28-month-old baby height and weight development standard

A baby's growth requires the company of his parents. Newly born babies are very small and their facial features are wrinkled. Many babies grow slowly and not noticeably. Slowly, the child will change, grow taller, and his weight will change greatly. There will definitely be a very obvious contrast and difference between a 28-month-old baby and a baby of a few months old. So, what are the height and weight development standards for a 28-month-old baby?

Weight: At 1 year old, the weight is 9-10 kg. After 1 year old, the average annual weight gain 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 content about the height and weight development standards for 28-month-old babies. I hope it will be helpful to everyone. Many 28-month-old babies are very healthy, with normal weight and height, but some children are underweight and short. This may be due to insufficient nutritional supplements. Parents can give their children some children's calcium tablets suitable for children to supplement their calcium.
