Final answer:
The standard weights for children between 2-11 years vary and are guided by growth charts. A 2-year-old is expected to weigh between 20 and 40 pounds, or 9.1 to 18.1 kg. Weight generally aligns with factors such as height, gender, and health.
Step-by-step explanation:
The standard weights of children and infants between 2-11 years of age during winter are not fixed and can vary greatly due to individual growth patterns and genetics. However, growth charts and developmental milestones provide a range to gauge typical development. For example, a 2-year-old is expected to weigh between 20 and 40 pounds, which is approximately 9.1 to 18.1 kilograms. As children grow older, their weight range broadens, considering factors like height, gender, and overall health.
Using growth reference data from the WHO, it's understood that weight is generally proportional to height and age. For instance, the WHO indicated that at a height of 80 cm, the average weight for a girl is approximately 10.2 kg. This helps provide a guideline for tracking child development by comparing the weights of children who are of the same height and gender.
