Measurement and reference standards for height and weight of seven-month-old babies

Babies are the most beautiful and precious gifts God has given to every family. The healthy growth of babies concerns every family member. Paying attention to changes in the baby's height and weight can help you understand your child's growth and development in a timely manner, provide feedback on deficiencies in daily care, and make improvements. This is something every parent should pay attention to. So what is the reference standard for the height and weight of a seven-month-old baby? How to measure it? Let’s discuss this below.

Reference values ​​for weight and height of 7-month-old babies: Boys weigh 6.9-10.7kg and are 66.2-75.0cm tall; Girls weigh 6.3-10.2kg and are 64.0-73.5cm tall.

So how do you correctly measure and calculate your baby's height and weight?

1. Standard measurement formula for infant weight:

Weight at 1-6 months (kg) = birth weight (or 3 kg) + age in months × 0.6 (kg)

Weight from 7 to 12 months (kg) = birth weight (or 3 kg) + age in months × 0.5 (kg)

2-10 years old weight (kg) = age × 2 + 7 (or 8)

The standard growth pattern of infants' height: the average full-term baby is 50 cm long, and increases by about 25 cm in the first year after birth, so it is about 75 cm at one year old; thereafter, the average growth is about 5 cm each year, so the height of a child aged 2-12 years (cm) = age × 5 + 75 (cm). Anyone whose height exceeds the standard by 10% or is less than 10% is considered abnormal.

2. Actual method of measuring height 1. Take off the baby's shoes, hat and socks each time you test, so that the measured data will be more accurate. You can let your baby lie on the table for testing. During the test, place the table close to the wall and place a soft ruler on the outer edge of the table with the scale reading to 0.1 cm. Let the baby's head lean against the wall, with both feet flat on the ground, and then read the scale of the tape measure to 0.1 cm.

3. The actual method of measuring weight is to make the baby fast and empty his/her stomach before each test, otherwise there will be errors in the baby's net weight. In order to prevent the baby from catching a cold, the clothes and diapers can be weighed together during the test.

A seven-month-old baby's height and weight can provide timely feedback on whether the baby is receiving adequate nutrition and exercise during this developmental stage, so that parents can make corresponding adjustments in daily care. Friends who have babies at home must remember to pay attention to the baby’s height and weight in a timely manner, and adjust the baby’s diet and activity arrangements. In addition, you can also mark your baby's height and weight as a testimony to your baby's growth and a gift.
