28-month-old baby girl's height and weight standard

Our little princess is already 28 months old. She has a chubby face and is very cute. As she grows older, her curiosity is gradually increasing. She yearns for the outside world and always hopes that we can take her out for a walk. Recently, my mother took the little one to the hospital for a routine check-up. The doctor said that my little princess’ height has reached the national standard, but her weight is seriously over the standard. The doctor hopes that we can give the little one more exercise. So, do you know what the height and weight standards are for a 28-month-old girl?

Height and weight standards for 28-month-old female babies:

Weight: The weight at one year old is 9-10 kg, and after one year old the average annual increase is 2 kg. Therefore, weight (kg) = 9 + (age-1) X2 = 7 + age X2.

Height: At one year old, the height is about 75 cm. It increases by about 10 cm in the second year. At two years old, the height is about 85 cm. After the age of 2, height increases by 5 cm each year. It can be calculated according to the following formula: Height (cm) = 85 + (age-2) X5 = 75 + age X5.

Teeth: Primary teeth begin to emerge 5 to 10 months after birth. Number of teeth from 6 to 24 months = age in months - 4 (or 6). Generally, all 20 deciduous teeth will appear in 20 to 30 months. After the age of 6, permanent teeth begin to appear.

Physical Appearance and Growth:

The baby's head circumference increases by an average of 0.2 cm per month, and there is basically no measurable difference from the previous few months. The fontanelles of most babies have closed, but some babies have not yet closed. If your baby's fontanelle has not closed by the age of 2 and a half, it is recommended to see a doctor.

Most babies have grown 16 deciduous teeth, but some babies may only have about 10, and some babies have all 20. If your baby has been learning to brush his teeth by himself since he was 2 years old, he can basically brush his teeth by himself now.

The above is the relevant knowledge we have obtained from experts about the height and weight standards for 28-month-old female babies. We hope that what we know can help everyone. The baby’s health is something we are all very concerned about. The baby is already 28 months old, and his height and weight are undergoing tremendous changes. So in daily life, we must pay attention to the nutritional combination of the baby’s diet and take them to participate in sports more often, so that the baby will be healthier.
