Right after delivery, the baby already undergoes an evaluation with the pediatrician who closely monitors the birth with the obstetrician. The information collected is recorded in a document that will be delivered to the parents at the time of discharge, which contains information such as the weight the baby was born, height and the circumference of the head, as well as which delivery was performed. These are the first pieces of information that will be noted in the baby’s growth chart, which will accompany him at least until he reaches the age of three.
In addition to the baby’s growth chart, pediatricians use graphs with references to monitor each age group where it indicates the child’s height and height potential calculation when they reach adulthood. This table is known as a percentage graph and it shows what percentage the baby or child is in.
During the consultation with the pediatrician, the baby will be weighed and measured in order to establish the evolution and growth of the baby on the chart . This curve is performed in the standard table of the World Health Organization (WHO) which is updated to follow the physical changes of the population all over the world. Your baby’s curve should not be exactly WHO standards but close to what is considered healthy. It should only be worrying if your baby’s curve goes out too much than expected by the baby’s growth chart.

For this reason, continuous monitoring with the pediatrician to assess the baby’s development is extremely important . For moms who are in the habit of comparing the weight and height of their babies to those of those close to them, remember that each baby and child develops in their own way and has their growth different from each other, in addition to the genetics of family be different. So it’s not because your baby is thinner or smaller than the other one that is out of the ordinary !!
If there is a decrease in the curve in the baby’s growth chart, the pediatrician will analyze the feeding issues, indicating the best way to remedy the situation. Schedules of breastfeeding or the milk that is being offered to the baby, as well as when introducing new foods, everything should be informed to the pediatrician to know how the baby’s body is responding to each phase. If necessary, the pediatrician may request additional tests for more detailed verification.

My name is Dr. Alexis Hart I am 38 years old, I am the mother of 3 beautiful children! Different ages, different phases 16 years, 12 years and 7 years. In love with motherhood since always, I found it difficult to make my dreams come true, and also some more after I was already a mother.
Since I imagined myself as a mother, in my thoughts everything seemed to be much easier and simpler than it really was, I expected to get pregnant as soon as I wished, but it wasn’t that simple. The first pregnancy was smooth, but my daughter’s birth was very troubled. Joana was born in 2002 with a weight of 2930kg and 45cm, from a very peaceful cesarean delivery but she had already been born with congenital pneumonia due to a broken bag not treated with antibiotics even before delivery.
