Dr. John Murphy:

I do not know. It is hard because the figures come from varied sources. Someone made the point that cases involving babies who have had a physical malformation are more clear-cut because they occur earlier on and perhaps come to greater attention because the baby is in the hospital setting and the specialists all see the child. That is far more likely to be processed and documented. Let us suppose a child goes home and seems to be okay and is out in the community. Then let us suppose something is picked up by the public health nurse, for example, something not progressing satisfactorily for a toddler. Alternatively, something may be picked up by school teachers if a child is not doing well and needs a special needs assistant. That is some years down the road. How does that come to the surface? That may be among the challenges we are faced with. Obviously, others have opinions but I am suggesting a pathway to approach it.
