Infants are very young children, typically defined as babies from birth to one year old. During this stage, they grow rapidly and develop essential skills like crawling, sitting, and eventually walking. Infants rely heavily on their caregivers for nourishment, comfort, and safety. They communicate mainly through crying and cooing, expressing their needs and feelings. As infants explore their surroundings, they begin to learn about the world around them. They are curious and often fascinated by simple objects, such as toys and colorful books. This early stage of life is crucial for brain development, laying the foundation for future learning and social interactions.
