When Does Breast Milk Come In? Understanding Lactogenesis
Breast milk typically “comes in” or becomes abundant between 3 to 5 days postpartum, marking the shift from colostrum to mature milk. This process, called lactogenesis II, involves hormonal changes triggered by the delivery of the placenta and requires frequent stimulation of the nipples.
The Journey to Mature Milk: A Comprehensive Guide
For expecting and new parents, understanding the timeline of breast milk production is crucial for a successful breastfeeding journey. Knowing what to expect, recognizing the signs of adequate milk production, and being prepared to troubleshoot potential challenges can significantly reduce anxiety and boost confidence. This article delves into the intricacies of lactogenesis, providing you with the information you need to navigate this natural but sometimes challenging process.
What is Lactogenesis?
Lactogenesis refers to the process of milk production within the mammary glands. It’s generally divided into two stages:
Lactogenesis I: This stage begins during pregnancy, typically in the third trimester. Hormones like progesterone and estrogen prepare the breasts for milk production, but progesterone inhibits the full onset of milk secretion. During this phase, the breasts produce colostrum.
Lactogenesis II: This stage begins after delivery, typically between 3 and 5 days postpartum. The expulsion of the placenta results in a dramatic drop in progesterone levels. This hormonal shift allows prolactin, the primary hormone responsible for milk production, to surge. With frequent nipple stimulation through breastfeeding or pumping, mature milk “comes in” – the breasts become fuller, and milk production increases substantially.
The Importance of Colostrum
Before mature milk arrives, your baby receives colostrum, a thick, yellowish fluid often referred to as “liquid gold.” Colostrum is packed with:
- Antibodies: Providing vital immune protection to the newborn.
- Protein: Essential for growth and development.
- Low fat content: Easily digestible for the newborn’s immature digestive system.
- Growth factors: Promoting gut health and development.
Although the amount of colostrum is small, it’s precisely what your baby needs in the first few days of life. Its high concentration of nutrients and immune factors sets the stage for a healthy start.
Factors Affecting When Milk Comes In
Several factors can influence the timing of lactogenesis II:
- First-time mothers: Milk may take slightly longer to come in for first-time mothers compared to those who have breastfed previously.
- Cesarean delivery: Cesarean sections can sometimes delay milk production due to hormonal imbalances or delayed skin-to-skin contact.
- Medical conditions: Certain medical conditions, such as polycystic ovary syndrome (PCOS) or thyroid disorders, can affect milk supply.
- Medications: Some medications, like certain antihistamines or decongestants, can interfere with prolactin levels and delay milk production.
- Stress: High levels of stress can also negatively impact hormone balance and delay lactogenesis.
- Retained Placental Fragments: Sometimes small pieces of the placenta are retained within the uterus. This can delay milk coming in as the placenta is still releasing progesterone which actively inhibits prolactin.
Signs of Milk Coming In
Recognizing the signs of lactogenesis II can help you feel confident that your milk supply is establishing:
- Breast fullness and engorgement: The breasts will feel noticeably fuller, heavier, and potentially even tender or slightly painful.
- Increased milk production: Milk will flow more readily when the baby nurses or when you pump.
- Changes in milk appearance: The milk will transition from the thick, yellowish colostrum to a thinner, whiter or bluish-tinged mature milk.
- Increased wet and soiled diapers: As your baby consumes more milk, their output will increase accordingly.
Common Mistakes That Can Delay Milk Coming In
Avoid these common pitfalls to optimize your milk supply:
- Infrequent breastfeeding: Nipple stimulation is crucial for stimulating prolactin release. Aim for at least 8-12 breastfeeding sessions per day in the early days.
- Supplementing with formula unnecessarily: Offering formula can reduce the baby’s demand for breast milk, decreasing nipple stimulation and potentially hindering milk production.
- Incorrect latch: A poor latch can prevent effective milk removal, leading to decreased stimulation and reduced milk supply.
- Not seeking help: If you’re experiencing difficulties with breastfeeding, don’t hesitate to consult with a lactation consultant or healthcare provider. Early intervention can address potential problems and help you achieve your breastfeeding goals.
Strategies to Promote Lactogenesis
Here are some tips to encourage a healthy milk supply:
- Early and frequent breastfeeding: Start breastfeeding as soon as possible after delivery and continue to nurse frequently (8-12 times per day).
- Skin-to-skin contact: Place your baby skin-to-skin on your chest immediately after birth and continue this practice regularly. Skin-to-skin contact promotes bonding, regulates the baby’s temperature, and stimulates milk production.
- Proper latch: Ensure that your baby has a deep, comfortable latch. A lactation consultant can help you assess and improve your latch technique.
- Adequate hydration and nutrition: Drink plenty of water and eat a healthy, balanced diet.
- Rest: Prioritize rest as much as possible. Fatigue can negatively impact milk production.
- Pumping: If your baby is unable to nurse effectively, or if you need to supplement, use a breast pump to stimulate milk production.
- Address any medical concerns: Work with your healthcare provider to address any underlying medical conditions that may be affecting your milk supply.

Frequently Asked Questions (FAQs)
What is “delayed lactogenesis,” and what causes it?
Delayed lactogenesis refers to a situation where mature milk does not come in by day 5 postpartum. It can be caused by various factors, including Cesarean delivery, retained placental fragments, medical conditions like PCOS or thyroid disorders, certain medications, stress, or infrequent breastfeeding. If you suspect delayed lactogenesis, seeking professional help from a lactation consultant is crucial to identify the underlying cause and implement appropriate interventions.
How much colostrum is normal for a newborn to consume?
Newborns typically consume relatively small amounts of colostrum in the first few days of life. A typical amount ranges from 5-7 ml per feed on day 1 to about 30 ml per feed by day 3. Remember, colostrum is nutrient-dense, so even small amounts provide significant benefits.
Can I increase my milk supply after it has already established?
Yes, you can often increase your milk supply even after it has established. Frequent breastfeeding or pumping, ensuring a proper latch, addressing any underlying medical conditions, and getting adequate rest and nutrition are all effective strategies. Galactagogues (medications or herbs that promote milk production) may also be considered under the guidance of a healthcare provider.
Is it normal for my breasts to feel engorged when my milk comes in?
Yes, engorgement is a common and normal symptom when mature milk comes in. It can cause the breasts to feel full, hard, and even painful. Frequent breastfeeding or pumping can help relieve engorgement and prevent complications like mastitis.
What is the difference between “foremilk” and “hindmilk”?
Foremilk is the milk released at the beginning of a feeding session, which tends to be higher in water content and lactose. Hindmilk is released later in the feeding and contains a higher fat content, which helps the baby feel full and gain weight. It’s important to allow your baby to fully drain one breast before switching to the other to ensure they receive both foremilk and hindmilk.
Does stress affect breast milk production?
Yes, stress can negatively affect breast milk production by interfering with hormone balance. Practicing relaxation techniques like deep breathing, meditation, or yoga can help manage stress and support milk supply.
Are there any foods or drinks that can help increase milk supply?
Certain foods and drinks, often referred to as galactagogues, are believed to help increase milk supply. Some common examples include oatmeal, fenugreek, and fennel. However, their effectiveness can vary, and it’s essential to consult with a healthcare provider before making significant dietary changes.
How do I know if my baby is getting enough milk?
Signs that your baby is getting enough milk include: adequate weight gain, frequent wet and soiled diapers, and contentment after feedings. Consulting with your pediatrician is recommended to monitor your baby’s growth and development.
Is it possible to breastfeed after a breast reduction or augmentation surgery?
Breastfeeding after breast reduction or augmentation surgery is possible but may be more challenging. The success of breastfeeding depends on the extent of the surgery and whether milk ducts and nerves were damaged. Consulting with a lactation consultant before and after delivery is highly recommended.
Can I breastfeed if I have inverted nipples?
Yes, it’s possible to breastfeed with inverted nipples. Techniques like nipple stimulation or using a breast pump can help draw out the nipples. A lactation consultant can provide guidance and support.
Can I breastfeed while taking medication?
Many medications are safe to use while breastfeeding, but some can pass into breast milk and potentially affect the baby. Always consult with your healthcare provider before taking any medication while breastfeeding to ensure it is safe for your baby.
How long should I breastfeed each time?
The length of each breastfeeding session can vary depending on the baby’s age and individual needs. As a general guideline, allow your baby to nurse on each breast for 10-20 minutes. It’s important to watch for signs that your baby is finished, such as releasing the nipple or falling asleep.
