Q: My 5 months old baby boy has a head circumferance of 46 cm. His weight is 6.57 kg. Is this normal?

A:Head size of 46 cm for a 5 months old baby is a little more than normal. It is important to look at serial head measurement and also examine the baby for any other abnormality like bulging fontanelles or wide open sutures. If there is a doubt consult your pediatrician for further investigations.
