How Much Should A 1-Week-Old Baby Eat? | Daily Amounts

Feeding a brand new baby is a big job, and many parents often catch themselves asking, in the dark at 3 a.m., how much should a 1-week-old baby eat? You want enough milk for steady growth, but not so much that your newborn feels uncomfortable.

How Much Should A 1-Week-Old Baby Eat Over 24 Hours?

Most healthy 1-week-old babies drink a total of about 16–24 ounces of breast milk or formula across 24 hours. That usually looks like 8–12 feeds a day, spaced roughly every 2–3 hours, including nights.

Formula-fed babies often take closer to 1–2 ounces per feed in the first week, then slowly move toward 2–3 ounces as their stomach grows. Breastfed babies usually take smaller amounts at each feed but come to the breast more often, so their overall daily intake lands in the same broad range.

Many clinicians also use a weight-based rule of thumb. By the end of the first week, plenty of babies take around 150–200 ml of formula per kilogram of body weight per day, which matches guidance from services such as the NHS formula milk guide.

Typical Formula Intake By Weight At One Week

If your baby takes bottles, a weight-based range can help you sanity-check how much goes in across a day. The table below shows common daily targets for a 1-week-old baby, based on the 150–200 ml per kilogram rule, converted to ounces and rounded for home use. Always mix formula as directed on the tin, and do not pressure your baby to empty a bottle if they turn away or seem relaxed before it is finished.

Baby’s Weight	Daily Formula Range	Approx Ounces Per Feed*
5 lb (2.3 kg)	12–16 oz per day	1.5–2 oz if 8 feeds
6 lb (2.7 kg)	14–18 oz per day	1.75–2.25 oz if 8 feeds
7 lb (3.2 kg)	17–22 oz per day	2–2.75 oz if 8 feeds
8 lb (3.6 kg)	19–24 oz per day	2.25–3 oz if 8 feeds
9 lb (4.1 kg)	21–27 oz per day	2.5–3.25 oz if 8 feeds
10 lb (4.5 kg)	24–30 oz per day	3–3.75 oz if 8 feeds
11 lb (5.0 kg)	26–33 oz per day	3.25–4 oz if 8 feeds

*These are ranges, not strict targets. Some feeds will be smaller and some larger.

What About A Breastfed 1-Week-Old Baby?

When a baby nurses at the breast, you cannot see ounces on a bottle, so the question how much should a 1-week-old baby eat can feel even trickier. The good news is that newborns are built to cue for milk often. Most breastfed babies nurse at least 8–12 times per day in the early weeks, including several night feeds.

During this stage, your baby’s job is to feed often and build your milk supply. Your job is to respond to cues and make sure latch and positioning feel comfortable. As long as weight gain, diaper counts, and alertness look healthy, the exact number of minutes at each breast does not matter.

Feeding Schedule For A One Week Old Baby: How Much And How Often

It helps to know what a fairly typical pattern can look like at one week of age, even though each baby follows their own rhythm.

How Often A One Week Old Baby Usually Feeds

Most 1-week-old babies feed every 2–3 hours from the start of one feed to the start of the next. Twelve feeds in 24 hours is still normal at this age, especially for breastfed babies who enjoy shorter but frequent snacks.

Some bottle-fed babies drift toward every 3 hours between feeds, especially overnight. There is a wide range of normal, so the best guide is your baby’s cues, not the clock.

Day Feeds And Night Feeds

In the first week, many babies mix up days and nights. Long stretches of sleep in the daytime with short bursts at night are common. You may need to wake your baby for feeds during the day if they sleep longer than about 3 hours at a time.

At night, most babies still wake at least every 3 hours for food. One longer stretch of sleep, maybe 3–4 hours, can show up after a cluster of evening feeds. Even that longer stretch still usually includes at least one feed.

Cluster Feeding And Growth Spurts

Around the end of the first week, some babies go through a short stretch of extra frequent feeding, often in the evening. They may want to nurse or take small bottles every hour for several hours in a row.

This pattern can feel intense, but it often reflects a normal growth spurt and a push to increase milk supply. As long as diapers stay wet and dirty and your baby settles at other times of day, short bursts of cluster feeding are usually not a sign of low milk.

Reading Hunger And Fullness Cues At One Week Old

Numbers and charts are helpful, yet your baby’s behavior gives the clearest signal. Learning early hunger cues keeps feeds calmer and supports your milk supply.

Early Signs Your Baby Is Ready To Eat

Before crying starts, many babies show subtle signs that they are ready for the next feed. You may see rooting movements, lip smacking, turning their head from side to side, or hands moving toward the mouth.

When you notice these early cues, offer the breast or bottle. Feeding during this calm stage often leads to a better latch, less air swallowed, and a more relaxed feed for both of you.

Signs Your Baby Has Had Enough Milk

Fullness cues help you avoid overfeeding with bottles and give you confidence that your baby is satisfied at the breast. After a good feed, most babies relax their fists, release the nipple on their own, and appear calm or sleepy.

With bottles, paced feeding gives your baby time to notice fullness. Hold the bottle more horizontally, pause every few minutes, and watch for slowing sucks. If your baby turns away or pushes the nipple out, that feed is probably done even if a small amount of milk remains in the bottle.

Wet Diapers, Weight Gain, And Growth Checks

When you wonder how much should a 1-week-old baby eat, diaper counts and weight checks provide concrete, day-to-day feedback.

What Wet And Dirty Diapers Tell You

By the end of the first week, most babies have at least 6 wet diapers and 3–4 stools per day. Breastfed baby stools often look mustard yellow and loose, while formula-fed baby stools can be a bit firmer and more tan.

Fewer wet diapers, dark urine, or hard pebble-like stools can point toward low intake or concentrated formula. If you see these patterns, talk with your midwife, pediatric nurse, or doctor for advice that fits your situation.

Weight Checks And Growth Charts

Many babies lose up to 7–10% of their birth weight in the first few days, then start to gain again by the end of the first week. Most are back to birth weight by around two weeks. Your care team will plot each weight on a growth chart instead of judging a single number.

The American Academy of Pediatrics shares a clear overview of daily formula ranges in its amount and schedule of formula feedings, which lines up well with the ranges in this article.

Sample 24-Hour Feeding Pattern For A 1-Week-Old

Every baby writes their own script, yet seeing a sample day can help you picture how the numbers on a chart play out in real life. This example assumes a baby who takes about 20 ounces in 24 hours with a mix of day and night feeds.

Time Of Day	Number Of Feeds	Notes
6 a.m. – 9 a.m.	2 feeds	Wake-up feed, then another before a nap
9 a.m. – 12 p.m.	2 feeds	Short awake windows with feeds before sleep
12 p.m. – 3 p.m.	2 feeds	Often a longer nap after a fuller feed
3 p.m. – 6 p.m.	2 feeds	Some babies start evening cluster feeding here
6 p.m. – 9 p.m.	2–3 feeds	Frequent feeds before the longest sleep stretch
9 p.m. – 3 a.m.	1–2 feeds	One longer sleep stretch, plus at least one feed
3 a.m. – 6 a.m.	1–2 feeds	Early morning feeds before the next day starts

When To Call Your Baby’s Doctor About Feeding

Charts and averages are helpful, yet they never replace care from someone who knows your baby. If something feels off, you never need to wait for a scheduled visit to reach out.

Red Flags With Feeding Amounts

Get same-day advice from your baby’s doctor or urgent care service if you notice any of these signs at one week old:

• No wet diaper for six hours or longer.
• Fewer than four wet diapers in 24 hours after day five.
• Dark urine, red or brown streaks, or dry lips.
• Weak suck, trouble staying awake to feed, or poor tone.
• Persistent vomiting (not just small milk spit-up) after feeds.
• Fast breathing, pale or blue color, or a floppy posture.

When Feeding Seems Nonstop

Sometimes the worry is not low intake but endless feeding. If your baby wants to nurse or take bottles every hour for most of the day and still seems unhappy, it is reasonable to ask for help.

You can review latch, positioning, and pumping plans with a lactation specialist, and your doctor can rule out issues such as tongue-tie, reflux, or low supply. Small adjustments often make feeds more comfortable for both of you.

Bringing It All Together For Your 1-Week-Old

There is no single perfect answer to the question how much should a 1-week-old baby eat, yet you can lean on a few steady anchors: typical daily ranges of 16–24 ounces, 8–12 feeds in 24 hours, steady wet diapers, and a baby who wakes to feed and relaxes well afterward.

Use the numbers in this guide as flexible guardrails, not rigid rules. If your baby falls outside these ranges or you feel uneasy, reach out early to your midwife, health visitor, pediatric nurse, or doctor. You know your baby best, and your instincts matter just as much as any chart.
