My 2 year old DS head looks unusual, everyone seems to comment on it. I have brought this up with doctors/HV several times. His head is very big at the back like a lightbult rather that flatish or graduated. HV/doctors have said that it is on the scale of normal and as he has normal development they will not look into it. His top soft spot did not close until 18mths and he has a ridge where the bones overlap. Should I just leave it ot take him back to the doctors?
