The 10 Best Big Brother Books for Toddlers (2026)
By the Little Hero Book team · Updated July 2026
A new baby is wonderful news for everyone except, occasionally, the toddler whose universe it just rearranged. The right book helps: big brother books give little boys the words for feelings they can't explain yet, and turn "the baby is coming" from a threat into a promotion.
We read a lot of them. These are the ten best big brother books for toddlers and preschoolers, from board-book classics to the personalized kind where your own son is the hero. (Shopping for a girl? Here's our big sister book list and the personalized big sister book. Most classics below also exist in a sister edition.)
Quick picks
- Best overall: A personalized big brother book starring your son
- Best board book: I Am a Big Brother by Caroline Jayne Church

1. Your Own Personalized Big Brother Book
Little Hero Book · Ages 2–8
Every other book on this list stars someone else's kid. This one stars yours: upload a photo, and your son becomes the illustrated hero of "The Loudest House", where the new baby will not settle and he is the only one who can help. For a toddler wrestling with a new baby taking all the attention, a book where HE is the main character lands differently than any classic can.
Best for: The big brother who needs to feel like the star, not the sidekick.
Create His Book · $34.992. I Am a Big Brother
Caroline Jayne Church · Ages 1–4
The modern go-to board book. Short, sweet, sturdy pages and Church's instantly recognizable round-faced toddlers. It frames the new baby as exciting rather than threatening, in language a two year old can follow on the first read.
Best for: The youngest big brothers. It survives being chewed.
3. I'm a Big Brother
Joanna Cole · Ages 2–5
The classic that named the category. Gentle, reassuring, and honest about the mixed feelings a new sibling brings, with a helpful note for parents in the back about easing the transition.
Best for: Parents who want a little guidance included.
4. Peter's Chair
Ezra Jack Keats · Ages 3–5
A picture-book landmark from 1967 that still works because it takes toddler jealousy seriously. Peter watches his old crib and high chair get painted pink for the new baby, and decides to run away (as far as the front stoop). The ending, where he chooses to give up his chair himself, says more about growing up than most parenting books.
Best for: The big brother who is not thrilled about any of this.
5. The New Small Person
Lauren Child · Ages 3–6
From the creator of Charlie and Lola: Elmore Green enjoys being an only child very much, thank you, until a new small person arrives and starts licking his jelly-bean collection. Funny, stylish, and quietly moving when the two finally become a team.
Best for: Kids who respond better to humor than to reassurance.
6. You Were the First
Patricia MacLachlan · Ages 2–5
Less about the new baby, more a love letter to the firstborn: first smile, first steps, first to make mom and dad parents at all. Read it to your big brother the night before the baby arrives and try not to cry.
Best for: Reminding the firstborn he was never replaced.
7. My New Baby
Rachel Fuller · Ages 1–3
A nearly wordless board book that lets the pictures do the talking: a toddler watches the baby feed, cry, bathe, and nap. Because there is so little text, you can shape the story around your own family every time you read it.
Best for: Pre-verbal toddlers and flexible storytime.
8. There's a House Inside My Mummy
Giles Andreae · Ages 2–5
The one to read during the pregnancy, before the baby arrives. A little boy describes the "house" inside his mummy where his sibling is growing, in bouncy rhyme that toddlers memorize fast.
Best for: Preparing a big brother while the baby is still on the way.
9. The Berenstain Bears' New Baby
Stan & Jan Berenstain · Ages 3–7
Small Bear has outgrown his little bed, and it turns out someone smaller is about to need it. A warm, familiar-feeling classic that frames growing up and gaining a sibling as the same happy thing.
Best for: Families who grew up on Bear Country themselves.
10. Big Brothers Are the Best
Fran Manushkin · Ages 2–5
A simple, sunny celebration of the job itself: big brothers show the baby their toys, make silly faces, and help out. No conflict, no jealousy, just pride. A good pick when you want pure positivity.
Best for: The already-enthusiastic big brother.
How to Choose a Big Brother Book
Match the book to the moment. During pregnancy, pick a "baby is coming" story like There's a House Inside My Mummy. At the birth, give a celebration of the new title. That's where a personalized book or Big Brothers Are the Best shines. If jealousy shows up later, reach for Peter's Chair or The New Small Person, which take those feelings seriously instead of talking over them.
Match the book to the age. Under three, sturdy pages and few words win. From three up, your big brother can handle a real plot, and by five or six he can read his book aloud to the baby himself, which is the whole payoff.
Big Brother Book FAQ
When should I give my toddler a big brother book?
Earlier than you might think. Reading sibling books during the pregnancy, around the time you tell your child about the baby, gives the idea months to settle in. Then a special "big brother" book as a gift when the baby arrives marks the promotion.
What age are big brother books for?
Most are written for ages 1 to 5, since that is when a new sibling most often arrives. Board books like "I Am a Big Brother" suit ages 1–3; story-driven picks like "Peter's Chair" work best from 3 up. Personalized books span the widest range because the story is matched to the child's age.
Should the big brother book be a gift "from the baby"?
It is a beloved trick: sign the book from the new baby and give it at the hospital or homecoming. On a day when every visitor is focused on the newborn, the big brother gets something that is entirely his.
