Toilet training, or potty training, is the process of training a young child to use the toilet for urination and defecation, though training may start with a smaller toilet bowl-shaped device (often known as a potty). Cultural factors play a large part in what age is deemed appropriate, with the expectation for being potty trained ranging from 12 months for some tribes in Africa to 36 months in the modern United States. Most children can control their bowel before their bladder, boys typically start and finish later than girls, and it usually takes longer to learn to stay dry throughout the night.
