[|AI|]  Hi, I had gone through your question and understand your concernsAverage head circumference of a 9.5 month baby is 44-45 cm. If everything is normal , means physical examination and development normal, it does not seem to be reason of big concern. Ultrasonography of brain (if anterior fontanelle is open), can be done to rule out HY Chat Doctor. Most common cause of large head in a normal child is familial, (feature present in other family members) or Idiopathic and also in big baby. You can discuss doing an ultrasonography of brain with your doctor, if he/she considers it to be done, it can be done to be sure that we are not missing anything. Keep a watch on development of your child. Hope this answers your question. If you have additional questions then please do not hesitate in writing to us. Wishing your baby good health.
