Question: Dear doctor, My son had a birthweight 3.0 kg, length of 47 cm, and head circumference of 33 cm. May I know what is the measurement in centile for the respective aspect? Thank you in advance. (Sze)
Answer: Dear Sir/Madam, Thank you for bringing up the topic of centile chart. To be able to answer your question properly, we need to know whether your son is born full term or actually a premature baby. Considering that he is born full term at 38 weeks gestation, the measurements are all taken immediately after birth, according to the latest WHO growth chart, his weight of 3.0kg falls between 25th to 50th centile, head cirmcuference of 33 cm is at 25th centile, length of 47cm is 9th centile for a full term baby.
