Unpotty Training

I came across this new phrase while browsing/reading an article.

There was a sentence: "She Un-Potty trained my daughter while I was away". So, I browsed for the meaning of it and found that it was the toilet training imparted to babies.

I was fascinated by the answer that I received from AI.

Here is the answer I received for my question: 

"The average age to start toilet training is between 2 and 3 years old, and most children are fully trained by age 4. Some developmental readiness signs for potty training include:

• Being able to get to the toilet on their own
• Being able to sit down on the toilet
• Being able to pull their pants up and down
• Being able to communicate when they need to go"
