The concept of "toilet training readiness" was pioneered by pediatricians like Benjamin Spock and T. Berry Brazelton (Brazelton et al 1999).
Spock and Brazelton argued that some children are pushed into training before they are ready. As a remedy, these practitioners proposed a child-oriented approach to potty training.
According to this idea, children, not parents, should lead the way. Today, the child-oriented approach is very popular, and many authors have suggested their own signs of toilet training readiness.
Do you really need to wait for these signs? No. As I argue below, your decision to wait should depend on your goals and expectations. Moreover, many of the signs concern learned behavior. So you don't have to play a passive waiting game. You can take active steps to teach your child what he or she needs to know.
But what exactly do the toilet training experts want you to look for?

Most experts recommend that you should wait until your child is
After that, opinions vary.
The American Academy of Pediatrics
The American Academy of Pediatrics (2006) has published a checklist of signs to help you determine when to start potty training. Here is an excerpt:
Peter Gorski, M.D., Massachusetts Caring For Children Foundation
A somewhat different list of signs is offered by Peter Gorski (1999), director of the Massachusetts Caring for Children Foundation. In an article for the medical journal Pediatrics, he proposes these signs:
Other sources suggest more signs of toilet training readiness, such as
When to start potty training: Should you wait for the signs?
If you’ve skimmed these checklists, you probably noticed several key points.
First, these signs of readiness presuppose that you want to train for complete potty training independence.
If you’re going to ask your child to walk to the bathroom, then clearly you need to wait until he can walk. But if you’re interested in the more modest goals of infant potty training, you don't need to rely on these signs to decide when to start potty training. Most of these “readiness” signs don’t apply to your situation.
Second, the lists vary considerably.
Depending on which expert you consult, your child may or may not be ready. In a recent study reviewing all the published signs of toilet training readiness, researchers concluded there was no good consensus, and that parents might begin toilet training at very different times depending on which signs they relied upon (Kaerts et al 2012).
Third, and most importantly, many of these signs concern learned behaviors.
They can be encouraged or taught by parents. And they probably should be. If parents wait passively for children to learn how to undress themselves, or to show curiosity about the toilet, they may wait for a long time.
In a recent study of American children, aged 15-40 months, most toilet-related skills were not mastered until after 22 months, and the median age for attaining some skills—like telling a parent before having a bowel movement—was over 31 months (Schum et al 2002).
That’s a very long time if you consider that
“median” means that half the kids took even longer.
are no specific studies published on the subject, it seems likely that
parents can speed things up by teaching readiness skills. Barton
Schmidt, Professor of Pediatrics at the University of Colorado, says
that one of the most common mistakes parents make is doing nothing to
prepare until the week they start training (Schmidt 2004).
