Step-by-step explanation:
Toilet training is typically mastered around the age of 18-24 months. By this age, most children have adequate physiological, neuromuscular, and psychological maturity to learn and achieve toilet training.
According to developmental milestones, by age four, most children can run, climb stairs, and scribble with crayons. They have acquired many words and use simple sentences, and the majority are also toilet trained.
Furthermore, at the age of three, toddlers show preferences for toys or foods and can play games with simple rules. They are well on their way to achieving toilet training, as they can anticipate routines and are more self-aware of their physiological and neuromuscular functions.
