You're all probably heartily sick of this subject but had to share another
reference (last one I promise!) I've found (in humans) supporting glandular
growth during established lactation:

"At 1 month lactation, the "empty" volume of over half the breasts (in the
study) was higher than that at the end of pregnancy. While small increases
in breast volume may have been caused by additional amounts of milk being
retained within the "empty" breasts, the magnitude of the larger volume
changes (93-211ml) suggests that growth of considerable amounts of breast
tissue occurred post partum."
(please don¹t jump on the term "empty" - this has been derived using
different measured variables over a 24 hour period - have to read the paper)
He also quotes Hytten (who did the first breast measurements using water
displacement in 1954) and reported the breast volume of subject 113 (who had
no breast growth during pregnancy) increased a 160% by 7 days postpartum. A
similar situation occurred with one subject in the Cox study where there was
no growth occurring until after birth.

David Cox goes on to say that growth of the mammary glands during lactation
may NOT be a rare phenomenon.

Cox, DB et al. 1999. Breast Growth and the urinary excretion of lactose
during human pregnancy and early lactation: endocrine relationships.
Experimental Physiology. 84,p421-434.
This paper is actually a very good read. Recommended.
