The age that is considered a toddler is between the ages of 1 to 3 years of age.
A baby is from birth to 1 year old.
Once a baby reaches 1 year old they are considered a toddler until they turn 3 and then after 3 they are considered a little kid.
A little kid is considered from age 4 to around 8 although some people considered a little kid up to age 5 and a big kid from ages 5 to 8.
A toddler is a child approximately 12 to 36 months old, though definitions vary.
The toddler years are a time of great cognitive, emotional and social development.
The word is derived from "to toddle", which means to walk unsteadily, like a child of this age.
The toddler age group starts at one year old, and while the end of the toddler age range is a little less definitive, it's generally thought to come to close when a child turns 3.
Some age-related development periods and examples of defined intervals include: newborn (ages 0–4 weeks); infant (ages 4 weeks – 1 year); toddler (ages 12 months-36 months); preschooler (ages 3–5 years); school-aged child (ages 6–13 years); adolescent (ages 14–19).
Four age groups, including babies, young adults, middle-aged adults, and old adults, are used in the classification system.
Other words for toddler are tyke, baby, preschooler, child, yearling, tot, bambino, toddlers, baby-toddler, infant and pre-schooler.
The Center for Disease Control and Prevention defines the preschool age range as being between three and five years old.
However, there are no hard and fast rules.
Some preschools enroll children at three years old; others take children at four.
The average starting age is between three and four.
