The progressive attainments by a child of skills that involve both mental and muscular activity such as the ability of the infant to sit, crawl, walk, talk, control bladder and bowel functions and solve cognitive problems.Between 12 and 36 months, a toddler acquires autonomy, independence, control of bodily functions and refinement of motor and language skills. The child likes to explore the environment, strives for self-assertion and personal interaction with others.
Toilet training should begin between 18 and 24 months, when voluntary control of the anal and urethral sphincters is usually achieved. When the child masters some motor skills, is aware of his ability to control the body and can communicate adequately, training will not be a task. Bowel training is to be given before bladder training as the urge to empty the bowel is stronger than the urge to empty the bladder and the need is less frequent and more regular. Night time bladder control may not be achieved until the child is four or five years of age. Behaviour modifications giving rewards for achievements have been found successful with both normal and mentally retarded children.
