New sibling

A book that makes them proud to be the big one.

Welcoming a new baby? HeroKid.AI writes a personalized story where your older child is the brave, kind big brother or big sister — so the new arrival feels like a promotion, not a replacement.

Eases the transition

Reading it before baby arrives gives your older child a clear, hopeful picture of what's coming.

Their face on every page

It's not a generic 'big sibling' book — it's their book, with their hero on every page.

Keepsake forever

Years later, they'll still have the book that made them the proudest sibling in the world.

Read it the week before baby

Or the day you bring the baby home. Or both. The story turns "everything is changing" into "I get to be the hero of this story."
