{"abstract":"The early stages of a child's life are characterized by significant growth and development that spans across various domains. These formative years serve as a crucial foundation for a child's future learning trajectory and overall well-being. To ensure optimal development, it's essential for educators, caregivers, and parents to have a comprehensive understanding of the intricacies of early childhood development. This chapter delves into the multifaceted aspects of development that children undergo from infancy to the preschool years. It emphasizes the importance of recognizing individual differences and the pivotal role that early experiences play in shaping a child's growth and development.","abstract_source":"original","authors":["Anna Liza Magbanua"],"date":"2023-10-13","doi":"10.5281/zenodo.8437181","id":2112,"issue":4,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"c74fd6d1b385b8fe32cdcc6e3e7a4ce4dedc8a78b3b7dbf19b242e55a0271e0f","schema":"scimatic-article/1","title":"Nurturing Young Minds: Effective Strategies for Early Childhood Education","volume":14}
