How do you potty train a toddler?
Unfortunately potty-training a toddler doesn't happen when you want it to happen, but when your toddler decides it's time. And most likely, at the beginning, she’ll be interested in the idea one day and disinterested the next.
How to tell your toddler is potty trained
There are a few ways to tell if your child is on her way to being potty-trained though — for example: She's comfortable enough with walking that she’d be able to take herself to the bathroom as needed. Dirty diapers make her uncomfortable, and she requests that you change her. She tells you she wants to wear "big-kid" undies. And she expresses curiosity about the toilet habits of grown-ups.
Once you're seeing those signs, it couldn't hurt to suggest the potty whenever you notice in her facial expression or behavior that she needs to use the toilet.
