Pat,

Good point:
<One question that comes to my mind is: how do we really know what
prolactin
levels would be in a woman who is fully BF, ad lib at 4-6 mo, before
solids
are added.  I'd bet a nickle tests weren't originally  done on fully BF
women ! By 120 days many women were probably "weaning". >

Nor do we know whether they were drawn in early a.m. or afternoon, with
the mom fasting, or recently having eaten, or at what time period after
the previous nursing. Lots of variables, as I quoted from the reference I
posted about prolactin earlier this week.
