Aww … how precious … it's a baby. A new life has just emerged and it begins its evolution into an adult. When the infantile creature is born no one deems to sit there and measure its height for every single month in order to see the progress the baby makes. The only real time the baby is weighed and measured in length is when it's just born and these numbers are recorded on its birth certificate in the United States and other places in the world but not everywhere.
Each individual baby has its own marked height and weight as well as appearance. But to this day there are statistics that provide an average height. According to the National Center for Health Statistics, the average height of a newborn baby boy is in the range from 45-55 cm and the median height is 50 cm. For a delicate newborn baby girl, the numbers are quite less: it's from 45-54 cm and the median height is 47 cm. To one it might not seem a big difference but in reality a centimeter or two means a great deal to a parent.
