How Many Wet Nappies Should a Baby Have? | Parenting Hub

Wet nappies are the most reliable home sign of hydration in babies. Here's how many to expect — newborn to toddler.

Wet nappies are the most reliable home sign that your baby is getting enough milk. Here's what to expect — and what to do if numbers drop.

First week

Roughly one wet nappy per day of life — day 1 = 1, day 4 = 4, building to 6+ heavy ones by day 5–7.

From day 7 onward

  • At least 6 heavy wet nappies in 24 hours
  • Pale or colourless urine, only mild smell
  • Disposable nappies should feel heavy with weight (3 tablespoons of water gives a sense of 'heavy')

What 'heavy' means

Modern nappies absorb so much it's hard to tell — tip in 3 tablespoons (45 ml) of water to feel a 'wet' nappy. Anything noticeably heavier than this counts.

When to seek help

  • Fewer than 6 wet nappies in 24 hours after day 5
  • Dark yellow or strong-smelling urine
  • Dry mouth, sunken fontanelle, no tears when crying
  • Lethargy, less responsive — ED now

Common questions

Hot day — fewer wet nappies, is that OK?

Offer extra feeds. If wet nappies stay low for more than half a day, see your GP.

My toddler is potty training — how do I track?

Track wees per day instead — aim for 5–6 in toddlers, with pale urine.
