what age is a toddler

According to most experts, toddlerhood starts at 1 year of age. The toddler age range runs from around 1 year (12 months) to around 3 years of age. The Centers for Disease Control (CDC) considers toddlers to be children between the ages of 1 and 3. Therefore, a toddler is generally considered to be a child between the ages of 1 and 3 years old. During this stage, toddlers will experience significant physical, intellectual, social, and emotional changes. They will show greater independence, begin to show defiant behavior, and recognize themselves in pictures or a mirror.
