Expert/company advocating this approach (if applicable):
Mom of 5, daycare for 7 years and a ECE degree.

Description of method:
When they are ready, they will let you know. All of my kids have been potty trained by 2 years old. Most children are potty trained by 3. My kids would take off their clothes and I would let them run around naked (or in underwear if they wanted) and tell them to go over to the chair and go potty... don't ever ask is the main thing!! Daycare kids would have underpants on. I never used "pullups" for any child. When they are ready, they will let you know!

Recommended age for this method:
20 months and above

How long should it take for child to be potty trained by this method?
2-3 days
