[|Human|] Hi Doctor,I have 9 and half month old baby girl. Her wight is 8.7 Kg, length 71 cm and head circumference is 46.5 cm. doctor said me that the head circumference is little bit more than average. could you please suggest me what i should do.Regards,Fahim
[|AI|]  Hello the head circumference(HC) of your baby should have increased by 10-11 CMS from birth. Check the birth card for head circumference and add 11 CMS to it if it comes 0.5cms plus or minus 46.5 cm, then the HC is within normal range, and you should not worry. Generally babies are born with HC of 35-36 CMS, in that case as you can calculate its in normal range. But if you are suspecting enlarging head measure HC monthly, it should not increase more than 0.5 cm monthly.
