Who we are

We’re a family of storytellers, twin parents, and ocean dreamers.

The Twin Fins series was created by Kanika Gupta, a mom of twin boys (and a very lovable dog named Jimmy), who wanted to give young children stories that feel as gentle and real as their everyday emotions.

Each book is inspired by the tender, funny, and often chaotic moments of toddlerhood — especially the unique joys and challenges of raising twins. With rhyming text, lovable characters, and a deep understanding of little hearts, we aim to create books that help children feel seen, supported, and brave.

At Twin Fins, we believe that stories can do more than entertain — they can teach empathy, build confidence, and strengthen the bond between parent and child.

We’re so glad you’re here. Dive in and grow with us — one splashy story at a time.
