How Breast Milk Is Made

      If you’ve every been pregnant or if you are pregnant 
now, you’ve probably noticed a metamorphosis in your 
bra cups. The physical changes (tender, swollen 
breasts) may be one of the earliest clues that you 
have conceived. Many experts believe that the color 
change in the areola may also be helpful when it 
comes to breast milk feeding.

What’s going on

     Perhaps what’s even more remarkable than visible 
changes is the extensive changes that are taking 
place inside your breasts. The developing 
placenta stimulates the release of estrogen and 
progesterone, which will in turn stimulate the 
complex biological system that helps to make lactation 
possible.

   Before you get pregnant, a combination of supportive 
tissue, milk glands, and fat make up the larger                                                                                             portions of your breasts. The fact is, your newly 
swollen breasts have been preparing for your 
pregnancy since you were in your mother’s womb! 
When you were born, your main milk ducts had already 
formed. Your mammary glands stayed quiet until 
you reached puberty, when a flood of the female 
hormone estrogen caused them to grow and also to 
swell. During pregnancy, those glands will kick 
into high gear.

      Before your baby arrives, glandular tissue has 
replaced a majority of the fat cells and accounts 
for your bigger than before breasts. Each breast 
may actually get as much as 1 1/2 pounds heavier 
than before!

   Nestled among the fatty cells and glandular tissue 
is an intricate network of channels or canals known 
as milk ducts. The pregnancy hormones will 
cause these ducts to increase in both number and 
size, with the ducts branching off into smaller 
canals near the chest wall known as ducts.

       At the end of each duct is a cluster of smaller 
 sacs known as alveoli. The cluster of alveoli is 
known as a lobe, while a cluster of lobes is 
known as a lobe. Each breast will contain around 
15 – 20 lobes, with one milk duct for every lobe.

     The milk is produced inside the alveoli, which 
was surrounded by tiny muscles that squeeze the 
glands and help to push the milk out into the 
ducts. Those ducts will lead to a bigger 
duct that widens into a milk pool directly below 
the areola.

     The milk pools will act as reservoirs that hold the 
milk until your baby sucks it through the tiny 
openings in your nipples.

   Mother Nature is so smart that your milk duct 
system will become fully developed around the time 
of your second trimester, so you can properly 
breastfeed your baby even if he or she arrives 
earlier than you are anticipating.

    Breast milk feeding does help with nutrients and the support of brain growth,                                                    which is something every mother should think about.
      The benefits for the nursing mom are just as 
good as they are for the baby. The hormones that 
are released during breast milk feeding will curb 
blood loss post delivery and help to shrink the 
uterus back to normal size.

    Long term, the breast milk feeding mom will have a 
lower risk for premenopausal breast cancer, 
which is the kind that strikes before the age 
of 50. The benefits will begin to show with 
three to six months of breast milk feeding and increase 
the longer that  breast milk feeding continues.

    By now, you should realize that breast milk is 
one power packed liquid. It offers more for your 
baby than formula, or any other scientific                                                                                                      creation for that matter. As you begin to plan 
for the future of your baby, make a commitment 
to breast milk feeding him for as long as you possibly 
can – as it will do both your bodies good.
