What is the term for the process of children learning to control their bodily functions?

Toilet training is the term that specifically refers to the process in which children learn to control their urination and defecation, transitioning from using diapers to using the toilet. This developmental milestone typically occurs between the ages of 2 to 3 years, although readiness can vary from child to child. Proper toilet training can enhance a child's independence, self-esteem, and hygiene practices.

This term encompasses not only the physical skills required for using the toilet but also the psychological readiness and social learning aspects involved in this process. Children learn cues for when they need to use the bathroom, how to communicate this need, and the appropriate behaviors associated with using a toilet.

Other terms such as potty training, while often used interchangeably with toilet training, can sometimes imply a more informal approach, often associated with specific methods or strategies. Self-training and behavioral training do not accurately capture the complete scope of the developmental process involved in mastering this important life skill.
