Mary,
I haven't seen this research yet, but how can some of the children have
been 'exclusively' breastfed if they all received some formula, even if
only during the first few days?  Also I bet it does not mention the
adverse effect on the establishing milk supply! No doubt this study will
now be endlessly quoted to show that formula does no harm.
