Nothing in this quote you've plagiarized refutes what I said. Gestational age measures the length of the PREGNANCY, not the age of the fetus. It's not my fault you don't understand English very well.<quoted text>
After birth, gestational age can be measured by looking at the baby's weight, length, head circumference, vital signs, reflexes, muscle tone, posture, and condition of the skin and hair. The baby's developmental gestational age on the day you were born may not be the same as the baby's calendar age on the day you were born. For example, an infant born at 36 weeks may actually have a developmental gestational age of 38 weeks.
Why is it important to determine gestational age on the day you were born? It helps the obstetricians and neonatologists anticipate what complications an infant might be expected to have. This can help them anticipate the infant's needs.
On the day you were born, your age was 0, not 36 weeks.
