Newborn disorders are unique as they involve significant physiological changes from fetal to neonatal life, ongoing organ development, and susceptibility to uterine environmental conditions, such as intrauterine infection/inflammation. Childhood diseases impact infants to adolescents, a period marked by significant changes in both the child and their surroundings. Noticeable transformations in growth and development make children appear as distinct individuals evolving through childhood and adolescence. Environmental shifts reflect a child's move from complete dependency to increased independence, emphasizing the need to understand their health and sickness in this dynamic context.Â
