Milk production is a demand and supply process. As milk is removed from your breasts, your body is signalled to make more milk. The more frequently and thoroughly the breasts are emptied (though breasts are never truly 'emptied'), the faster they try to refill.
There are two main reasons that pumping can take a long time. For some people, it can be difficult to trigger the letdown reflex, which releases the milk from your breasts. Others may be able to get a letdown, but then find that they have slow milk flow when pumping.
Signs Milk Is Coming In
Many women, even first-time moms, know exactly when their breast milk has come in, mainly due to common indicators like: Breast engorgement, or the feeling of fullness, heaviness, and/or firmness. Swelling of the breasts. Breast milk leakage, particularly overnight.
Refill Pain
Some moms describe a deep ache or dull throbbing pain after they complete a feeding. This feeling can start 10-20 minutes after the feeding is over and usually lasts 10 minutes or less. The ache is from the filling up of the alveoli with blood and lymph fluid in preparation for the next feeding.
Increasing your milk supply will take time, so don't give up. Even dry pumps (when you pump but nothing comes out) sends a signal to your body that more milk is needed on tap, so it's getting the work done even if there's no output to show for it right away. Stick with it and you'll see the results after a few days.
It may only take your baby about 5 to 10 minutes to empty each breast and get all the milk they need; however, this is different for everyone.
Drink more water. Breastmilk includes lots of water, so it can be a struggle to increase your breast milk production if you aren't well hydrated. In addition to drinking regular water, you may want to consider some lactation tea.
The fastest way to increase your milk supply is to ask your body to make more milk. Whether that means nursing more often with your baby or pumping – increased breast stimulation will let your body know you need it to start making more milk. It usually takes about 3-5 days before you see an increase in your supply.
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).
Despite views to the contrary, breasts are never truly empty. Milk is actually produced nonstop—before, during, and after feedings—so there's no need to wait between feedings for your breasts to refill. In fact, a long gap between feedings actually signals your breasts to make less, not more, milk.
As babies get more experience breastfeeding, they become more efficient and take less time to eat. Older babies may take five to 10 minutes, or less, on each side. Short nursing sessions are normal – and perfectly fine unless your baby is having trouble gaining weight.
If your baby is healthy, gaining weight, and seems content after most breastfeeds, they're getting what they need. 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!
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.
Between lack of sleep and adjusting to the baby's schedule, rising levels of certain hormones such as cortisol can dramatically reduce your milk supply.”
Avoid going longer than 5-6 hours without pumping during the first few months. When pumping during the night, milk yield tends to be better if you pump when you naturally wake (to go to the bathroom or because your breasts are uncomfortably full) than if you set an alarm to wake for pumping.
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.
As your milk supply increases, your breasts should feel heavier and full. This normal fullness should not prevent your baby from being able to latch on easily. Your breasts should also be pain-free. Engorged breasts are very hard, and the nipples can flatten due to swelling inside the breasts.
Offer both breasts then provide supplemental breastmilk or formula in a bottle once your breasts are drained. You can also try supplementing a small amount of breastmilk or formula first and then put baby to breast for the rest of the feed.
Your breasts will feel softer and less full as your milk supply adjusts to your baby's needs. This does not mean you have low supply. If your baby nurses for shorter periods of time, such as only 5 minutes on each breast.
