 After the baby is born, at 3 months of age, the patients will be contacted by phone by one of the investigators at Beth Israel Deaconess Medical Center to see if they want to enroll their baby in the neonatal follow-up portion of the study. This involves cognitive and motor testing of the child at Bostons Childrens Hospital at age 6 months, 1 year, 2 years and 3 years of age. If a head MR or head ultrasound has not been obtained for clinical indications, it will be offered to the patient at that time.
