Many women are under the impression that it is necessary to own
or use a pump to breastfeed. This is not so. There are very few
circumstances under which it is necessary to express your milk.
But women are being encouraged to pump their milk and give it to
baby via bottle for the most unnecessary reasons: Weddings, doctor’s
appointments, shopping…why not take the baby with you? How
can babies not be welcome at weddings? Or, “so the father
can feed the baby”! Partners were not meant to feed babies
milk, and giving a bottle is not really helping. But they certainly
can help feed the baby by helping mother with compressions,
for example, (see Handout: #15 Breast
Compressions) and they can help mothers in so many other
ways as well. The pump should not replace the baby; you and your
baby receive numerous benefits in addition to nutrition by breastfeeding.
No pump is as efficient as the natural pump that was made for
your body, your baby! A baby who breastfeeds well is the best
pump, but, granted some babies don’t breastfeed well. You
do not need a breast pump to breastfeed; uninformed use of a breast
pump can lead to premature weaning.
- There is more to breastfeeding than just the breastmilk.
- Obviously, if you can pump a lot, you are producing a lot, but
if you cannot pump a lot, this does not mean your milk production
is low. Do not pump to “find out how much you are producing”.
- The most effective artificial pumps are high-powered, double,
electric, and hospital-grade with adjustable pressure and speed.
There are many pumps on the market that are just not very good.
- Improper use of a breast pump can lead to problems. Read all
instructions thoroughly.
- It is important that milk be expressed and/or pumped after the
feed as the breasts should be as full as possible for the baby’s
feeding. Babies respond to fast flow (see Handout #15, Breast
Compression), and pumping before the feed will reduce
the amount of milk in the breast.
Pumping method
- Pump immediately after the feed--waiting an hour or so decreases
the likelihood the breast will be full as possible for the next
feed.
- Place nipple in the center of the flange (unlike nipple placement
in baby’s mouth, which should always be off-centre and pointed
toward the roof of baby’s mouth (see Handout: A: When
Latching).
- Put the pump on the lowest setting that extracts milk, not
the highest setting you can tolerate.
- Pump for 15 minutes each side. If breasts run “dry”
before 15 minutes is up, pump until dry then add 2 minutes.
- Remember, pumping should not hurt. If it hurts:
- Lower the suction setting
- Ensure the nipple is centered in the flange
- Pump for a shorter period of time
Cleaning the pump
-
All pumping equipment should be sterilized before
first usage, thereafter it only requires washing with hot, soapy,
water or by dishwasher.
- After each pumping: either place the pumping kit (not the tubes
or motor) in the refrigerator until the next pumping, or if not
pumping the same day, hot-water wash and hot-water rinse well,
then air dry.
- Remember to take apart all pieces of the pump for cleaning---including
the smallest pieces, and to ensure that no milk has clumped in
the flange shaft.
Hand expression
Many women find that hand expression is an efficient way to pump
when only occasional expression is required. In fact, when the milk
production is not abundant (as in the first few days), it is often
easier to get milk with hand expression than with a pump and many
women find this the easiest way to express mature milk as well.
- Place thumb and index finger on either side of the nipple, about
3 to 5 cm (1-2 inches) back from the nipple.
- Press gently inward toward the rib cage.
- Roll fingers together in a slight downward motion.
- Repeat all around the nipple if desired.
Breastmilk storage
Unlike formula, breast milk is anti-infective, antibacterial, antifungal,
and antiviral.
- Breastmilk will stay good:
- At room temperature for at least 8-12 hours.
- In the fridge for at least 8-11 days.
- In the freezer, at the back, for many months.
Get used to the taste and smell of breast milk so you'll always
know if it is good.
- Due to the high fat content of breastmilk, storage of any kind
will produce a separation in the liquid. This is normal; a gentle
mixing will give it a homogeneous look once more.
- Breastmilk may taste different after freezing; this is normal.
- Never heat breastmilk in the microwave.
- Babies will often take cold milk, but if heating is desired,
or if milk needs to be defrosted, place container or bag of milk
in a cup of warm water for a minute or two.
Encouraging the M.E.R. (milk ejection reflex) or “let down”
If your baby is not present, you can encourage the “let down”
reflex artificially, by having a picture of your baby to look at,
or by having a piece of his clothing next to you.
- Apply a warm wet cloth to your breasts.
- Massage the breasts in small circular motions around the perimeter
of the breast.
- Gently stroke your breasts with your fingernails in a downward
motion toward the nipple.
- Lean forward and gently shake the breasts.
- Gently roll the nipple between your finger and thumb.
You may feel the milk ejection reflex or notice your breasts leaking
or you may not. You are likely to pump more milk
faster if you pump both breasts at the same time. You do not need
to feel or be aware of the milk ejection reflex in order to make
milk. Some women may feel thirsty, sweaty, sleepy, or dizzy during
a let down. However, many women do not feel this milk ejection response
ever in their whole breastfeeding experience. Some women only become
aware of it after the first few weeks. This has absolutely no bearing
on milk supply. Breast compressions, while pumping, can be very
effective at increasing the amount expressed, it may be a bit awkward
at first, but it can be done (mothers have fixed the cups so that
they sit inside the bra and then use compressions) or the partner
can do it.
