What causes slow growth and development in infants?

Infant growth and development delays may result from the combined effects of various factors. 1. Maternal factors, such as malnutrition, emotional disturbances, and diseases, may adversely affect fetal growth and development. 2. Genetic factors play an important role in infant growth and development; parental genetics may influence an infant's growth potential. 3. Feeding methods are also a key factor affecting infant growth and development. Inadequate feeding, lack of essential nutrients, and insufficient caloric intake can all lead to delayed growth and development. Additionally, gender differences may lead to variations in growth and development between boys and girls. 4. Environmental factors, such as family atmosphere, living conditions, and hygiene, may also impact infant growth and development. Parents should take all these factors into account and provide comprehensive care and support to promote their infant's healthy growth.
