Growth percentiles from 0 to 2 years: what they are and what they are for

What are growth percentiles and what are they really good for? Learn what it is, why it is important, and what the 0-2 year percentile tables are.

Surely if you are pregnant right now, as if you are even about to give birth, it is more than likely that at some point you have wondered about  what the growth percentiles are, so important in the different periodic reviews that the pediatrician will perform your future baby.

Growth percentiles are basically growth charts that include measurement charts to compare and assess your child’s growth, compared to a range used as a standard.

With this, pediatricians document the development and growth of babies and children based on their age, from the time the child is a newborn to reaching 18 years of age.

They are important tables, since they provide us with information about the size and growth of the child, being able to serve as a warning against the possible existence of a medical problem that the child may have.

Therefore, it is vital –as well as important- that parents comply with the different medical check-ups indicated by their pediatrician.

They provide really valuable information both to the pediatrician and to the parents themselves, since they help to compare – with a standard range – and to assess the growth and development of our children from birth to 18 years of age.

In addition to the growth percentiles themselves, there are also growth charts prepared by the World Health Organization (WHO) with the height and weight curves that the smallest should have as they grow.

Regarding the growth percentiles from 0 to 2 years, it tends to be very common for the first year of life to grow by the percentile it had at the time of birth, although it is normal for those little ones born with a tall stature to usually they also grow by the highest percentiles (while those born smaller also grow by lower percentiles).

It is also common for those babies who have had certain problems during pregnancy to be somewhat smaller at birth than they should be, the opposite happening when the pregnancy is very favorable.

What are growth percentiles for?

Taking into account that growth percentiles  are growth tables that include measurement tables with a standard range to compare and assess the growth of the smallest from birth (basically from when they are newborns) until they are 18 years old, There is no doubt that we are faced with an extremely valuable medical element for the pediatrician.

Why? Mainly because with these percentiles, and with the periodic review of the child, pediatricians document the development and growth of babies and children based on their age.

Hence, it is essential that parents comply with the different periodic check-ups marked for both the baby and their children when they are somewhat older, since the growth percentiles provide valuable information on their development and growth, always compared to the growth percentiles according to their age and gender.

For example, during the first 18 months of a child’s life, slow brain growth could indicate the existence of brain malformations, while an abnormal growth of the head circumference could indicate a disorder or the presence of hydrocephalus.
