How to make your milk come in faster

Breastfeeding: Tips to Increase Your Milk Supply l University Hospitals l Northeast Ohio

Signs That a Breastfed Baby Is Being Well Nourished

• Your baby nurses at least 8 to 16 times in 24 hours, or every 2 to 3 hours. Your baby may be fussy once or twice a day. At these times, he or she wants to nurse often for several hours before seeming full. This is called cluster feeding.
• Your baby wets at least 6 cloth or 5 disposable diapers and has at least 1 bowel movement in 24 hours. This occurs by 1 week of age.
• You can hear your baby swallow milk while nursing or you can feel your baby swallow when lightly touching his or her throat.
• Your breasts seem softer after nursing.
• Your baby gains 4 to 8 ounces a week after the first week. There is no need to weigh your baby at home. Your baby’s doctor will do this for you. You may notice that your baby has outgrown his or her clothing.
• Your baby has regained his/her birthweight by 10 to 14 days after birth.

Factors Which Can Cause Your Milk Supply to Decrease

• Your baby feeds fewer than 8 to 16 times in 24 hours. Milk production is affected by how well the breast is drained.
• Your baby has a very weak suck, or has an improper latch.
• Giving bottles of formula or water after nursing. Most babies will suck on a bottle after nursing. This just means they need to suck. It does not mean they are still hungry. Babies cry or fuss for many reasons, such as being tired, bored, wet, hot or cold.
• Giving solid foods too early and/or before you breastfeed. Most babies do not need solid foods for the first 6 months if they are breastfeeding 8 to 16 times a day.
• Smoking can cause a decreased milk supply and interfere with the letdown reflex. Here are some things you should do:
  • Try to quit or cut down.
  • Smoke after nursing, not before.
  • Don’t smoke in the same room with your baby.
• Beginning birth control pills too soon can decrease your milk supply. Wait at least 6 weeks before taking birth control pills and then use only the mini-pill (Progestin). If you still notice a decrease in your milk supply, talk to your doctor about other birth control options. Other medications may also affect milk supply. Check with your doctor. (Refer to PI-682, Breastfeeding and Birth Control: You Have Options.)
• Mothers who are exhausted may notice a decrease in milk supply. To keep yourself from getting too tired:
  • Sleep or relax when your baby sleeps.
  • Eat balanced diet that includes high-protein food.
  • Drink when you are thirsty so that your urine is pale yellow in color. Both under and excessive over hydration can decrease milk supply.
  • Take an iron supplement if your healthcare provider says you are anemic.
  • Talk with your doctor or nurse midwife about the need for vitamin supplement.
  • Accept help when it is offered.
• Use nipple shields and pacifiers with caution.
• A breast flange that is too small or too large in size can hurt your milk supply.
• Pregnancy
• Breast reduction surgery may reduce milk supply.

If You Notice Your Milk Supply Is Low

You can increase your milk supply by:

• Nursing your baby often. Nurse every 2 hours during the day and every 3 to 4 hours at night (at least 8 to 16 times in 24 hours). If your baby will not nurse, use a good quality double electric breast pump to increase milk production. Pumping after breastfeeding signals your body to produce more milk.
• Nurse your baby at least 15 minutes at each breast. Do not limit nursing time. If your baby falls asleep after one breast, wake him or her and offer the second breast. A few babies may benefit from nursing at one breast per feeding to increase the fat content of the feeding. Switch nursing- switching breasts several times during a feeding has been shown to increase milk supply.
• Gently massage breast before and during feedings.
• Use relaxation techniques to reduce stress and promote the flow of breast milk.
• Provide skin to skin time with your baby for about 20 minutes after feeds. This “kangaroo care” has been shown to increase milk supply.
• Be sure baby is positioned and latched correctly.
• Offer both breasts at each feeding.
• Try breast compression during the feeding to help drain the breast.
• Pump immediately after breastfeeding during the day. Rest at night. Some mothers find that they get more milk if they pump for 5 minutes, rest for 5 minutes, and pump for another 10 minutes.

Talk to your doctor about using medication or the herb fenugreek.

13 Ways To Help Milk Come In Faster After Birth — Milkology®

The first few days postpartum are SO overwhelming (and sometimes scary!) 

You’re in charge of a new little human that you only just met, you’re surviving on little-to-no sleep, and you’re waiting (not so patiently) for your milk to come in.

Your milk “coming in” is actually not a great term, because (to get technical) you’ve actually been producing milk since the 2nd trimester of pregnancy! 

Remember: you’ve got colostrum ready to go.

It’s just that colostrum comes out slowly and in small amounts.  But you’ve gotta trust your body… your baby’s tummy is tiny and the colostrum is specifically made by your body to be the perfect food for newborns to tie them over until your milk transitions. 

Your milk “coming in” is actually when colostrum transitions from a thicker, yellow fluid to a more voluminous, whiter, “mature” milk.

MOST women’s breast milk will transition from colostrum to mature milk about 2-5 days after birth.  For some women, it can take even longer. 

You might be thinking… “Is there anything I can DO to speed up the process?!”

Yes… yes, there is! Here are a few helpful tips on how to make your milk come in faster…

 (this post may contain affiliate links)

1. Try to take advantage of the golden hour.

The golden hour is the first hour after birth when your baby is awake, alert, and usually ready to latch. If possible, try to latch your baby as soon as possible. 

Even if you’ve had a c-section, you can request to breastfeed in the recovery room. Babies usually get tired a couple hours after birth… so attempting to breastfeed early on is a great idea!   

Your baby CRAVES to be skin to skin with you and absolutely looooves it!  It’s the most natural place for them to be and most closely mimics what it was like in the womb.  (warm, comfy, hearing your heartbeat)  

Skin-to-skin enables your baby to breastfeed more often because they’re close to the breast and can smell your milk.  Plus, skin-to-skin boosts the milk-making hormones and reduces newborn crying. 

The more you can be skin-to-skin with your baby after birth, the better!  It speeds up your milk to come in because you’ll naturally breastfeed more often. (the key to speeding up the process!)

Rooming in the same room with your baby in the hospital will ensure you’re breastfeeding on demand through the day, and night, and so you never miss a moment to respond to their hunger cues.  Speaking of hunger cues… 

4.

Breastfeed on demand and respond to your baby’s hunger cues before they get too fussy. 

Don’t worry about breastfeeding too much. (that’s not a thing!)  Remember this: you can’t overfeed a breastfed baby, but you can UNDERFEED them.

A baby that nurses frequently will often bring in mom’s milk faster.  The more you breastfeed, the more your breasts will produce… simple supply and demand! 

Your newborn will need to feed every 2-3 hours around the clock… this translates to about 8-12 nursing sessions every 24 hours.   And breastfeed every time they display a hunger cue… even if you just nursed them an hour ago!

If you and the baby are separated or baby isn’t latching well, you can hand express or pump to stimulate the breasts, get colostrum out, and help milk to come in.  (note: hand expressing is more effective for colostrum removal than pumping)  Learn it!

The more milk you remove, the more milk you’ll make.  Hand expressing your colostrum can help speed up your milk coming in.  And whatever colostrum you get out you can feed to your baby with a syringe.

Video on how to hand express

You can incorporate breast massage and compressions while your newborn is nursing to ensure you get a lot of colostrum out. 

Or you can use THIS handy little tool which uses vibration to encourage milk removal.

Like we said earlier, babies usually get sleep a couple hours after birth.   But it seems like on day 2 (curing the night specifically), babies usually WAKE UP and the only thing that makes them happy is breastfeeding and cluster feeding.  This is normal, and expected.  Your baby will want to be nursing a ton and that’s actually a good thing!  It’ll help signal your body to ramp up milk production and help your colostrum transition to mature milk faster.  Days 3 and 4 postpartum might be a fussy time for them too.  Put them to the breast whenever they display a hunger cue.  Just keep feeding, your mature milk is on the way!

If your baby is sleeping through nursing sessions, you may need to wake them up. (especially if you had a medicated birth)  You never want a newborn to go more than 3 hours without a feeding.

10. Stay Hydrated

While drinking extra fluids won’t increase your milk supply, being hydrated WILL decrease it.  So you want to make sure you stay hydrated.  Keep a water bottle nearby and drink whenever you think of it. 

My midwife actually recommended drinking THIS after birth because it helps replace lost electrolytes during delivery.

Did you know breastfeeding moms require an extra 500 calories per day?  Making milk is hard work! 

Make sure you don’t deprive yourself, especially as you’re recovering from birth.  Eat a well-rounded diet and focus on fresh fruits, vegetables, and whole grains. 

Also, a lactation cookie can’t hurt! 

Lactation cookies contain galactagogues (foods that help milk supply).  One of my favorite tips for pregnant mamas is to make and freeze some lactation cookies for postpartum.  I encourage moms to bring some with them to the delivery room.  Lactation cookies a great way to ensure you’re getting that extra 500 calories in a  day and they’re easy to eat, one-handed snacks!  

This is my favorite way to make lactation cookies ahead of time because you simply add butter, 2 eggs, and then bake!…

12. Avoid Pacifiers 

Although you might choose to use a pacifier later on, try to delay giving it to baby until you’re milk is well-established (about 4 weeks postpartum). 

Your baby has a natural desire to suck and any suckling they do away from the breast is a missed chance for breast stimulation (and bringing your milk in faster!). 

IBCLCs (International Board Certified Lactation Consultants) are the best of the best for troubleshooting and support. 

Most hospitals have them on staff so ask to see one when you’re in the recovery room.  Ask them any questions you have and be sure to have them observe you and your baby breastfeeding to make sure baby is breastfeeding well

After birth, when the placenta separates from the uterus, there will be a sharp drop in the hormone progesterone. This triggers the breast to ramp up milk production.  

So no matter if you have a vaginal birth or a tummy birth (c-section), rest assured your milk WILL come in!  (it’s just a matter of when)

• A lot of bleeding after birth

• Infection or illness with fever

• Previous breast surgery

• Strict or prolonged bed rest during pregnancy

• Having a c-section or a traumatic birth experience like a long labor or a lot of interventions

• Being a first time mom.  Studies show 1st time moms often have a slight delay in milk production.

• Certain medical conditions (diabetes, thyroid conditions, pre-eclampsia)

• Stress

• A high BMI (above 26-30) 

• Having any retained placenta fragments (your progesterone levels won’t drop to trigger milk production)

• Being separated from baby or baby having a poor start to breastfeeding (remember: the more milk you remove, the more milk you’ll make… so you’ll need to get hand expressing or pumping to stimulate your breasts as soon as possible)

Try not to stress!  Continue to breastfeed/hand express/pump as necessary and keep removing milk.   Reach out to your healthcare provider if you have any concerns or if your baby isn’t having enough wet/dirty diapers.

Breast milk production | Baby's needs

Did you know that the amount of breast milk adapts to your baby's needs? In this article, you will learn amazing facts about breast milk production in the first days, weeks and months.

Share this information

Your body is capable of producing breast milk for your baby at every stage of development. Understanding how milk production “turns on”, what happens to milk when you feed your baby, and why production adjusts to his needs as he grows, will help you start this amazing process in the right way. nine0003

Day one: milk production at birth

The baby is usually ready to breastfeed from birth. When he grabs the breast and begins to suck rhythmically, the milk-producing cells “turn on” and the formation of the first breast milk, colostrum, starts. ¹ Try to feed your baby as much as possible in the first hour of his life, and then as soon as he shows interest in feeding. This will help lay the foundation for good milk production later on. ²

The first days: the arrival of milk

At this stage, your body's level of progesterone, the
pregnancy hormone, which begins to fall after the placenta comes out, is reduced, and the hormones responsible for milk production - prolactin, insulin and hydrocortisone - are included in the work. These hormones will help start milk production. ³ Around the third day of your baby's life, milk will begin to come in and you will feel that your breasts have filled up and become noticeably firmer. ¹

First month: shaping milk production

During the first weeks, your body will be especially sensitive to the amount of milk produced as it learns to produce the right amount. Prolactin levels increase dramatically each time you empty your breasts, thereby helping shape the lactation process. It also contributes to the maturation of your milk in terms of composition. At this stage, transitional milk is produced and the amount continues to grow. ^3.4

For good long-term milk production, it is very important that you are close to your baby during the first few weeks. The more often you breastfeed, the more milk will be produced. This process resembles the law of supply and demand. Each time after emptying the breast, whether it is feeding the baby or pumping, even more milk will be produced.

Remember that it is normal for newborns to eat frequently, perhaps even every 45 minutes, and this does not mean that they are not getting enough milk. Frequent feedings help shape milk production, so feed your baby on demand, not on a schedule. nine0003

“In the first few weeks you may feel like you don’t have enough milk because your baby will be feeding all the time, but that’s okay,” says UK mom-of-two Jo, “We tend to think that the baby wants to eat every few hours, but that is not necessarily the case."

Don't forget that babies also breastfeed for comfort. Breastfeeding helps them calm down and adjust to their new life outside the womb. In addition, feeding helps to establish a connection between you. nine0003

Stable milk production in the first month

If you follow your baby's needs and feed him as often and for as long as he wants, milk production should adjust. ⁵

Some mothers try to increase the period between feedings so that the breasts can produce more milk during this time, but this should not be done, as this may have the opposite effect. ²

If you are unable to breastfeed directly for the first two weeks, express your milk to build and maintain your milk supply during this critical period and beyond. nine0003

Did you know that feeding your baby extra formula unnecessarily can reduce your milk production? The chest will not receive a signal to increase production, because it will not be emptied. In addition, if the baby sleeps longer after formula, he may miss his usual next feeding time.

This is a kind of “supplementing trap”. After three to four days of formula supplementation, during which the breasts have emptied less, the body will receive a signal that breastfeeding has stopped, and the amount of milk produced will begin to decrease. As a result, the baby will remain hungry and will need additional formula supplementation. And so on in a circle ... As a result, this will lead to really low milk production, and the baby will eat mainly the mixture. nine0003

Breast milk production after six weeks

After a month of breastfeeding, post-feeding bursts of prolactin secretion begin to decrease, milk matures, and the body gets used to producing as much milk as your baby needs. In fact, the chest begins to work "on autopilot." ⁴ You may also notice at this time that your breasts are softer and your milk flow has stopped.

At this stage, women often have fears of "losing milk". nine0021 However, this only means that milk production has been established and now fully meets the needs of the child. It is noteworthy that although the baby continues to grow, he will consume approximately the same amount of milk both at six weeks and at six months. You may notice that the baby began to suckle the breast longer, but less often. On some days he may eat a little less than usual - his appetite changes in the same way as an adult.

Now your body will produce exactly the amount of milk,
as much as your baby needs. Therefore, the more milk the baby
drinks (or you express), the more it will produce.

How does this happen? The reason for this is thought to be the so-called "feedback lactation inhibitor" that controls milk production. The more milk in the breast, ² the higher the inhibitor level, so a full breast produces less milk than one that has been emptied.

What is the rate of milk production? nine0011

Mothers often worry about their milk supply and think about how to increase it. However, if the baby is healthy and growing well, problems usually do not arise.

“I was worried that my newborn daughter was not getting enough milk as she was feeding very quickly and always from one breast even though I offered both,” says Marjorie, mother of two in the UK, “But when I pumped from using a breast pump, I was surprised at how much milk I produced, and calmed down. I just had to keep feeding her little and often.” nine0003

Keep in mind, however, that not all mothers are able to express a lot of milk right away. You can also try hand expressing milk and see if there is a change in breast fullness.

Transitional milk | Stages of breast milk production

During the first couple of weeks after birth, the composition of breast milk changes dramatically. Learn about the amazing properties of this transitional milk. nine0003

Share this information

A newborn changes literally every day, and the same can be said about breast milk. With the advent of milk, the breast can increase to an impressive size, and changes occur not only on the outside, but also inside. During the first week, the milk-producing cells and the connections between them are rebuilt and prepare the breast for the upcoming feeding. ¹ From now until about the end of the second week, they will produce what is called transitional milk. nine0013 2

“After the placenta is delivered, levels of progesterone, the pregnancy hormone, begin to decline rapidly,” explains Professor Peter Hartmann of the University of Western Australia, a leading authority on the composition of breast milk. “As progesterone levels decrease, milk synthesis increases and the composition is approaching the norm, although a couple more weeks are needed for the full maturation of the milk.

Breastmilk Stages: An Intermediate Phase

If colostrum is your baby's very first food and mature milk is his main food for a long time, then transitional milk is a kind of bridge between them. nine0003

They should be considered as three different stages of milk production, not three types of milk. The main components remain unchanged throughout breastfeeding, only their quantity changes depending on the circumstances. During the transition period, the composition of milk undergoes the most significant changes, and this happens every day in accordance with the changing needs of the child.

Milk changes because it contains bioactive components, including cells, hormones and beneficial bacteria. The transition to mature milk does not happen all at once: the composition changes gradually and in strict accordance with the developmental needs of the baby. nine0013 3.4

“The amount of milk produced by the mother has a major influence on the composition of milk,” says Professor Hartman. “The composition of milk at low and higher levels of production is different.”

Transitional milk: increase in quantity

As the baby grows, it needs more food and a different ratio of nutrients. The amount of milk produced during this period also increases significantly. You can produce 600-700 ml per day, ⁵ which is a very impressive amount compared to the small amount of colostrum that was produced in the early days. nine0003

"The composition of milk in all mammals varies according to the needs of the young"

Your breasts are now in “boosting” mode: your body is learning to produce the amount of milk your baby needs. The breast becomes more mature, as does the milk. Compared to colostrum, transitional milk contains more fat and lactose, a natural sugar that gives your baby energy. ²

“The level of lactose rises sharply in the first two or three days after birth,” says Prof. Hartmann, “The composition of fats also changes: the content of medium-chain fatty acids C10 and C12 increases. They are an easily digestible source of energy and have antiviral properties. In addition, sodium and chloride levels are greatly reduced during this period, so that the milk has a very low salt content.” nine0003

Protein: the right ratio

The protein content of breast milk does not stay the same either. There are two types of proteins in human milk: casein and whey. Under the influence of acid in the child's stomach, casein turns into a solid mass (cottage cheese) and gives a feeling of satiety for a longer time. It also has antimicrobial properties. Whey, on the other hand, is rich in antibodies and remains liquid, so it is easily absorbed, which is especially important for newborns. As the child's gastrointestinal tract strengthens, the ratio of casein to whey in milk gradually changes. If in colostrum it is about 90:10, then after a month it reaches 60:40, and after a year of breastfeeding, the balance is set at 50:50. ⁶

This ratio of proteins is ideal for humans, as our body grows relatively slowly and the brain is constantly growing and becoming more complex. In addition, it promotes the supply of all the essential amino acids that a child needs for the healthy development of the brain, eyes and other organs.

The amount of whey protein in human milk is significantly higher than that of other mammals. In cow's milk, the ratio of whey and casein is the opposite: 20:80 (therefore, it is not suitable for feeding children under one year old). nine0013 7

“Milk is designed to perform a specific task,” continues Professor Hartmann, “Some components are present in all milk, such as proteins and fats, but if you look at which proteins and which fats, it becomes clear which animal belongs to milk. The composition of milk in all mammals varies depending on the needs of the young.

Changing the protective properties of transitional milk

Although your baby is still very young, already in the first couple of weeks he begins to develop his own immune system, and now he needs your direct protection a little less. nine0003

The concentration of protective enzymes and antibodies in breast milk changes accordingly. The content of some substances, in particular lactoferrin (protective enzyme) and secretory immunoglobulin A (antibody), decreases, while other substances, such as the antibacterial enzyme lysozyme, on the contrary, increase. ⁸

“The protein content of milk decreases around the same time,” says Prof. Hartmann, “The synthesis of protective proteins occurs at the same rate, but they are more diluted due to increased milk production.” nine0003

The concentration of minerals such as zinc, copper and magnesium, which support the development of the child's immune system, also decreases as the immune system strengthens. ⁹

When breast milk becomes fully mature

During the transition period, the composition of breast milk changes significantly. By the end of the first month, it becomes fully mature. This means that the child will be able to eat them further as they grow. The composition of milk will no longer change much, no matter how long you continue breastfeeding - a few months, a year or more. nine0003
