Thank you for posting your query in healthcaremagic.com and giving us this opportunity to clarify your doubts.
Well, increase in the head circumference more than normal and screeching persistent and unconsolable cry early morning are all sinister signs of hydrocephalus
(fluid in the ventricles in the brain). The other signs are projectile and forceful vomiting, bulging anterior fontanelle
(the soft tissue
on the apex of the skull-the area which is soft and not hard like the rest of the skull), and eyes looking persistently downwards. I would recommend you to see your pediatrician
or preferably a pediatric neurologist
who might do a detailed examination and a few imaging studies to help diagnose the condition.
I hope I have been able to clarify your doubts and helped you to make a decision. I will be always available in case of further doubts. Take care and stay healthy.
