At what age do most children start toilet training?

Most children typically begin toilet training between the ages of 2 to 3 years old. This developmental milestone aligns with their physical, cognitive, and emotional readiness to transition from diapers to using the toilet. At this age, many children start to show signs of readiness, such as staying dry for longer periods, showing interest in the bathroom habits of adults or older siblings, and being able to communicate their needs.

Toilet training is influenced by various factors including the child's maturity, motor skills, and the parents’ or caregivers’ approach to the training process. Beginning the process too early, such as at 1 year old, might result in challenges, as many children at that age are not developmentally ready. Conversely, waiting until ages 3 to 4 years or 4 to 5 years can lead to prolonged dependency on diapers and potential delays in achieving this necessary skill. Therefore, the age range of 2 to 3 years is generally considered optimal for starting toilet training as it coincides with the child’s developmental growth in various areas.
