When to Start Potty Training: The Readiness Analyst Framework

Every parenting group on the internet will give you a different answer about when to start potty training. "We did it at 18 months!" or "Wait until they are 3, or you'll ruin them."

The problem with all of this advice is that it is fundamentally based on other people's children.

If you want a potty training project that takes weeks instead of months (or years), you have to stop looking at age charts and start looking at the data in front of you.

The Readiness Analyst

The biggest mistake we make is starting when we are ready—usually because we're tired of buying diapers, or preschool requires it—instead of when they are ready.

You need to become the Readiness Analyst. This means putting your own timeline aside and conducting a neutral audit of your child's physiological and cognitive development.

The Four Signals You Actually Need

You don't need all of these, but you need most of them before you begin:

• The 2-Step Instruction: Can they follow a command like, "Pick up the block and put it in the box"? If they cannot follow a 2-step instruction, they cannot go to the bathroom.
• The Awareness Signal: Do they announce when they are wet or dirty? Do they hide behind the couch to poop? This means the brain-body connection is firing.
• The Dry Stretch: Are they waking up dry from naps, or staying dry for 2+ hours at a time? This is bladder capacity.
• The Motor Capability: Can they physically pull their pants down and back up?

Observe First, Execute Second

To successfully train your child, you need to collect data on their baseline behavior before you introduce the toilet. The Readiness Analyst approach requires patience up front, but it yields a dramatically faster implementation phase.

Wait for the data. The charts don't matter.
