I have to preface this with the admission that I'm not actually Paleo, BUT, I'm a big fan and student of Paleo and hope to be Paleo some day. Anyway, I've been BF and/or Pregnant (non-stop) since 2005 (three kids), and I'm a total Lactivist.
The good news is that your baby's growth spurts will get fewer and farther in-between now that you've hit 6-months, and whether you're doing BLW (baby led weaning) or standard American baby feeding or something else, your baby will start filling the holes in his diet with food other than breastmilk.
Not sure how this might fit into what you are looking for, but if you had Pitocin during/after labor (which you did (whether you know it or not)because it's standard, unless you demanded that they not give you the shot between delivery of baby and delivery of placenta), but there's a theory out there that Pitocin causes women to hang onto bodyfat instead of shedding it like nature intended. Here's the best summary I've been able to find, from the Facebook Site of Intuitive Parenting Network, LLC:
Another myth--that moms need to eat
more calories while breastfeeding: It
is true that we require more
nutrients, but not that we need to eat
more calories to get them.
Historically, there would not be more
food available just bc women gave
birth. Nature is far more efficient
and solved the problem another way.
During pregnancy and the early pp
period, the villi expand by approx 25%
to increase their efficacy in nutrient
absorption. That expansion is
triggered in part by an increase in
oxyctocin receptors in the gut.
The problem comes in of course, when
you already have an damaged gut, as so
many Western women do (which means you
are already deficient in many
nutrients), when you have a
medicalized birth, especially which
involves pitocin. An assault of
synthetic oxytocin causes receptor
sites to shut down. The least
necessary will shut down first--such
as those in the gut. With almost
every woman in the West today
receiving pit after birth, we have
created a cascade of damage that we
are only beginning to even recognize.
From Marshall Klaus: "Five of these
hormones stimulate the growth of
intestinal villi in the mother and the
infant. As a result, with each
feeding, there is an increased
intestinal surface area for nutrient
absorption. The hormonal release is
stimulated by the touch of the
mother's nipple by her infant's lips.
This increases oxytocin in both the
mother's brain and the infant's brain,
which stimulates the vagus nerve, then
causes the increase in the output of
gastrointestinal hormones. Before the
development of modern agriculture and
grain storage 10 000 years ago, these
responses in the infant and mother
were essential for survival when
famine was common.10"
