Year 1 is the second year of a child's life, following their first birthday. During this time, children typically develop important skills such as walking, talking, and social interaction. They begin to explore their environment more actively and may start to show preferences for certain toys or activities. In Year 1, children often experience significant growth in their cognitive abilities. They may begin to understand simple instructions and can recognize familiar faces and objects. This period is crucial for language development, as they start to form basic sentences and expand their vocabulary, laying the foundation for future communication skills.
