Question
The baby is three months old, and during the check-up, the anterior fontanelle is only 0.5 centimeters, the head circumference is 39 centimeters, the weight is 6 kilograms, and the height is 60 centimeters. Is this development situation normal?
Answer
A normal newborn baby is born with a head circumference of about 34 centimeters, a weight of about 3 kilograms, and a height of about 50 centimeters. By three months old, the head circumference typically increases by about 8 centimeters, the weight increases to about 6 kilograms, and the height grows by approximately 10 centimeters. According to the information you provided, the baby’s height, weight, and head circumference are all within the normal range, so there is no need to be overly concerned. It is recommended to continue with reasonable feeding, regularly conduct health checks, and pay attention to supplementing cod liver oil while ensuring the baby gets plenty of sunlight to promote calcium absorption.
