As far as I know, normal range for prolactin level in a lactating woman is
50-150, so 109 would be good.  I rarely check prolactin levels, unless I
suspect Sheehan's Syndrome (pituitary infarction due to massive
post-partum hemorrhage).  In that case, prolactin level would be close to
zero, even if mom were nursing 'round the clock.
