The 10 Best Big Sister Books for Toddlers (2026)
By the Little Hero Book team 路 Updated July 2026
Most of the family is delighted about the new baby. The three-year-old is usually less sure. She doesn't have words yet for what she's feeling, and a book is one of the few things that will hand them to her without turning it into a conversation she has to sit through.
We went through a lot of these. Below are ten worth the shelf space, for toddlers and preschoolers: board books, a few proper classics, and the personalized kind where your own daughter is the one in the pictures. Shopping for a boy instead? We keep a separate big brother book list, and most of the classics below have a brother edition too.
Quick picks
- Best overall: A personalized big sister book starring your daughter
- Best board book: I Am a Big Sister by Caroline Jayne Church
- Best classic: Julius, the Baby of the World by Kevin Henkes
- Best during pregnancy: Waiting for Baby by Rachel Fuller
- Best for real jealousy: A Baby Sister for Frances by Russell Hoban
1. Your Own Personalized Big Sister Book
Little Hero Book 路 Ages 2 to 8
Every other book here is about somebody else's family. This one is about yours. You upload a photo and your daughter gets drawn into "The Loudest House", a story where the new baby won't settle and she's the one who works out how to fix it. If she's spent the last month watching a newborn collect all the attention in the room, a book with her own face in it does something the classics can't.
Best for: A big sister who needs to be the main character for once.
Create Her Book 路 $34.992. I Am a Big Sister
Caroline Jayne Church 路 Ages 1 to 4
This is the board book most parents end up with. Church draws those round-faced toddlers you've seen on a dozen other covers, the pages survive a two-year-old, and the whole thing takes about ninety seconds to read. The baby comes across as exciting rather than as a threat, which is the entire job.
Best for: Ages one to three. It holds up to being chewed.
3. I'm a Big Sister
Joanna Cole 路 Ages 2 to 5
Cole's book has been the default gift for new big sisters since the 1990s. It reassures without pretending any of this is easy, and there's a note for parents in the back with practical advice about the first few weeks at home.
Best for: Parents who want some coaching alongside the story.
4. Julius, the Baby of the World
Kevin Henkes 路 Ages 3 to 7
Lilly hates her new baby brother. She says so out loud, repeatedly, and runs a small campaign to get rid of him. Then her cousin Garland turns up and insults Julius, and Lilly discovers that she is the only person on earth allowed to do that. Henkes never once tells the reader that jealousy is wrong, which is why kids believe the ending.
Best for: The big sister who is not on board with any of this.
5. A Baby Sister for Frances
Russell Hoban 路 Ages 3 to 7
Written in 1964 and still completely readable. Baby Gloria arrives, nobody buys raisins anymore, and Frances decides to run away. She makes it as far as under the dining room table, close enough to overhear her parents talking about how much they miss her. That's the whole point of the book, and Hoban lets the kid get there herself.
Best for: A firstborn who needs to hear that somebody noticed she was gone.
6. Za-Za's Baby Brother
Lucy Cousins 路 Ages 2 to 5
Lucy Cousins of Maisy fame, so you already know what the artwork looks like: thick black outlines, color filling the whole page. Za-Za waits out the pregnancy, the baby arrives, and suddenly her mum's lap is occupied. She gets it back by the end. Not much more plot than that, which is right for the age.
Best for: Maisy fans who need the feeling put into words for them.
7. You Were the First
Patricia MacLachlan 路 Ages 2 to 5
The baby barely appears. MacLachlan spends the whole book on the firstborn instead: her first smile, her first steps, the fact that she's the one who turned two people into parents. Read it the night before the hospital and see how you do.
Best for: The night before, when she needs reassurance rather than information.
8. Waiting for Baby
Rachel Fuller 路 Ages 1 to 3
Almost no text. A toddler puts a hand on the bump, helps get the crib ready, and waits. Since the pictures do the work, you end up narrating it yourself, so you can put your own family's details in and change them as things actually happen.
Best for: The months before, while the baby is still theoretical.
9. The Berenstain Bears and Baby Makes Five
Stan & Jan Berenstain 路 Ages 4 to 8
Sister Bear had the youngest-child job locked down until Honey Bear turned up, and she does not take the demotion well. If your kid already knows the Berenstains, this one goes down easily, and it covers a version of jealousy the other books here mostly skip.
Best for: A child who is about to become the middle one.
10. Big Sisters Are the Best
Fran Manushkin 路 Ages 2 to 5
Nothing goes wrong in this book. The big sister shows the baby her toys, pulls faces to make him laugh, helps out at bath time. Some kids don't need their jealousy validated because they aren't jealous, and this is the one to buy them.
Best for: A big sister who's already thrilled and wants to read about it.
How to Choose a Big Sister Book
Timing matters more than the specific title. While you're still pregnant you want a book about a baby that's coming, like Waiting for Baby. Once the baby actually arrives, switch to something that makes a fuss of her new job, which is where a personalized book or Big Sisters Are the Best earns its place. Then wait. The jealousy usually shows up around week three or four rather than on day one, and that's the point at which Julius or Frances starts being useful.
Age is the other thing to check. Under three you want thick pages without many words on them. From three up she can follow an actual plot. By five or six she'll read the book to the baby herself, which is worth the whole exercise.
Big Sister Book FAQ
When should I give my toddler a big sister book?
Start during the pregnancy, roughly when you tell her about the baby. That gives the idea a few months to become normal instead of arriving as news. Then hold one book back to give her on the day the baby comes home, so something marks the change for her specifically.
What age are big sister books for?
Most sit between one and five, since that is when a sibling usually turns up. Board books like "I Am a Big Sister" work from about one to three. Story-driven ones like "Julius, the Baby of the World" need a three-year-old at minimum. A personalized book covers a wider range because the story gets matched to her age.
Should the big sister book be a gift "from the baby"?
It is a well-worn trick and it works. Sign it from the baby and hand it over at the hospital or once you get home. Every adult in the room is going to be looking at the newborn that day, and this gives her one thing that is hers.
Do books really help prepare a toddler for a new baby?
They help more than talking about it does. You cannot really discuss a hypothetical sibling with a two-year-old, but you can read her a story about one twenty times, and the repetition does the work. Keep reading them after the birth as well. The hard part tends to come a few weeks in, once the visitors stop.
