The day they became someone's big.

A story about the moment your family grew.

A Whimbel new sibling book tells the real story of the day your child became a big brother or sister — personalized illustrations from one photo, with a narrative that makes them the hero.

What makes this book special

Becoming a big brother or sister is one of the most transformative moments in a child's life. Instead of a generic template book, give them a real story — their story — about the day the family grew by one tiny, perfect person.

  • Tells the real story of meeting their sibling for the first time
  • Makes the older child the hero — they see themselves in every page
  • Helps process big feelings through a familiar bedtime story format
  • A keepsake both siblings will treasure as they grow up together

Why it matters

The look on their face when they first held their baby sibling. The gentle pat, the whispered hello. Don't let that moment live only in your camera roll.

Books that feature the child as the protagonist in a real family transition help them rehearse and process the change in a safe, predictable format.

Frequently asked questions

Can I include both children in the illustrations?

Yes! Upload a photo of each child and both will appear consistently throughout the book. The older sibling is typically the main character.

What if my child has mixed feelings about the new sibling?

That's completely normal and beautiful. The story can include the excitement, the nervousness, the adjustment — making it feel real and validating for your child.

Can I make this book before the baby arrives?

You can! Many parents create an anticipation story about the upcoming arrival. After the baby is born, you can create another book about the actual meeting.
