Breastfeeding: How much milk is enough for a newborn?

Do you remember how fast those months of pregnancy went and how much your baby (or babies!) grew in that amount of time? It began as a bundle of cells and evolved into a package of joy. This trend continues outside the womb, with significant changes occurring over a relatively short period. The first two weeks of a newborn's life are considered the most challenging, as the mother and child are on a learning curve, trying to keep up with hunger cues and satiety signals.

For a quick reference, here is a general guide to feeding amounts for babies. Remember that every baby is different, and these are just averages.

Your baby grows incredibly fast, and their feeding needs evolve just as quickly. Here’s a breakdown of what to expect in the first month of the baby's life.

During the first few days, your body produces colostrum, often referred to as "liquid gold." This early milk is thick, yellowish, and packed with antibodies and nutrients. A newborn's stomach is tiny—about the size of a cherry—and cannot stretch to hold more than 5-10 ml per feeding.

Because of this small capacity, feedings will be slow but very frequent, with an aim of 10-12 feedings in a 24-hour period. It might feel like you're constantly nursing, and that’s perfectly normal. This frequency is essential for providing your baby with the calories they need and helps prevent issues like jaundice and low blood sugar.

Around days 3 to 5, your mature milk will come in. You'll notice it's thinner and whiter than colostrum. As your milk supply increases, your baby will start taking in more volume, typically between 10 ml to 2 ounces per feeding.
This is also when you can use diaper output to gauge how well your baby is eating. Stools should transition from black and tarry (meconium) to green, and finally to a mustard-yellow color by day 4 or 5. A key indicator of adequate intake is counting wet diapers: by day four, you should be seeing four or more wet diapers a day, increasing to six or more after that.
Amounts per feeding: 10 ml to 2 oz 
Amounts per day: 4 oz to 12 oz 

It's normal for newborns to lose up to 10% of their body weight in the first few days. During this period, the goal is to regain their birth weight, which typically occurs around the second week. As your baby’s stomach grows, feedings may become longer (around 20 minutes) and more established, with amounts increasing to 2-4 ounces.

You may also experience "cluster feeding," especially in the evenings. This is when your baby wants to nurse very frequently, sometimes every 30 minutes, with short naps in between. This is a completely normal phase. It doesn't mean you have a low milk supply; it's your baby's way of fueling up for a longer sleep stretch and stimulating your body to produce more milk for their future needs.

Amounts per feeding: 2 to 4 oz, less for clustering 
Amounts per day: 12 to 24 oz

By the end of the first month, you and your baby are likely finding a breastfeeding rhythm. Your baby can now take in 2-4 ounces of milk per feeding. From one to six months of age, a breastfed baby's milk intake remains surprisingly constant, averaging about 25-35 ounces per 24-hour period.
At this stage, it’s best to continue feeding on demand, responding to your baby’s unique hunger cues. Waiting to introduce a pacifier until breastfeeding is well-established (usually around 3-4 weeks) is often recommended to ensure your baby is nursing effectively and conserving energy for growth and development.

Amounts per day: 12-24 oz

Beyond tracking ounces and diapers, your baby gives you clear signals. Learning to read these signs is one of the most reassuring skills you can develop.

Consistent monitoring provides the best evidence that your baby is thriving:

• Diapers: Look for at least 6+ wet diapers and 3+ soft, yellow stools per day after the first week.

• Weight: Your baby should regain their birth weight by 10-14 days old and then continue to gain weight steadily.

• Behavior: A well-fed baby will seem content and satisfied after most feedings and will be alert and active when awake.

Trust your instincts. If you feel something is off or you're struggling with breastfeeding, don't hesitate to seek professional help. An International Board Certified Lactation Consultant (IBCLC) is a valuable resource.

Contact an IBCLC or your pediatrician if you notice:

• Your baby is not regaining their birth weight by two weeks.

• Fewer than six wet diapers in a 24-hour period (after day 5).

• Your baby is consistently fussy, lethargic, or seems hungry all the time.

• You are experiencing significant pain during latching or throughout feedings.

Remember, you and your baby are a team on a learning curve. Being patient with yourself and seeking support are key parts of a successful breastfeeding journey.
