Patient's question:
My child is 3 months old this year and always feels shorter than other children's. I have been giving them calcium supplements, but I don't understand. What are the developmental standards and manifestations for 3-month-old infants?Doctor's answer:
Infancy is a critical period for children's growth and development. Weight and height are the most reflective indicators of a child's growth and development. Generally, the average height of a 3-month-old girl is around 58.5-63.7 centimeters, and the weight is around 5.0-6.9 kilograms. If a child's height and weight are below average, there may be developmental abnormalities caused by malnutrition. It is necessary to check blood tests, liver function, and the secretion of growth hormone and thyroid hormone to identify the cause of slow growth. Nutritional supplementation should be strengthened.
