New Sibling Personalized Children's Books
Where your child becomes the caring big brother or sister in their own family story.
Welcoming a new baby into the family is one of life's most joyful milestones—but for your older child, it can also bring big feelings of uncertainty, excitement, and change. Our personalized new sibling books are designed to help your child feel included, proud, and emotionally prepared for this important family transition. Each story stars your child as the caring big brother or sister, celebrating their new role while gently acknowledging the mix of emotions that come with it.
Unlike generic sibling books, Leo Books creates truly personalized stories that include your child's name, the baby's name or nickname, and even family-specific details like parent names and pets. These aren't just books about becoming a sibling—they're books about YOUR family's unique story. Whether your child is a toddler learning what it means to be gentle or an older sibling ready to take on helper responsibilities, our stories meet them exactly where they are emotionally and developmentally.
These milestone books make wonderful gifts from parents, grandparents, or extended family members who want to support your older child during this transition. They're perfect for reading together during pregnancy to build excitement, or after baby arrives to reinforce positive feelings and helpful behaviors. Most importantly, they send a powerful message: you're still special, you're still loved, and you have an important role in this family.

Frequently Asked Questions
Can we include both parents and the baby's name/nickname?
Absolutely! Personalization is at the heart of what makes Leo Books special. When you create your new sibling book, you can include both parents' names (or whichever caregivers are primary in your family structure), your older child's name, and the baby's name or nickname—even if baby hasn't arrived yet. Many families choose to use a nickname or "baby" during pregnancy and can request updated versions once the baby's name is chosen. This level of customization helps your child see their actual family in the story, making the emotional connection and preparation much more powerful than generic sibling books ever could.
Can we tailor it for toddler vs older sibling?
Yes, we strongly recommend age-appropriate tailoring! Our story generation takes into account your child's age and adjusts both the complexity of the narrative and the emotional themes accordingly. For toddlers (ages 2-4), stories focus on very concrete actions like gentle touching, fetching items, and simple cause-and-effect (baby cries, we use quiet voices). The language is simpler and more rhythmic, with rhyming elements that toddlers love. For older children (ages 5-8), stories can explore more complex emotions like jealousy, patience, and the long-term sibling relationship. They can handle narratives about waiting, sharing parental attention, and the responsibility that comes with being a role model. The illustrations also adapt—simpler and bolder for younger children, more detailed and nuanced for older kids.
Can the book address jealousy gently (without shaming)?
This is one of the most important aspects of a good sibling preparation book, and we take it very seriously. Jealousy is a completely normal response to a new sibling, and our stories validate these feelings rather than shame them. We use age-appropriate language to acknowledge that sometimes big siblings might feel left out, wish they had more mommy or daddy time, or feel frustrated when the baby gets lots of attention. The stories then model healthy ways to express these feelings and show parents responding with understanding and reassurance. For example, a character might think, "Sometimes I wish it was just me and Mommy again," and a parent might respond, "I love our special time together too. How about we plan something just for us tomorrow?" This approach teaches emotional literacy and shows children their feelings are valid while guiding them toward positive coping strategies.
Can siblings both be "stars" (not one replacing the other)?
This is fundamental to our sibling story philosophy. We never position the new baby as "more special" or frame the older child as needing to "step aside." Instead, our stories emphasize that families grow, love multiplies, and each person has their own special place. We often use metaphors like "two stars in our family sky" or "each puzzle piece is important." The stories highlight what makes the older child uniquely wonderful—their skills, their personality, their history with the family—while also welcoming the new baby's arrival. We're careful to show parents continuing to celebrate the older child's milestones, spending one-on-one time with them, and explicitly stating that the older child is loved just as much as always. The message is always: you're not being replaced, you're being joined by a teammate.
Can we include pets as part of the family?
Yes! Pets are family members, and many children feel a special kinship with family pets during the transition to big siblinghood. If you include your pet's name and species in the book customization, we can weave them into the story as a fellow family member who's also adjusting to the new baby. For example, your family dog might also learn to be gentle around the baby, creating a parallel that helps your child feel less alone in their adjustment. Or the cat might become the older child's special companion during quiet times when baby is sleeping. Including pets adds another layer of personalization and can be especially comforting for children who are very attached to their animals. It reinforces that the whole family—pets included—is going through this change together.
Can the story be extra calming for bedtime?
Definitely. If you select a calming tone option, we can create a version of your sibling story that's specifically designed for bedtime reading. These versions have gentler pacing, more soothing language, and peaceful resolutions. They might focus on quiet activities like reading together, gentle snuggles with the baby, or bedtime routines that include both children. The emotional content is still meaningful but presented in a reassuring, settled way that won't create bedtime anxiety or overstimulation. Many parents find that a calming sibling book becomes part of their older child's bedtime routine during the transition period, offering both comfort and positive reinforcement right before sleep. Stories like "The First Snuggle Story" or "The Sibling Song" work particularly well as bedtime reads.
