  • Remember that you may see one or two warning signs at a time. You will probably not see all the signs at any one time.
  • Call your child's doctor if you notice one or more of these signs. If your child's doctor feels this is a neurosurgical problem, please call our office at 513-636-4726 and your call will be directed to the appropriate person.
