 Process for Seeking Consent Initial screening for patients that meet the criteria will be done by the Developmental Pediatricians at the Child Development Clinic. When patients are in the SSCY Centre for a counsel with their Pediatrician, the Pediatrician will provide the families of all those who meet the inclusion criteria with a study advertisement containing the PIs contact information. Parents who phone the Principal Investigator to find out more about their participation in the study will be given the option of meeting the Principal Investigator at an office in the SSCY Centre or at their home, or at a place of their choosing. The Principal Investigator will explain the study and the consent form at that time. Parents will be told that they do not need to decide immediately and that they have the option of reviewing the study documentation and consent forms with others, and at their convenience. They will also be given a phone number to call if they have any further questions.
