Reassurance Starts With Watching Your Baby, Not Just the Clock
If you are breastfeeding, it is completely normal to wonder whether your baby is getting enough milk. You cannot see how much they are taking in, and unlike a bottle, there are no measurements to count. The good news is that your baby gives you plenty of evidence, and once you know what to look for, you can feel far more confident about what is going on.
The signs below are the ones midwives, health visitors and breastfeeding specialists rely on. No single one tells the whole story, but together they paint a very clear picture. If several of them are present, you can be reassured that feeding is going well. If several are missing, that is your cue to ask for help early, rather than waiting to see whether things improve.
Wet Nappies Are Your Most Reliable Daily Guide
Urine output is the quickest, most dependable indicator that your baby is taking in enough milk. In the first few days, expect roughly one wet nappy on day one, two on day two, and so on, building up to at least six heavy wet nappies in every 24 hours by around day five or six.
- Day 1: at least 1 wet nappy
- Day 2: at least 2 wet nappies
- Day 3: at least 3 wet nappies
- Day 4: at least 4 wet nappies
- Day 5 onwards: at least 6 heavy, soaked nappies in 24 hours
Colour matters as much as quantity. Pale, straw-coloured or colourless urine is what you want. Dark, strong-smelling wee, or the faint orange or pink stains known as urate crystals after the first few days, suggests your baby needs more milk. Nappies should feel satisfyingly heavy, not just slightly damp. If you are using reusable nappies, you may find it harder to judge, so check the weight and feel rather than relying on the look of the fabric.
Poos Tell a Story Too
Nappy contents change dramatically in the early weeks, and that progression is a sign in itself. The first poos are dark, sticky meconium. By around day three to five they should have shifted to a lighter green, then to the soft, mustard-yellow, seedy poos typical of a well-fed breastfed baby.
From about day five onwards, expect at least two to three generous yellow poos each day, and often more, sometimes one after almost every feed in the early weeks. A baby who is having plenty of wet nappies but very few poos may still be feeding well, but it is worth mentioning to your health visitor. After around six weeks, some babies naturally go days between poos, which can be perfectly normal as long as they are comfortable and gaining well.
Listening and Watching at the Breast
Feeding is not silent. When milk is flowing, you should hear soft, rhythmic swallowing, often described as a quiet "ca" or "kuh" sound, rather than just quick, fluttery sucking. Watch your baby's jaw: it should move in a deep, steady rhythm, with brief pauses and a wide-open mouth at the start of each suck.
You may notice your baby's chin touching your breast, cheeks staying full and rounded rather than dimpling inwards, and no clicking or smacking noises. Towards the end of a feed, sucking often becomes lighter and more comfort-led, which is normal and part of winding down. If feeding is persistently painful, or your baby never seems to settle into a steady rhythm, ask for a feeding assessment. A small tweak to positioning or attachment can change everything.
Weight Gain: The Longer View
Most babies lose a little weight in the first few days, usually no more than around 7 to 10 per cent of their birth weight, and then regain it by roughly two weeks. After that, many babies gain around 150 to 200 grams a week in the first few months, though every baby has their own pattern.
What matters most is the trend over time, plotted on your baby's growth chart, rather than any single weigh-in. Babies are not meant to follow a straight line exactly, and small dips can happen. If your baby is alert, producing plenty of wet nappies and gaining steadily overall, a single slower week is rarely a cause for concern. Your health visitor is the best person to interpret the chart with you.
How Your Baby Seems After a Feed
Contentment is not a perfect science, but it is genuinely useful. Many babies come off the breast relaxed and floppy, with open hands and a dreamy expression, sometimes falling asleep. Others feed frequently in the evening, cluster feeding for hours, which is normal and helps build your supply.
Some babies are naturally fussy regardless of feeding, and some will want to feed again within twenty minutes. That is not automatically a sign of low milk. However, a baby who seems constantly unsatisfied, never settles, or is too sleepy to feed at all needs a check. The number of feeds matters too: most newborns need at least eight to twelve feeds in 24 hours, including at night.
Trust Yourself and Ask for Help Early
You know your baby better than anyone. If something feels off, that instinct is worth acting on, even if the nappy count looks fine. Speak to your midwife, health visitor or a breastfeeding specialist if you notice fewer wet nappies than expected, dark urine, weight concerns, painful feeding, or a baby who is hard to rouse. Support is there for exactly this reason, and getting it early makes a real difference. Feeding well is not about doing it perfectly, it is about noticing the signs and getting the right help when you need it.
