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

The day-to-day signs

• Wet nappies: expect 6+ heavy wet nappies a day once feeding is established (fewer in the first few days is normal).
• Dirty nappies: regular soiled nappies, changing from dark meconium to yellow (breastfed) or paler (formula-fed) over the first week.
• Behaviour: reasonably settled after most feeds, though "cluster feeding" — bunching of frequent feeds, especially evenings — is normal and not a sign of low supply.
• Alertness and tone: generally alert when awake, with good muscle tone, not persistently floppy or difficult to rouse for feeds.

The number that matters most: weight

Some initial weight loss after birth is normal and expected. Most babies regain their birth weight by 2–3 weeks and then track along their own centile curve — not necessarily the average, just consistent. Your health visitor plots this at routine weigh-ins; a flattening or dropping curve is the trigger for extra support, not a single quiet day.

When to get help sooner

Fewer than the expected wet nappies, unusually sleepy/hard-to-wake feeds, ongoing weight concerns, or your own gut feeling that something's off are all good reasons to contact your midwife, health visitor or GP promptly — feeding support is widely available and most problems are genuinely fixable.
