This literature review comprehensively examines common feeding mistakes in infants aged 0–12 months and evaluates mothers‟ knowledge, attitudes, and behaviors regarding infant nutrition. Feeding practices during the first year play a critical role in growth, development, immune system maturation, and long-term health outcomes. Reviewed studies indicate frequent early or late introduction of complementary foods, inadequate breastfeeding duration, inappropriate portion sizes and food choices, hygiene deficiencies, and other feeding mistakes. Maternal knowledge, attitudes, and behaviors are influenced by socioeconomic status, education level, and cultural factors.
