Newborns typically need 1.5 to 3 ounces of milk per feeding, with increasing amounts as they grow, but individual needs can vary.
How Much Milk Should I Feed My Newborn? | Newborn Feeding Guidelines
Feeding a newborn can be both an exciting and nerve-wracking experience for new parents. I remember when my sister had her first baby, she often wondered if her newborn was getting enough milk. How much is too much? How little is too little? This concern is common, especially for first-time parents, as newborns don’t exactly come with feeding instructions.
In this article, we’ll explore how much milk your newborn should be drinking based on their age and weight, how to spot signs that they’re getting enough, and when to adjust feeding amounts. Whether you’re breastfeeding, bottle-feeding, or using formula, understanding your baby’s feeding needs is key to ensuring healthy growth and development.
Milk Intake for Newborns | How Feeding Changes in the First Weeks
During the first few weeks of life, a newborn’s feeding needs change rapidly. It’s important to feed them on demand, which means offering milk whenever they show signs of hunger. In the early days, babies typically feed 8-12 times in 24 hours, and their intake increases gradually as they grow.
Days 1-3: Colostrum and Small Stomachs
In the first few days after birth, your baby’s stomach is very small—about the size of a cherry. During this time, they only need small amounts of milk, usually 1-1.5 ounces per feeding. If you’re breastfeeding, your baby will receive colostrum, a nutrient-dense fluid that’s produced in small quantities but is incredibly rich in antibodies and nutrients.
Days 4-7: Increasing Appetite
By the end of the first week, your baby’s stomach will grow to about the size of a walnut, and they’ll need more milk. By this time, most newborns drink 1.5-3 ounces per feeding every 2-3 hours. You’ll likely notice your baby becoming more alert and feeding more actively during this stage.
Weeks 2-3: Steady Growth
At 2-3 weeks old, babies typically consume 2-3 ounces per feeding. This amount will gradually increase as they continue to grow. You may also notice more frequent feedings during growth spurts, which are common around this time.
Table 1: Newborn Milk Intake by Age (First Month)
| Age of Newborn | Milk Per Feeding (Approx.) | Frequency of Feedings |
| 1-3 days | 1-1.5 ounces | 8-12 times per day |
| 4-7 days | 1.5-2 ounces | Every 2-3 hours |
| 2-3 weeks | 2-3 ounces | Every 2-3 hours |
How to Know if Your Baby is Getting Enough Milk | Signs of Adequate Feeding
One of the biggest concerns for new parents is whether their baby is getting enough milk. Babies can’t tell you when they’re full, but they do give signals. Here are some clear signs that your baby is getting enough milk:
1. Wet and Dirty Diapers
A well-fed baby will produce at least 6 wet diapers and 3-4 dirty diapers each day by the time they’re a week old. In the early days, bowel movements may occur more frequently, but as your baby’s digestive system matures, the frequency may decrease slightly.
2. Steady Weight Gain
Most newborns lose weight in the first few days after birth, but by the end of the first week, they should start gaining weight steadily. On average, babies gain 5-7 ounces per week during the first month. Regular weight check-ups with your pediatrician will confirm whether your baby is gaining weight appropriately.
3. Baby Appears Satisfied After Feedings
A satisfied baby will usually relax their body, release the breast or bottle on their own, and seem calm or sleepy after feeding. If your baby seems content after most feedings, it’s a good sign they’re getting enough milk.
Table 2: Signs That Your Baby is Getting Enough Milk
| Sign | What It Means | How to Monitor |
| Wet and dirty diapers | Adequate hydration and digestion | At least 6 wet and 3 dirty diapers per day |
| Steady weight gain | Proper nutrition and growth | 5-7 ounces gained per week |
| Baby appears satisfied | Baby is full and content after feedings | Look for relaxed posture and drowsiness |
Breastfeeding vs. Formula Feeding | Differences in Milk Intake
Breastfeeding and formula feeding both provide essential nutrition for your newborn, but the amount of milk needed can differ slightly between the two.
Breastfeeding
When breastfeeding, it can be harder to track exactly how much milk your baby is consuming, but that’s okay—your body adjusts to produce the amount your baby needs. In the early weeks, it’s normal for babies to cluster feed (feeding frequently in short bursts), especially during growth spurts. As long as your baby is having regular wet diapers and gaining weight, they’re likely getting enough milk.
Formula Feeding
With formula feeding, it’s easier to measure how much milk your baby is drinking. On average, formula-fed babies consume about 2-3 ounces per feeding in the first few weeks, gradually increasing to 3-4 ounces by the end of the first month. Formula takes a bit longer to digest than breastmilk, so formula-fed babies may go slightly longer between feedings.
Supplementing With Formula
Some mothers choose to supplement breastfeeding with formula, especially if milk supply is low or if the baby is not gaining weight as expected. If you’re supplementing, it’s important to follow your pediatrician’s recommendations on how much formula to give, as overfeeding can lead to discomfort or unnecessary weight gain.
When to Increase Your Newborn’s Milk Intake | Signs to Watch For
As your baby grows, their milk intake will need to increase. Here are some signs that it might be time to offer more milk at each feeding:
1. Baby is Still Hungry After Feedings
If your baby is sucking on their hands, turning toward the breast or bottle shortly after feeding, or showing signs of hunger like rooting or crying, they may not be getting enough milk. Try offering a little more milk at the next feeding to see if they seem more satisfied.
2. Growth Spurts
Newborns often experience growth spurts around 2-3 weeks, 6 weeks, and 3 months. During these times, they may seem hungrier than usual and want to feed more often. This is perfectly normal and usually lasts a few days to a week.
3. Longer Stretches of Sleep
As your baby starts to sleep longer stretches at night, they may need to take in more milk during daytime feedings. If they’re going 4-5 hours between feedings at night, you might need to offer more ounces during the day to ensure they’re still getting enough milk overall.
Table 3: Signs That Your Baby Needs More Milk
| Sign | What It Indicates | What to Do |
| Baby seems hungry after feeding | Milk intake may not be sufficient | Offer additional ounces at the next feeding |
| Growth spurt | Increased appetite due to rapid growth | Feed more frequently or increase milk amount |
| Longer nighttime sleep | Baby may need more milk during the day | Offer more ounces during daytime feedings |
Common Newborn Feeding Challenges | Overfeeding and Underfeeding
Feeding a newborn can sometimes feel like a balancing act, and it’s easy to worry about overfeeding or underfeeding. Let’s look at how to recognize and address these challenges.
Overfeeding
Overfeeding is more common in bottle-fed babies, as it’s easier to push extra milk when a baby finishes a bottle quickly. Signs of overfeeding include:
- Frequent spit-up: If your baby is spitting up often after feedings, it could be a sign they’re getting too much milk at once.
- Gassiness or fussiness: Overfeeding can cause digestive discomfort, leading to fussiness or gassiness after meals.
- Unnecessary weight gain: Rapid weight gain that exceeds normal growth rates may indicate overfeeding.
To prevent overfeeding, watch for signs that your baby is full, such as turning away from the bottle, and don’t force them to finish the milk if they seem satisfied.
Underfeeding
Underfeeding can lead to slower weight gain, dehydration, or a baby who’s fussy because they’re not getting enough milk. Signs of underfeeding include:
- Infrequent wet diapers: Less than 6 wet diapers per day could indicate dehydration.
- Lethargy or sleepiness: A baby who isn’t getting enough milk may be too tired or weak to cry or feed effectively.
- Slow weight gain: If your baby isn’t gaining weight as expected, it’s important to consult your pediatrician to ensure they’re getting enough milk.
