New Baby Sibling Story Book Prompts for Big Brothers and Sisters
A new baby sibling story book gives the older child a place to put their feelings, excitement, jealousy and missing the old way, and shows them where they fit now. These prompts end with the big sibling finding a role only they can play. Parents buy them before the due date, and they are a popular personalised gift on Etsy and a steady KDP niche.

Bao, a little boy in a striped T-shirt with a toy drum, has always been the loudest in his family. Then baby sister Lin arrives, and she's even louder. She cries at breakfast, at bath time and in the middle of the night, and Mama and Baba are too tired to play. Bao bangs his drum to drown her out, and Lin stops crying to listen. So Bao taps soft, slow rhythms, and Lin falls asleep. Now Bao has a new job: the family's baby drummer.
Why it works: Toddlers whose world just got noisier get a funny story that gives them a special job, a lovely baby-shower gift.

Olive, a small hedgehog with a pink acorn hat, loves Mama's lap more than anything. But Mama's tummy grows and grows until there's no lap left. Then the baby comes, and the lap is full of baby. Olive tries Papa's lap, Grandpa's lap and even the cat's back, but none are quite right. One evening, Mama makes room: baby on one side, Olive on the other, and a story for both. Olive learns there's always room for her.
Why it works: Parents expecting a second baby get a soft, honest story about the exact thing toddlers fear losing.

Marcus's big brother handbook

Marcus, a seven-year-old with a high-top fade and a notebook, decides to write the official Big Brother Handbook before his baby brother Miles arrives. Rule one: babies are boring. Rule two: never share your room. But as the weeks pass, each rule gets crossed out: Miles grabs his finger, laughs at his faces and falls asleep on his chest. By the last page Marcus's handbook has only one rule left, in big letters: be the best big brother ever.
Why it works: Older siblings who think they're too big for baby books get humor and comic panels, and parents get a sweet arc.

Tips for making a new baby sibling story book
Include one page where the older child feels left out, and one where a grown-up makes time just for them.
Use the family words the buyer uses (Mama, Mum, Mom) in the brief.
Make the ending a job only the older child can do, not just a hug.

Start from one of these prompts or write your own. InkChamps turns it into a print-ready PDF.
