What We AskHonest feedback after reading it together.

A Calmer First Step

Show it. Talk about it. Then try it together.

Potty training asks a toddler to do something unfamiliar with their body, in a new place, on an adult schedule. "Bye Bye, Diaper" gives parents a visual way to make the routine feel less mysterious before the next attempt.

Do This

Read It Together

Open a realistic story your toddler can connect to everyday bathroom routines and familiar objects.

Get This

Less Mystery

Give your child a chance to see the sequence and talk about what may happen before asking them to try.

Here Is How

Use Your Words

Pause on each scene and adapt the conversation to your child, your bathroom, and your chosen training approach.

Why KIDU Made This

Created from a real moment when preparation changed everything.

"When my child needed a procedure, a realistic, scripted story that showed what would happen step by step changed how prepared they felt. I kept thinking: why don't parents have the same kind of visual tool for everyday toddler milestones? Potty training was the first one that came to mind."
