Accepted Answer

The WHO (World Health Organization) standards for child growth are widely used to assess the growth of children, including their weight and height. These standards are based on data collected from around the world and provide guidelines for healthy growth patterns from birth to 5 years old.

The WHO weight-for-age and height-for-age charts provide expected ranges for healthy growth, but these can vary based on factors like genetics, nutrition, and overall health.

Here is a general guideline for weight based on WHO standards for babies and children:

Weight: 4 to 6 kg (8.8 to 13.2 lbs)

At 4 months:

Weight: 5.5 to 8 kg (12.1 to 17.6 lbs)

Weight: 12 to 16 kg (26.4 to 35.2 lbs) WHO Height-for-Age Standards:

At birth:

Average height: 48 to 53 cm (19 to 20.9 inches)
