Few questions nag at a new parent quite like this one: is my baby actually getting enough? Breasts don't come with a gauge — but your baby gives you plenty of signals. Let's walk through the ones that matter.
The big four signs
You don't need to track every millilitre. Health services across Australia (ABA, Raising Children Network), the US (AAP) and the WHO all point to the same handful of everyday signs:
- Wet nappies — lots of them, with pale, mild-smelling wee.
- Dirty nappies — regular poos in the early weeks (this can change later, more below).
- Weight gain — steady growth along their own curve over time.
- Behaviour and swallowing — your baby feeds with rhythmic sucking and audible swallows, comes off looking relaxed, and is generally alert and rousable when awake.
Wet and dirty nappies
Nappies are your simplest daily evidence. In the first few days the numbers are small and ramp up as your milk comes in. Disposables hold more, so the counts differ: AU sources suggest at least 5 very wet disposable nappies, or 6 or more wet cloth nappies, in 24 hours once your milk is established.
| Baby's age | Wet nappies (per day) | Poos |
|---|---|---|
| Day 1–2 | 1–2 | Dark, sticky meconium |
| Day 3–4 | 3–4 | Changing to greenish-brown |
| Day 5+ | 5+ very wet disposables, or 6+ wet cloth | Soft, yellow, often 3+ a day |
| After ~6 weeks | Plenty of heavy wet nappies | Can range from several a day to one every few days |
A useful trick: a properly wet nappy feels like 2–3 tablespoons of water poured onto a dry one. After the first 6 weeks, breastfed babies can go several days between poos and still be perfectly well — that's normal and not constipation as long as the poo stays soft.
Weight and growth
Most babies lose a little weight in the first days, then regain their birth weight by around 2 weeks. After that, steady gain along their own line on the growth chart is what counts — not hitting a single magic number. Your child-health nurse or GP will weigh and plot this at check-ups. One-off home scales can mislead, so try not to weigh obsessively.
Feeding is on track when...
- Active feedingDeep, rhythmic sucking with pauses and audible swallows.
- SettlesContent and relaxed after most (not necessarily all) feeds.
- Alert when awakeBright, rousable, with good muscle tone.
- GrowingFollowing their own curve over weeks, not days.
What about cluster feeding?
Frequent feeding — especially in the evenings or during growth spurts — is normal and usually a sign of a baby driving up supply, not a sign of too little milk. Counting feeds is far less reliable than counting nappies and watching your baby. If feeding is constant and nappies have dropped off, that's worth a check.
A gentle reassurance
When to get help today
Trust your instincts. If something feels wrong, it's always okay to ask. Contact your GP, child-health nurse, or a breastfeeding helpline if you notice:
- Far fewer wet nappies, or dark, strong-smelling wee
- No weight gain, or ongoing weight loss after the first week
- A baby who is hard to wake, floppy, or too sleepy to feed
- Feeding that's consistently painful, or you're worried about supply
A note on regions
Guidance on the everyday signs of enough milk is remarkably consistent worldwide. Some related advice does differ — for example, vitamin D supplementation recommendations vary (the AAP advises a daily supplement for breastfed babies, while in Australia it's usually targeted to babies with specific risk factors). Check what applies to you with your GP or child-health nurse.
