It’s the question that loops in every new parent’s head, and breastfeeding makes it louder: you can’t see milk go in, so “enough” feels invisible. The reassuring truth is that your baby keeps the receipts. Milk that goes in comes back out as wet and dirty diapers, shows up on the scale, and changes how your baby feeds and settles. You don’t measure the milk — you read the baby.
The signs it’s going well
None of these is a single pass-or-fail test; together they tell a calm, consistent story.
- Wet diapers. Six or more a day from about day five, with pale, nearly odourless urine.
- Weight. A dip in the first days, then steady gain — back to birth weight by around two weeks.
- Settling. Your baby relaxes, slows, or drifts off during or after most feeds.
- Alertness. Bright-eyed and responsive in awake stretches, with good colour and firm skin.
- Swallowing. During a feed you can hear or see a rhythmic suck-swallow once the milk lets down.
What “enough” weight looks like
Weight is the slow, honest measure — read over weeks, not days.
| Age | Typical weight pattern |
|---|---|
| First 3–5 days | Drops up to ~7–10% of birth weight — expected |
| ~Day 10–14 | Back to birth weight |
| 0–3 months | Gains ~150–200 g a week |
| 3–6 months | Gains ~100–150 g a week |
Regular weigh-ins plot this on a growth curve, and the trend is what matters — a baby tracking steadily along their own line is doing well, even on a lower curve. One number on one day tells you almost nothing.
During a feed: what “getting milk” looks like
Once the milk lets down, the rhythm changes: short, quick sucks give way to a slower suck–swallow–pause, and you can often hear a soft “kuh” of swallowing. A breastfed baby who has had enough usually comes off on their own, hands unclenched and body loose, and the breast feels softer than before. A bottle-fed baby takes it steadily with natural pauses and turns away when done — an emptied bottle every time is not the goal.
The things that make parents doubt — but usually don’t mean “not enough”
So much normal newborn behaviour gets misread as a low supply:
- Feeding often. Eight to twelve feeds a day is normal, and evening cluster feeding — especially around growth spurts at roughly 3 weeks, 6 weeks, and 3 months — is your baby ordering more, not a sign you have less.
- Short feeds. An efficient baby can finish in ten minutes.
- Fussing in the evening. The witching hour is near-universal and rarely about hunger alone.
- Waking at night. Expected, and not evidence of underfeeding.
With good diapers and steady weight, none of these on its own means your baby is going short.
When to check with a professional
Trust your instinct and reach out to your pediatrician, family doctor, or health visitor — the same day — if you notice:
- Fewer than 6 wet diapers a day after the first week, or dark, strong-smelling urine
- No return to birth weight by two weeks, or weight loss continuing past the first week
- A baby who is very hard to wake, very floppy, or feeding fewer than about 8 times in 24 hours
- Signs of dehydration: a dry mouth, a sunken soft spot, fewer tears, or unusual listlessness
- A baby who is consistently distressed and won’t settle after feeds
This is general information, not medical advice. Every baby is different — if something about your baby’s feeding worries you, ask the people who know your baby’s history.
In the end, “enough” is really two everyday receipts: how often your baby feeds and the wet and dirty diapers that follow. Keeping a shared log of both turns the 3am “is she getting enough?” from a worry into something you can actually see — and turns the clinic’s questions into answers instead of guesses.
