Breastfeeding is one of the most important aspects of newborn care. It not only provides the baby with essential nutrients but also strengthens the bond between mother and child. One of the most common questions new parents have is: “How much breast milk can a newborn drink?” Understanding how much milk your baby needs is key to ensuring healthy growth and development.
In this article, we’ll provide a detailed guide on how much breast milk a newborn can drink, how feeding patterns evolve in the early days, and tips to help you navigate the breastfeeding journey with confidence.
Understanding Newborn Feeding Needs
A newborn’s stomach is incredibly small at birth, and they require frequent feedings to meet their nutritional needs. Unlike formula feeding, breastfeeding doesn’t always allow parents to measure the exact amount of milk a baby consumes. However, there are general guidelines based on a newborn’s age and developmental stage.
The First Few Days: Colostrum and Early Feeding
In the first 2-3 days of life, newborns consume colostrum, the initial milk produced by the mother. Colostrum is thick, yellowish, and packed with essential nutrients and antibodies that protect the baby from infections.
How much do newborns drink in the first days: A newborn’s stomach is only about the size of a marble (5-7 mL) during the first day, which is why they only need small amounts of colostrum—around 1 to 2 teaspoons (5-10 mL) per feeding.
Feeding frequency: Newborns typically nurse every 1-2 hours, or 8-12 times a day, during the first few days. The frequent feeding helps stimulate milk production for the transition to mature milk.
Day 3 to Day 5: Transitional Milk
Around day 3 to 5, your breast milk starts transitioning from colostrum to mature milk. This is when you may notice your breasts feeling fuller, a sign that your milk supply is increasing.
How much can a newborn drink during this period: By the third or fourth day, a newborn’s stomach has grown to the size of a walnut, holding about 22-27 mL (¾ to 1 ounce) per feeding.
Feeding frequency: The frequency remains similar, with your baby continuing to feed around 8-12 times a day. The frequent nursing is essential for establishing a good milk supply.
The First Week to One Month: Increasing Milk Intake
By the end of the first week, your baby’s stomach will have grown to hold about 45-60 mL (1.5 to 2 ounces) of milk per feeding. At this stage, your mature breast milk comes in fully, and your baby’s intake increases significantly.
How much can a newborn drink at 1 week: Most newborns will drink around 45-60 mL (1.5-2 ounces) of breast milk per feeding. By the time they are 2 weeks old, this amount typically increases to 60-90 mL (2-3 ounces) per feeding.
Feeding frequency: While the amount of milk per feeding increases, your baby will still nurse frequently—every 2 to 3 hours or 8 to 12 times per day. This frequent nursing ensures that your milk supply keeps pace with your baby’s growing appetite.
One Month and Beyond: Steady Growth
As your baby grows, so does their appetite. By the time your baby reaches one month of age, they may consume around 80-120 mL (3-4 ounces) per feeding. This amount continues to increase as your baby’s stomach grows and their caloric needs rise.
How much can a 1-month-old baby drink: Most babies at this age will take about 90-120 mL (3-4 ounces) of breast milk per feeding. By 2 months, they may consume as much as 120-150 mL (4-5 ounces) at each feeding.
Feeding frequency: Though the amount of milk per feeding increases, your baby may begin to stretch out their feeding intervals slightly, nursing every 2.5 to 3.5 hours. However, every baby is different, and some may continue to feed more frequently, especially during growth spurts.
Growth Spurts and Cluster Feeding
During the first few months, babies go through several growth spurts, which can temporarily change their feeding patterns. Growth spurts commonly occur around:
- 2-3 weeks
- 6 weeks
- 3 months
- 6 months
During a growth spurt, your baby may seem hungrier and demand to nurse more frequently. This is known as cluster feeding, where your baby might want to feed every hour or more often for short periods.
Cluster feeding is entirely normal and helps signal your body to produce more milk to meet your baby’s increasing needs. These growth spurts usually last a few days and then your baby’s feeding schedule returns to its usual pattern.
Signs Your Baby Is Getting Enough Milk
Since breastfeeding doesn’t allow you to measure exactly how much your baby is drinking, it’s important to watch for signs that they’re getting enough milk. Here are some key indicators:
1. Wet Diapers
A well-fed baby will produce at least 6 wet diapers per day after the first week. The number of wet diapers is a good indicator that your baby is getting enough fluids.
2. Bowel Movements
In the early days, your baby should have at least 3 to 4 bowel movements each day. The stool may change from thick, black meconium to mustard-yellow, seedy stools as the milk transitions from colostrum to mature milk.
3. Weight Gain
A baby who is feeding well will steadily gain weight. While most newborns lose some weight in the first few days after birth, they should regain this weight by about 10-14 days of age and continue gaining around 140-200 grams (5-7 ounces) per week during the first few months.
4. Contentment After Feedings
After a good feeding session, your baby should appear satisfied and content. They may fall asleep at the breast or seem relaxed with a soft, unhurried suckling pattern.
What If My Baby Seems Hungry After Feedings?
If your baby still seems hungry after feeding, there are a few things to consider:
Check your baby’s latch: A poor latch can prevent your baby from getting enough milk. Ensure your baby is latching deeply and effectively sucking.
Feed on demand: Make sure you’re feeding your baby whenever they show signs of hunger, even if it seems frequent. Early hunger cues include rooting, sucking on hands, or turning towards the breast.
Consult a lactation consultant: If you’re concerned about your milk supply or your baby’s feeding patterns, a lactation consultant can help assess your situation and provide guidance.
Factors That Affect How Much Breast Milk a Newborn Drinks
While there are general guidelines, every baby is unique, and several factors can influence how much breast milk a newborn drinks.
1. Birth Weight
Babies born at a lower birth weight or prematurely may need smaller, more frequent feedings to catch up on growth. Larger newborns may require more milk per feeding.
2. Feeding Efficiency
Some babies are efficient feeders and can consume a full meal in 10-15 minutes, while others may need more time to drink the same amount. Every baby has their own rhythm, so it’s important to be patient and attentive to their needs.
3. Milk Supply
Your milk supply is designed to adjust to your baby’s needs. The more frequently your baby nurses, the more milk your body produces. However, some mothers may experience challenges with milk supply, especially in the early days.
If you’re concerned about low milk supply, try feeding on demand, using both breasts during each feeding, and consider talking to a lactation consultant for additional support.
Feeding Cues: How to Know When Your Baby is Hungry
Newborns don’t follow a strict schedule, so learning to recognize your baby’s feeding cues is essential. Look for early hunger signs, such as:
- Rooting or turning their head toward the breast
- Sucking on their hands or fingers
- Smacking their lips
- Fidgeting or becoming more alert
Crying is often a late hunger cue, so try to feed your baby before they reach that stage.

Conclusion
Newborns have small stomachs and require frequent feedings to meet their nutritional needs. In the first few days, they consume small amounts of colostrum, gradually increasing their intake as your milk supply transitions to mature milk. By the end of the first week, newborns typically drink around 45-60 mL (1.5-2 ounces) of breast milk per feeding, increasing to 90-120 mL (3-4 ounces) by the first month.
Feeding on demand, recognizing your baby’s hunger cues, and being attentive to their needs will ensure that they are getting enough milk. Every baby is different, so trust your instincts and consult healthcare professionals or lactation experts if you have concerns about your baby’s feeding patterns or milk intake.
