If you're pumping for a freezer stash or to store milk for a future separation from your baby, try pumping shortly after you finish nursing – maybe 15 to 30 minutes. That way, your body will have an hour and a half or so to replenish breast milk for your next nursing session.
The first few days: Your breast milk coming in
Around day three after your baby's birth, your breast milk 'comes in' and your breasts may start to feel noticeably firmer and fuller.
Supply-demand cycle:
Milk production is a demand-supply process. More nursing/pumping results in a greater milk supply. If you consistently decrease nursing or pumping for several days, your overall milk supply will decrease and you can expect to see a decrease in pumped amounts.
In short, you should pump until milk isn't coming out any more. Or, if you're trying to boost your supply, pump a little while longer after the milk stops flowing.
Can pumping decrease milk supply? Pumping itself does not decrease your breast milk supply. In fact, it can help boost it. But if you are having trouble with low milk supply, the first step is to check that you are using the right breast pump.
Understanding the Role of Prolactin
Interestingly, prolactin levels have a typical 24-hour cycle — just like the human body's circadian rhythm. Prolactin peaks in the early morning hours around 2-5 a.m., while the lowest prolactin levels happen in the late afternoon to early evening.
Breast Storage Capacity
The maximum volume of milk in the breasts each day can vary greatly among mothers. Two studies found a breast storage capacity range among its mothers of 74 to 606 g (2.6 to 20.5 oz.) per breast (Daly, Owens, & Hartmann, 1993; Kent et al., 2006).
“Something I recommend to moms is the 5-5-5 rule,” Pawlowski says. “Try and use milk within five hours at room temperature, five days if in the refrigerator, and five months if in the freezer.”
Reaching a Full Milk Supply
A full milk supply is 25 to 35 ounces per day. Once you've met this goal, you may find that you are able to reduce the number of times per day that you pump and still maintain your supply. You can drop out one pumping session every few days and keep an eye on your milk supply.
If you're exclusively pumping, on average, you should try maintain full milk production of about 25-35 oz. (750-1,035 mL) per 24 hours. It may take some time to achieve this target, do not worry about hitting this on day one! Babies may take more milk from the bottle than when breastfeeding.
What are the “3 Golden Hours”? The 3 Golden Hours refer to the immediate hours after a mother gives birth. It's so important that mothers are given the opportunity to be skin to skin with their babies during these 3 hours to breastfeed their baby and form that immediate bond.
The first hour after birth when a mother has uninterrupted skin-to-skin contact with her newborn is referred to as the “golden hour.” This period of time is critical for a newborn baby who spent the past nine months in a controlled environment.
You'll probably start to get somewhere between 1.5-3 ounces of breast milk out every 2-3 hours. All numbers/amounts are rough estimates and may change over the course of the day. This is totally normal as your body produces the most milk early in the morning.
Double-pumping is exactly what it sounds like: using a breast pump that allows you to express milk from both breasts at the same time.
Letting your baby sleep for longer periods during the night won't hurt your breastfeeding efforts. Your growing baby can take in more milk during the day — and that, in turn, means longer stretches of sleep at night.
Everyone's experiences of breastfeeding will vary, so there is no one single day which is the hardest. However, typically, breastfeeding is most challenging during the first week. This is because you are adjusting to life as a new mum, even if it is your second baby, or even your third or fourth.
Babies who are feeding well can take anywhere between five minutes and 40 minutes at each feed. Another guide to how well your baby is feeding is what comes out! So plenty of wet and soiled nappies are a good sign.
Many newborns breastfeed for 10 to 15 minutes on each breast, but they can also nurse for much longer, even up to an hour. Talk to your doctor or lactation consultant if your newborn is regularly nursing for longer than 50 minutes, though. This may indicate that they aren't getting enough milk.
An average feeding might last 10 to 20 minutes, but a baby can breastfeed anywhere from 5 to 45 minutes at each session. Of course, the timing truly depends on the age of the baby; newborns can cluster feed for 25-45 minutes, which is normal and expected.
Newborns may nurse for up to 20 minutes or longer on one or both breasts. As babies get older and more skilled at breastfeeding, they may take about 5–10 minutes on each side.
For people who are pumping in the early days and weeks after giving birth, it's good to know that you will likely produce only a few milliliters of colostrum during each pumping session. Once your milk comes in, it's still expected that you'll pump maybe only an ounce or so at a time.
It's important to remember that your baby is much more effective at getting milk from your breasts than a pump will ever be. A healthy, thriving baby will get more milk than you a capable of pumping.
