Most newborns take about 150–180 mL per kg in 24 hours, split into 8–12 feeds, with hunger cues guiding each session.
Feeding a brand-new baby brings lots of questions, and one of the biggest is volume. The right daily amount isn’t a single fixed number, because babies vary in weight, feeding method, and pace. Still, there are safe, evidence-based ranges you can use today, plus simple ways to adjust for your baby’s signals and growth.
Quick Math: Daily Milk Needs By Weight
Health agencies give two easy rules of thumb you can use right away: around 2½ oz per pound per day (about 75 mL per pound), and a similar range of 150–200 mL per kg per day. These line up closely, so they work well for planning bottles and checking totals across a full day.
| Weight (kg) | Weight (lb) | Daily Volume (mL) |
|---|---|---|
| 2.5 | 5.5 | 375–450 |
| 2.8 | 6.2 | 420–504 |
| 3.0 | 6.6 | 450–540 |
| 3.2 | 7.1 | 480–576 |
| 3.5 | 7.7 | 525–630 |
| 3.8 | 8.4 | 570–684 |
| 4.0 | 8.8 | 600–720 |
| 4.5 | 9.9 | 675–810 |
Use the table as a day-total check. Then divide by the number of feeds. Newborns feed often—8 to 12 times in 24 hours—so single-feed volumes are small at first and grow across the first weeks.
How Many Ml Should A Newborn Drink In A Day? By Age And Feeding Pattern
The phrase how many ml should a newborn drink in a day comes up the most in the first month. Here’s how the range plays out from birth, with both breast milk and formula in mind.
Days 0–2: Tiny Stomach, Many Feeds
In the first two days, the stomach is small and the best plan is frequent, cue-led feeds. Formula-fed babies often start with 30–60 mL per feed in that first week; breastfed babies may transfer smaller volumes in those early hours but feed more often to match supply with demand. Expect 8–12 feeds in 24 hours, sometimes more on day two.
Days 3–7: Volume Rises
Milk volume climbs fast over the first week. Many babies settle around 30–60 mL per feed by the end of week one, still with 8–12 feeds in a day. Total daily intake begins to approach the weight-based ranges in the table above.
Weeks 2–4: Toward A Steadier Rhythm
By the end of the first month, many babies take 90–120 mL per feed. Bottles may spread out to every 3–4 hours for formula. Breastfed sessions can still cluster in the evening or swing shorter in the day—both patterns are normal while the daily total stays in range.
Close-Variant Keyword: How Many Milliliters Should Newborns Drink Per Day — Practical Rules
Two simple tools keep you on track:
- Weight rule: 150–180 mL per kg per day (or about 2½ oz per lb per day) as a planning guide.
- Hunger and satiety cues: Rooting, hand-to-mouth, and steady swallowing say “start”; turning away, sealed lips, or relaxed hands say “done.”
These two points work together. If your baby wants a bit more at one feed, totals often level out later in the day. If they take less at a feed, the next one may be sooner.
Breastfeeding: What To Expect In The First Month
Breastfed babies often feed more often in the early weeks. The milk they get per session grows as supply builds and latch improves. Many families see evening clusters—several shorter feeds in a row—then a longer stretch overnight. That still fits a healthy 24-hour total.
If you’re pumping, store in smaller portions at first, like 45–60 mL bottles, to limit waste. As your baby starts finishing those easily, move up in 15–30 mL steps.
Formula Feeding: Safe Ranges And Pace
Start smaller and increase as your baby asks for more. Newborns on formula commonly take 30–60 mL per feed during the first week, then 60–90 mL, reaching 90–120 mL by the end of the first month. Many do well with paced-bottle techniques, which mimic the flow changes of breastfeeding and help babies stop when full.
Worked Examples Using Real Weights
Example A: 3.2 kg Baby
Daily guide: 480–576 mL. With 10 feeds per day, that lands near 48–58 mL per feed on average. Early in week one, single feeds may be below that while totals catch up by day’s end.
Example B: 4.0 kg Baby
Daily guide: 600–720 mL. With 9 feeds per day, you’re near 65–80 mL per feed on average. Growth spurts can bump this up for a few days, then settle back.
Signals That Intake Is On Track
- Output: By day 4–5, several wet nappies and regular stools.
- Swallowing: You can hear or see steady swallows during the active part of the feed.
- Rhythm: Feed, wake, short sleep cycles that feel repeatable across the day.
- Weight: Regaining birth weight by about two weeks, then steady gains.
If weight checks lag or output is low, reach out to your baby’s doctor and a lactation specialist. Early tweaks make a big difference.
Bottle Prep, Hygiene, And Safe Storage
Wash hands before every prep, use clean bottles, and follow mixing directions exactly. If using powdered formula, use the scoop that comes with the tin and level it. Discard any milk left in the bottle after a feed. In the fridge, fresh breast milk can be stored for several days; formula should be mixed closer to feeding time unless your brand’s label says a made-ahead window is allowed.
When Daily Totals Sit Outside The Range
Some babies need more than the guide, and some need less. Preterm infants, babies under treatment, or those with poor weight gain often have tailored plans. If your baby is finishing every bottle fast and still cueing for more, increase each feed in small steps, like 15 mL at a time. If they leave milk often and weight checks look fine, you can trim back a little.
How Many Ml Should A Newborn Drink In A Day? Common Week-By-Week Ranges
Use this as a broad map during the first week, blending what you see with your baby’s cues. The daily number still comes from weight, but feed-by-feed amounts grow fast.
| Day Of Life | Per Feed (mL) | Feeds / 24h |
|---|---|---|
| Day 1 | 5–10 | 8–12+ |
| Day 2 | 15–30 | 8–12+ |
| Day 3 | 20–30 | 8–12 |
| Day 4 | 30–45 | 8–12 |
| Day 5–6 | 30–60 | 8–12 |
| Day 7 | 30–60 | 8–12 |
| End Of Week 1 | 45–60 | 8–12 |
These early numbers are small compared with your end-of-month bottles, and that’s normal. Frequent feeds help build supply and keep babies content while their tummies grow.
Breast Milk Vs. Formula: Does The Daily Total Change?
The daily total is driven more by weight and growth than by milk type. Formula-fed babies may take larger single bottles and go slightly longer between feeds once the first week passes. Breastfed babies often keep shorter gaps, especially in the evening. Over 24 hours, the totals are close when growth is steady.
Cluster Feeds, Growth Spurts, And Evening Patterns
Short, frequent evening sessions show up in many homes. That pattern can raise the nightly total by a small amount for a few days. Offer both sides if breastfeeding and watch for steady swallowing. With bottles, keep the nipple flow suited to age and use paced techniques so stopping feels easy.
How To Adjust Feeds Safely
- Go gradual: Change bottle size in 15–30 mL steps and review output and comfort.
- Follow the day total: Keep an eye on the 150–180 mL/kg guide and your weight checks.
- Use cues: Start when cueing, stop at early signs of fullness; don’t push to finish every bottle.
Red Flags Worth A Call
- Few wet nappies after day 3, dark urine, or dry mouth.
- Long, sleepy stretches with missed feeds in the early weeks.
- Poor latch pain that doesn’t ease after position fixes.
- Not regaining birth weight by about two weeks.
Putting It All Together
Your action plan is simple: use the weight-based daily guide, aim for 8–12 feeds early on, and let cues shape each session. Keep bottles modest at first and scale up in small steps. Watch nappies and weight as your scoreboard. If anything feels off, loop in your baby’s doctor and a lactation specialist early.

The phrase how many ml should a newborn drink in a day shows up in every parenting chat for a reason. With a clear range, steady cues, and regular checks, you’ll find a rhythm that fits your baby and keeps growth on track.
