How Much Milk Does a Newborn Need? Feeding Amounts by Age

Realistic feed amounts from day 1 to 12 months — and the signs to watch instead of the clock.

Every Australian parent asks this in the first week. The honest answer: babies aren't calculators. But there are realistic guide ranges, and there are far better signs of enough than ml on a bottle. Here's what Maternal Health Nurses and the Australian Breastfeeding Association recommend.

Newborn stomach size

Day 1: cherry — 5–7ml per feed.
Day 3: walnut — 22–27ml per feed.
Day 7: apricot — 45–60ml per feed.
1 month: egg — 80–150ml per feed.

Formula guide volumes (24-hour)

0–1 month: ~150ml per kg of body weight per day.
1–6 months: ~120ml per kg per day, max around 1000ml/day.
6–12 months: ~90ml per kg, dropping as solids increase.

Split across 6–8 feeds in the early weeks, fewer as baby grows.

Breastfeeding — feed cues, not ml

Breastfed babies self-regulate. Watch for early feeding cues (rooting, hands to mouth, soft sounds) rather than the clock. Most newborns feed 8–12 times in 24 hours. Cluster feeds in the evening are normal and not a sign of low supply.

Signs your baby is getting enough

6+ heavy wet nappies a day after day 5.
Yellow, soft poos (breastfed) or regular formed poos (formula).
Steady weight gain — most regain birth weight by 2 weeks.
Alert and settled between most feeds.
Audible swallows during breastfeeds.

When to seek support

Speak to your Maternal & Child Health Nurse, GP, or call the Australian Breastfeeding Association Helpline (1800 686 268) if baby has fewer than 6 wet nappies a day after week 1, isn't back to birth weight by 2 weeks, or is consistently unsettled around feeds.

Frequently asked questions

How do I know if my breastfed baby is getting enough?

Wet nappies, steady weight gain, and a settled baby between feeds — not ml on a bottle.

How often should a newborn formula-feed?

Every 2–4 hours, 6–8 feeds in 24 hours in the first month.

Can I overfeed a formula-fed baby?

Yes. Watch for paced bottle-feeding cues — turning head away, slowing down, milk dribbling out.

When can babies sleep through without a feed?

Most babies don't reliably do 8-hour stretches until 4–6 months.

Should I wake my newborn to feed?

In the first 2 weeks, wake every 3–4 hours to feed if baby is sleeping past that until weight gain is established.

A realistic 24-hour intake by age

Age	Feeds per 24 hours	Approx volume per feed (formula)	Total per 24 hours (formula)
Day 1	8–12	5–7ml	30–60ml
Days 2–3	8–12	15–30ml	200–300ml
Week 1	8–10	45–60ml	400–500ml
2–4 weeks	7–9	60–90ml	500–650ml
1–2 months	6–8	90–150ml	700–900ml
2–4 months	5–7	120–180ml	800–1000ml
4–6 months	4–6	150–210ml	800–1000ml
6–12 months	3–5 + solids	180–240ml	600–900ml

Paced bottle feeding — why it matters

The biggest cause of overfeeding (and reflux complaints) is fast bottle feeds. Paced feeding lets baby control intake, mimicking the rhythm of breastfeeding.

Hold baby semi-upright, not reclined.
Hold bottle horizontal so the teat is just filled with milk.
Tickle baby's lips with the teat and let them latch.
Pause every 30–60 seconds — tilt the bottle down for 5 seconds to give a breather.
Switch sides halfway through the bottle to mimic breastfeeding.
Stop the moment baby turns away, even if milk is left.

Cluster feeding decoded

Cluster feeds — short, frequent feeds bunched together, usually in the late afternoon or evening — are normal and helpful. They are not a sign of low milk supply. They:

Build milk supply for the next growth spurt.
Tank baby up before the longest sleep stretch.
Regulate baby's nervous system after an overstimulating day.

Common cluster windows: days 2–3, week 2, week 6, 3 months, 4 months. Each phase usually lasts 2–4 days.

When formula amounts look wrong

If your baby is consistently drinking far above or below guide volumes, talk to your MCH nurse. Often the answer is a feed-flow tweak, a longer pause to burp, or simply slowing things down. Avoid switching brands unless your GP advises it — most formula changes cause more upset than they solve.

Common worry: "Is my baby getting enough?"

This is the single most common question in the first six weeks. The reassuring truth: nature designed babies to ask for what they need. Watch the baby, not the bottle.

Signs of a well-fed baby

6+ heavy wet nappies a day after day 5.
Regular soft yellow poos (breastfed) or formed tan poos (formula).
Steady weekly weight gain — usually 150–200g/week in the first 3 months.
Alert during awake windows, settled during sleep.
Skin tone good, mouth and lips moist.

Subtle signs to act on

Fewer than 6 wet nappies in 24 hours after the first week.
Sleepy baby who needs waking for every feed.
Crying right after feeds, every time.
Not regaining birth weight by 2 weeks.
Strong-smelling, dark urine.

None of these on its own is a crisis — but bring it up with your Maternal & Child Health Nurse promptly.

Breastfeeding supply: myths to ignore

"Soft breasts mean low supply." Soft breasts mean a well-regulated supply.
"Pumping output equals breast output." Pumps are far less efficient than a baby. Don't use pump volume as a measure.
"You should feel let-down every feed." Many mothers stop feeling let-down after a few weeks. Feeding is still working.
"Top up with formula or supply will crash." Frequent removal of milk drives supply. Top-ups can reduce demand; speak to your MCH nurse or call the Australian Breastfeeding Association before adding regular bottles.

Quick-reference feeding card

Newborn: 8–12 feeds in 24 hours, on cue.
1–3 months: 6–8 feeds, with longer night stretches starting.
3–6 months: 5–7 feeds, possible feed-and-grow cluster phases.
6–12 months: 3–5 milk feeds + solids.
Free helpline: Australian Breastfeeding Association 1800 686 268, 7 days.
Log it: free Baby Tracker shows feed patterns at a glance.

Feed numbers will never look identical from one day to the next. Trust the pattern across a week rather than fretting about a single feed.

How much sleep does a seven-week-old baby need?

Most seven-week-old babies sleep for around 14–17 hours in 24 hours. This is usually divided between several daytime naps and short stretches overnight. Some healthy babies sleep a little more or less, so look at your baby's feeding, growth, wet nappies and alert periods as well as the total hours.

At seven weeks, the body clock is still developing. Day and night may remain mixed up, naps can last anywhere from a few minutes to a couple of hours, and waking every few hours to feed is normal. Many babies also become unsettled or want frequent feeds in the late afternoon or evening.

Follow your baby's cues

There is no need to enforce a strict sleep schedule. Offer sleep when you notice early tired signs, such as:

yawning or becoming quieter
staring into the distance
jerky movements or clenched fists
turning away from faces, noise or play
fussing after being awake for a while

Responding early can make settling easier. Feeding, cuddling, rocking or holding your baby to sleep are normal, responsive ways to support them at this age.

Keep every sleep safe

Place baby on their back for every sleep.
Use a firm, flat, level sleep surface with a well-fitting mattress.
Keep the sleep space free of pillows, doonas, cot bumpers, toys and loose bedding.
Keep baby's head and face uncovered and avoid overheating.
Have baby sleep in their own safe sleep space in the same room as a parent or caregiver.

Contact your maternal and child health nurse, midwife or GP if your baby regularly sleeps through feeds before weight gain is established, is difficult to wake, feeds less effectively, or has fewer wet nappies than usual. Seek urgent medical care if your baby is floppy, has trouble breathing, has blue or very pale skin, cannot be woken, or has a temperature of 38°C or higher. Call Triple Zero (000) for severe breathing difficulty, unresponsiveness or other life-threatening symptoms.
