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 boys longer to learn to stay dry throughout the night, however it depends on the maturity and consistency of the particular child.[vague]
Most people advise that toilet training is a mutual task, requiring cooperation, agreement and understanding between the child and the caregiver, and the best potty training techniques emphasize consistency and positive reinforcement over punishment – making it enjoyable for the child. The vast majority of studies concentrate on children 18 months old and older. For that time frame, research suggests that children over 24 months train faster and girls train slightly faster than boys.
One of the ways to potty train a child is through potty training songs that make this task enjoyable for the child. There are songs that show the sequence of the steps needed from the child's perspective.
History in the United States
Until the mid-1900s, the vast majority of babies finished toilet training by 2 years, and achieved nighttime dryness by 3 years. Since then, the age for toilet training has increased dramatically. The convenience of disposable diapers, pull-up diapers and more efficient laundry facilities may contribute to this trend.
In 1957, the average age of starting toilet training was still under the age of one year old, 11 months, and 90% of children were dry during the day by 2 years.
In 2002, the average age that parents recognized their child "showing an interest in using the potty" was 24–25 months, and daytime dryness was achieved on average at almost 3 years of age. Now nighttime accidents are considered normal until 5 or 6 years of age.
