Baby's height and weight are different in each age group and will change. Only when the baby can grow up healthily, will their height and weight be within the normal range. However, some parents do not know what the normal value is, so what is the standard value for baby's height and weight?
A healthy baby born at one month usually weighs between 2.5-4 kilograms. At 1-6 months, the baby's weight is usually (birth weight+age x 0.71) kilograms. At 7-12 months, the baby's weight is usually (birth weight+age x 0.5) kilograms. At 2-10 years old, the baby's weight is usually around (age x 2+7) kilograms. As long as the baby's weight is not less than or higher than 10% of the standard weight, it can be considered normal.
In terms of baby height, if it is a healthy one month old child, the birth height is generally around 50 centimeters. The baby's growth rate is relatively fast in the first year, usually at a rate of 25 centimeters. Therefore, when the baby is one year old, the height should be around 75 centimeters. After one year old, the baby usually grows at a rate of 5 centimeters per year. Therefore, during the period of 2-10 years old, the formula (age x5+75) can be used to calculate the baby's height. Like weight, as long as the baby's height is not less than or higher than 10% of the standard height, it can be considered normal.
