A pre-school child, or preschooler, is one below primary school age, typically in the age range of about 3 to 5 years (the definition of school age varies among countries). A pre-school child is between toddler and school age and may attend preschool (or kindergarten in countries where the term kindergarten refers to pre-school education).
At this age parents often decide the child is old enough to start being held accountable for their behaviour and add punishments into the discipline program. At this foundational lesson level they are frequently in trouble. So parents tend to favor quick punishments—such as spanking or corner time—so the forgiveness can follow as quickly.
