The height and weight of a child are the most important concerns for parents, but each child's development is different, and the reference standards are also different. Many mothers feel very anxious when they find that their babies are half shorter than those from other families. In fact, expectant mothers only need to refer to the 2017 height and weight comparison table for young children, as long as the child meets their own growth pattern.
Weight Standards for Preschool Children in 2017
A normal full-term baby is born with a weight of around 2000 to 4000 grams. In the first 3 months, the baby's weight increases by 180 to 200 grams per week, 150 to 180 grams per week at 4 to 6 months, 90 to 120 grams per week at 6 to 9 months, and 60 to 90 grams per week at 9 to 12 months. According to the multiple of weight gain, a baby's weight is twice that of birth at 6 months, about 3 times at 1 year old, about 4 times at 2 years old, and about 4.6 times at 3 years old. In the second year of birth, the average weight of the baby increases by 2500 to 3000 grams. After the age of 2, the average annual growth is about 2000 grams, until the puberty period. Formula for calculating the weight of babies at different stages: weight under 6 months=birth weight+age x 600 grams; 7 to 12 months weight=birth weight+age x 500 grams; Weight from 2 to 7 years old=age x 2+8000 grams.
2017 Height Standards for Preschool Children
Body length is the sum of the lengths of fingers, torso, and lower limbs, and the ratio of the three varies at different stages of a baby's life. The average length of a baby at birth is around 50 centimeters. The body length grows the fastest in the first year, with an average monthly increase of 2.5 centimeters from 1 to 6 months, an average monthly increase of 1.5 centimeters from 7 to 12 months, and an increase of 25 centimeters from birth at the age of one, which is approximately 1.5 times that of birth. In the second year after birth, the growth rate of the baby's body length begins to slow down, only increasing by 10 to 12 centimeters throughout the year. From the age of 2 until the onset of puberty, the average length of a baby increases by 6 to 7 centimeters per year. The younger the age, the larger the ratio of head to upper body, and as age increases, the growth rate of the lower body is faster than that of the upper body. The formula for calculating the body length of babies aged 2 to 7 is age multiplied by 5 plus 75 centimeters.
