A toddler is a young child typically between the ages of 1 and 3 years. During this stage, children experience rapid growth and development, both physically and mentally. They begin to walk, talk, and explore their surroundings, which helps them learn about the world around them. Toddlers are known for their curiosity and energy. They often engage in play, which is essential for their social and cognitive development. Activities like building blocks, drawing, and pretend play are common as they learn to express themselves and interact with others.
