My son is almost 4 years old. At birth he was ok, as he went for his routine dr visits and vax they noticed his hard was growing very fast. At that time they suggested that we go to a neurologist and that neurologist said his ventricals were enlarged and needed surgery. we went to childrens hospital they said surgery. we went to st christophers hospital they said no. than they both agreedd to see what happens. at this time he is smart and his head is still large and he is active he is very small for his age only weighing 22 pounds at almost 4. just wanted advice if i should worry or am i being too paranoid
