"We were so worried about how our 3-year-old would handle having a new baby. This book changed everything. She started calling herself 'the best big sister' even before the baby arrived."
Amanda K.
Mom of Emma (4) and baby Noah
"The personalized aspect made all the difference. My son actually paid attention because he was the hero of the story. He references 'what he did in his book' when he helps with his baby sister."

Everything you need to know about preparing your child for a new baby.
A new sibling book is a personalized storybook designed to help prepare children for becoming a big brother or big sister. Unlike generic books about new babies, a personalized new sibling book features your child as the main character — making the story directly relevant to their experience. The book shows them being kind, helpful, and excited about their new role, helping them visualize and embrace the upcoming change.
Preparing a child for a new sibling involves several strategies: talking openly about the baby, involving them in preparation, reading books about becoming a big sibling, and addressing their feelings. A personalized book is especially effective because it makes your child the hero of the story — they see themselves handling the transition positively, which helps build their confidence and excitement about their new role.
New sibling books work well for children ages 2-8, with the 2-5 age range being most common. Toddlers (2-3) benefit from simple stories with clear pictures. Preschoolers (3-5) can understand more complex emotions and story elements. School-age children (6-8) may appreciate more detailed adventures. Custom Heroes adapts the story complexity to your child's age.
Yes, research shows that children process emotions through stories. A personalized book helps because children see themselves succeeding as a big sibling before it happens. This 'bibliotherapy' approach helps normalize mixed feelings, provides a safe space for discussion, and creates positive expectations. Many parents report their children referring to 'what they did in their book' when meeting the real baby.
Start reading about the new baby 2-3 months before the due date. This gives your child time to process the information gradually without feeling rushed. Continue reading the book after the baby arrives — it becomes even more meaningful when they can relate the story to their real experience.
A personalized book where they're the hero is one of the best gifts for an older sibling because it: 1) Acknowledges their important new role, 2) Makes them feel special during a time when attention shifts to the baby, 3) Creates something that's 'just theirs' when so much is changing, 4) Becomes a keepsake they'll treasure. Many parents present it as a 'big sibling gift' during the hospital visit or homecoming.
New sibling jealousy is normal. A personalized book helps by validating that mixed feelings are okay while showing positive outcomes. Reading together creates opportunities to discuss emotions. The book also gives you language to use: 'Remember how (character) felt in your book?' Other tips: maintain one-on-one time, involve them with baby care, and praise their 'big sibling' moments.
Yes! If your baby has already arrived, you can include photos of both children in the story — creating a book about their adventures together. If the baby hasn't arrived yet, the story focuses on your older child and their journey to becoming a big sibling, with the new baby as a character they'll meet.
If your child is struggling, the book becomes a therapeutic tool. Reading it together opens conversations about their feelings. You might say, 'The character in your book felt worried too — do you ever feel like that?' The book normalizes their emotions while consistently showing a positive outcome. For persistent difficulties, the book can complement advice from your pediatrician.
Regular big sibling books feature generic characters, while a Custom Heroes book stars your actual child with custom illustrations of them. This personalization makes the story directly relevant — children pay more attention and connect more deeply when they see themselves in the book. You can also customize the story to address your family's specific situation and your child's particular interests or concerns.
Personalized new sibling books from Custom Heroes start at $34 for a 12-page softcover book, which includes the printed book and digital PDF. Longer books (16 and 20 pages) and hardcover options are available up to $59. There are no subscriptions or hidden fees — just a one-time purchase for a meaningful gift that helps your family through this transition.
