How Much Should a Newborn Eat? Find Out Now!

So, you’re sitting there with your little newborn, and now you're wondering, “How much should a newborn eat? That’s a super common question, and honestly, it makes total sense to ask.

Let’s be real—babies don’t come with instruction manuals. One minute they’re sleeping, the next they’re crying, and you’re left trying to figure out if they’re hungry, tired, or just need a cuddle. 

It can definitely be overwhelming, especially when everyone around you has a different opinion. That’s why, in this blog, we’ll talk about how much your newborn should eat, how often, and what signs to look for. 

Let’s figure it out together. 

Why Is Understanding Newborn Feeding So Important?

When babies are newborns, everything they eat fuels their growth and helps their little bodies and brains develop properly. Whether you’re breastfeeding, giving formula, or doing both, knowing how much your baby needs to eat helps you feel confident that your baby is getting what they need.

Feeding your newborn isn’t about sticking to strict rules; it’s about understanding your baby’s hunger signs and helping them grow strong and healthy.

How Often Should a Newborn Eat?

Newborns usually feed on demand. That means whenever they seem hungry, not necessarily at exact times on a schedule. Most newborns usually eat every 2 to 3 hours in the first few weeks.

Here’s a quick tip: if your baby sleeps longer than 4 to 5 hours in these early weeks, gently wake them up to feed. It might sound tough, but newborns need to eat regularly to gain weight well.

If you’ve ever asked, “How often do infants eat?” remember that every baby is a little different, but feeding every 2 to 3 hours is very common.

How Can You Tell When Your Newborn Is Hungry?

 

Babies can’t tell us with words, but they show hunger in ways we can learn to recognize. Some early hunger signs are:

• Moving their head side to side

• Opening their mouth or sticking out their tongue

• Putting their hands or fists to their mouth

• Turning their head toward your cheek if you touch it (this is called the rooting reflex)

• Puckering their lips like they want to suck.

One thing to know: crying usually comes last. So, try to feed your baby before they start crying, because crying means they’re really hungry or upset. Also, remember babies cry for lots of reasons — maybe they’re tired, uncomfortable, or just want a cuddle.

How Much Should a Newborn Eat?

In the very beginning (first few days), newborns usually take about 1 to 2 ounces (that’s 30 to 60 milliliters) at each feeding. By the time they are around 2 weeks old, most babies drink 2 to 3 ounces per feeding. At 1 month old, many babies will take 3 to 4 ounces at a time.

But here’s the thing: instead of counting ounces too strictly, it’s best to watch your baby’s hunger and fullness cues. If they slow down sucking, turn their head away, or stop feeding, they’re likely full.

Feeding Chart for Newborns: How Much and How Often

To make things simple, here’s a feeding chart showing typical amounts your newborn might eat and how often they feed:

This chart helps answer common questions like how many ounces a newborn should eat or how much milk a newborn should drink. Keep in mind, this is a general guide—your baby might eat a bit more or less, and that’s okay.

Breast Milk vs. Formula Feeding for Newborns

If you’re breastfeeding, babies usually start with about 1 to 2 ounces of breast milk per feeding. By 2 weeks, this often goes up to 2 to 3 ounces.

For formula-fed babies, the pattern is similar: around 1 to 2 ounces per feeding in the first week, increasing to about 3 to 4 ounces by the time they’re 1 month old.

Formula-fed babies sometimes feed a little less often, maybe every 3 to 4 hours, because formula can be a bit heavier on the tummy. No matter how you feed, it’s important to check that your baby is producing enough wet diapers—aim for at least 2 to 3 wet diapers daily in the first few days, then 5 to 6 wet diapers after that. 

This is a good sign that your baby is getting enough milk.

How Can You Tell If Your Newborn Is Eating Enough?

You’ll know your baby is eating well if:

• They seem happy and content after feeding

• They have plenty of wet and dirty diapers regularly

• They’re steadily gaining weight (your pediatrician will check this)

If you ever wonder how many ounces my 2-week-old should be eating? Or how much formula a newborn should eat? Remember, these numbers are just averages. Every baby’s needs are unique. Always talk to your doctor if you have concerns.

Common Newborn Feeding Concerns

Sometimes babies go through growth spurts, usually around 1 to 2 weeks old, when they suddenly seem hungrier and want to eat more often. To avoid overfeeding, watch for fullness signs and don’t force your baby to finish the bottle or breast if they stop feeding. Also, fussiness or crying doesn’t always mean hunger. It could be tiredness, discomfort, or even just needing a cuddle.
