Typical peeing patterns

How often does a baby pee?

A normal baby will increase the number of pees daily during the first week of life. After this time, they tend to pee about six to eight times each day. Severe underfeeding or illness can result in fewer pees.

A) Normal peeing patterns

During the first week, the number of a baby’s pees each day increases as the amount of milk increases:

  • Day 1: 1 time
  • Day 2: 2 times
  • Day 3: 3 times
  • Day 4: 4 times
  • Day 5: 5 times
  • Day 6 and up: 6 – 8 times each day

Pees should be pale yellow in colour.

B) Using pee patterns as signs of underfeeding

Some mothers worry about how much milk a baby is taking in. Counting the number of pees each day is not a very helpful measure of this as only severe underfeeding as with a sleepy or starving newborn, will significantly decrease the number of pees.

Rather, babies who are getting some milk but not quite enough continue to pee relatively well. They will however, show other, more sensitive signs of not getting enough milk.

It can be difficult to assess pees if your baby is using disposable diapers.

C) When to be concerned

The number of pees will decrease and the pees will be darker if the baby is dehydrated and:

  • An underfed newborn.
  • Sick and only taking in very small amounts of milk.
  • Losing large amounts of liquids by vomiting or because of diarrhea.

Pee colour may change if the baby is sick.

A baby with a bladder infection may cry when peeing or show other signs of illness.
