Some parents affirm that they find out evidences of their under 1 year old child is able to use small toilets, asserting their child has been successfully potty trained.

There are some signs about when a child is ready for potty train; for example, being able to walk by himself, can sit on and get off from chair by himself, can keep diapers dry for several hours, being able to follow some simple orders, feeling uncomfortable when diaper is wet. Usually, girls show up these signs earlier than boys.
