There are different reasons why a baby comes into the world earlier than expected. This is the premature or pre-term baby, who is born before 37 weeks of gestation. This anticipation demands some extra care to accompany their development in the best way, considering not only their chronological age, but also their corrected age.

Does this mean writing down two dates? Exactly! You see, during the entire gestation, including the final weeks, the baby undergoes an important development. Thus, if he is born prematurely, attention to this aspect becomes fundamental.

In this article, we will clarify what the corrected age is, how to make this calculation and up to what point to consider it to observe the development of your child. Read on!

What is a fixed age?

The corrected age is calculated in cases of prematurity, which is the birth before the 37th week of gestation. It is an account that considers the baby’s age if he or she had been born at term.

Thus, the family and paediatrician’s view of the baby’s development is turned to the corrected age and not to the chronological age. Thus, if the baby is born one month earlier than expected (40 weeks), one month should be added to the chronological age to obtain the corrected age.

In this way, in order to know, for example, if the baby has the expected weight and height, the paediatrician uses the corrected age as a parameter.

How do you calculate the corrected age?

The corrected age is the chronological age minus the weeks missing to complete the 40 weeks of pregnancy. It is simple to calculate: if you were born at 32 weeks of gestation, your baby was considered 8 weeks or 2 months premature.

So if he is now 5 months old (20 weeks since birth), the corrected age is 3 months. In this example, it is necessary to follow your baby’s growth and development taking into account that he is 3 months, not 5 months.

In fact, understanding this is important so as not to create unrealistic expectations regarding your child’s development based on their chronological age. If you have any doubts, do not hesitate to talk to your pediatrician.

Until when to consider it in the baby’s development?

For how long will you and your pediatrician base your assessment of your little one on the corrected age? The ideal is to have this parameter until at least two years of age. With this, it is possible to follow the milestones of child development in a more precise way.

The corrected age is used when a baby is born prematurely, so that it is possible to follow the skills that he or she is acquiring in each phase without it meaning a delay in development (if only the chronological age were considered).
