A toddler is a child between the ages of 1 and 3 years old. This is a critical period of growth and development, as toddlers undergo rapid changes in their physical, cognitive, social, and emotional development. Toddlers are often characterized by their newfound independence and curiosity, as they explore their environment and learn about the world around them. They are also known for their developing language skills, as they start to communicate more effectively and express themselves using words and gestures. Overall, the toddler stage is a critical time for laying the foundation for a child’s future growth and development.
