What is the standard for growth and development of a 13-month-old baby?

The growth and development standards for a 13-month-old baby mainly include aspects such as height, weight, and language ability. In terms of height, the average height for male infants is about 76 to 83 centimeters, while for female infants it is approximately 74.9 to 81.5 centimeters. Regarding weight, male infants typically weigh between 9.89 to 12.6 kilograms, and female infants usually weigh between 9.16 to 11.8 kilograms. Additionally, in terms of language skills, a 13-month-old baby can understand simple instructions and can produce some simple single words or two-syllable words. At the same time, the baby's walking ability develops rapidly, with most babies able to attempt standing, walking, or even running, and can stand independently for a period of time from a sofa or other supporting object. These standards are only general references, as each baby may develop at a slightly different pace. Parents should evaluate their child's development based on their individual circumstances to determine if it is normal.
