Sorry - a colleague of mine told me that it would be higher percentage than that with twins as the infants would probably have a lower birth-weight which would put them at a considerable disadvantage to a normal birth-weight child. Jill, you did not say when/where these babies were born, but new-borns are bigger these days - thanks to better nutrition of pregnant mums. These days we would say "inability to thrive" about poor sickly infants. Although twins do thrive now because we compensate nutritionally etc when needed. It must have been awful for the parents to lose 4 of their babies like that. And hard to imagine their sorrow. I think you have started an interesting discussion cathy
