are not going anywhere.
Short lines for a small card or a tag on flowers
Gift tags and the little cards that come with flowers give you about twenty words before your handwriting gives out. Short does not have to mean empty, though. One specific thing, the wait, the name, the family shape, does more work in fifteen words than a paragraph of general wonder does.
- She is here. That sentence took a long time to arrive, and it was worth every day of the wait.
- Welcome, little one. You were hoped for by name long before you had one.
- Congratulations, with everything we felt before folded quietly into it.
- A baby at last, and she is entirely herself. We could not be happier for you.
- Hello, gorgeous boy. Your parents are besotted and the group chat is in pieces.
- Welcome home, all of you. Especially the smallest one.
- So much love to the family that grew by one this week, and holds its shape around everyone it has known.
For a colleague, where you know some of it and not all
At work you may know there was a loss because of last year's leave, a collection, a sentence in a kitchen. Knowing is not the same as being given the story. Keep the office card on the baby, the leave and the biscuits. If you want to acknowledge anything, do it in person and briefly, or not at all. Never in the card that fourteen people sign and the office manager photocopies for the file. Yes, that happens.
- Wonderful news, congratulations on your daughter. Enjoy every minute of leave, the inbox will survive without you.
- Delighted to hear your son arrived safely. Wishing you broken sleep, unbroken biscuits, and a very slow return to email.
- Congratulations from all of us on the desk pod. There is a card doing the rounds and a collection you are not allowed to refuse.
- Brilliant news about the baby. Take the full leave, send one photo if you feel like it, and none if you don't.
- So pleased for you and your family. Welcome to your little girl from the whole team.
- Congratulations. May your return date feel a long way off and the coffee machine here miss you as much as we will.
- Hearing your news was the best part of a grey Monday. Congratulations on your son, and enjoy the bubble at home.
- A new baby, how lovely. Wishing you all well, and please pass our love to your partner, whom half of us have never met and all of us admire.
Timing is the other half of the colleague question. Send the office card when the office sends it, in the first week or so, and keep it boring in the best way. Save anything personal for much later, if it ever fits at all. Plenty of parents say the messages that stayed with them arrived at the first anniversary of the loss, or on the due date that never became a birthday, long after the new baby cards stopped. A colleague who remembers a date like that, privately and without making a meal of it, has done something no group card can do.
From grandparents, and lines an older sibling can hear
Grandparents carry a double version of this. They grieved a grandchild and watched their own child grieve, usually while being told to stay cheerful and useful. Their cards can say more, because they were inside it. Older siblings are the other audience everyone forgets. A child who knows there was a baby before needs the new arrival's card to leave their knowledge intact, not talk over it.
- A granddaughter at last, and a sister for the grandson you talk about with that catch in your voice. Both of them are lucky in their grandparents.
- To the big sister: your baby sister is small, loud, and yours. You get to teach her the biscuit tin rules, which is the senior job in any house.
- Congratulations, Grandma. You kept every scan photo and every hope off the group chat, exactly as asked. Now you may show everybody everything.
- For the older brother who asked if the baby would know about Rowan: yes, love, because this family says his name. You can say it to her too.
- A nephew for us and a second grandchild for Mum and Dad, who are holding him like glass and beaming like teenagers. Family maths has never been better.
- Welcome, little cousin. Your aunties are already arguing about who held you first, and your big brother is keeping score in a notebook.
- To the grandparents who waited through the hard years without once making it about them: look what your patience gets to hold.
- Big sister, your card is the one with your name written largest, because you have been promoted and promotions should be announced properly.
Lines to leave out, and why each one stings
Every line below was written by somebody kind. That is the problem. Kind people reach for the nearest comforting shape, and in this territory the nearest shapes are at least, a reason, and a replacement, and all three ask the parents to agree that the loss has been settled by the arrival. Read them once, then write around them.
At least you know you can carry a baby now.
Everything happens for a reason, and she is the reason.
He has fixed everything, hasn't he?
Time to put the sad chapter behind you and enjoy this one.
She will never replace him, but she comes close.
Now you finally have a real family.
At least turns a dead baby into a down payment. A reason asks the parents to co-sign a philosophy at the exact moment they are holding the counterexample's sister. Fixed, replacement and real family all do the same quiet demotion, putting the new baby in a dead child's job. If a sentence would sound wrong read aloud at the lost baby's grave, it is wrong in the new baby's card too.
Turn it into a group card
A group card suits this arrival better than most, because it lets people choose their own register. The aunt who says Rowan's name can write her line. The cousin who only trusts jokes can write his. Nobody has to agree a house wording for an experience they did not share, and the parents get one envelope instead of thirty separate negotiations with other people's feelings.
Put the lines on a free congratulations ecard with room for everyone, or create a card online and send the link round the family. One practical rule for whoever organises it: read every line before it goes. Group cards are where an at least line slips in, written by the kindest uncle in the family, in biro, at the last minute.
When the baby is older, the sibling banks on this site may help: the card for a first birthday sits at 1st birthday wishes, and the thank-you notes after the party are covered by what to write in a baby shower thank you card. For the mother herself, whenever her own day comes round, there is what to write in a Mother's Day card.
Morag still has the three cards that named Rowan, in a box with his hospital bracelet and a photograph nobody outside the family has seen. Flora's cards went in the same box last spring, which I only know because Morag told me, laughing, that the box is now mostly her daughter: drawings, a first shoe, a lock of hair in an envelope marked in pencil. Rowan's end of it has not shrunk. It turns out a box, like a family, does not work on a fixed capacity. Things just get moved around to make the new shape fit, and every so often something at the bottom gets taken out, looked at, and put back more carefully than it was stored.
