Preparing Your Toddler for a New Sibling with a Personalized Book

A new baby is thrilling for parents and confusing for toddlers. The child who used to have your undivided attention is suddenly sharing it — and they don't have the words for how that feels. A personalized story can give them those words, and turn anxiety into pride.

Why big-sibling worry happens

To a toddler, a new sibling can feel like a rival, not a gift. Common (and completely normal) reactions include clinginess, regression, big emotions, and testing boundaries. What helps most is feeling prepared and feeling important — two things a story is uniquely good at delivering.

How a story helps

A book lets a toddler rehearse a big change safely, before it happens. Reading about a character who becomes a big sibling — and who is loved just as much afterward — answers the questions they can't yet ask:

• Will I still be loved?
• What will the baby be like?
• What's my job now?

When that character shares their name and face, the reassurance lands even deeper. It's not a story about a big sibling — it's a story about them.

The goal isn't to explain the baby. It's to promise the toddler they still belong.

What to put in the book

• Their new title. Frame "big brother" or "big sister" as an exciting promotion.
• A real job. Small, proud roles: picking a bedtime book for the baby, singing a lullaby, being the one who makes the baby smile.
• Honest feelings. It's okay to show the hero feeling unsure — then feeling better.
• Unchanged love. End on the clearest possible message: there's more than enough love to go around.

When to start reading it

Begin a few weeks before the due date and read it often, so the ideas feel familiar by the time the baby arrives. Keep reading it afterward, too — it's just as reassuring in the messy first weeks at home.

Make their big-sibling book
