How many clothes does a newborn baby actually need?

The ideal number of newborn clothes depends on daily outfit changes and your laundry routine.

We recommend quantities based on a 48-hour laundry cycle and 2–3 outfit changes per day.

Here’s the logic:

• Day 1:

  2–3 outfit changes (due to inevitable nappy leaks or milk spills)

• Day 2:

  Another 2–3 changes while Day 1's washing is in progress

• Safety Buffer:

  1 spare outfit for emergencies

This is why most essentials fall into the 4–7 item range - it ensures you're never caught short!

Growsuits (also known as onesies) will act as your baby’s daily uniform for the first few months of their life, simplifying dressing while keeping them warm and comfortable.

Cardigans: The Key to Safe Layering

Soft cotton cardigans are an essential layering piece for a newborn. Place over growsuits and long-sleeved tops in the cooler months, or over a singlet or singlet bodysuit on cooler summer days.

Muslin Wraps: The Multi-Use Essential Every Parent Needs

• Quantity:

  3+ units

  Swaddling, burping, pram shade

Hats & Mittens: Small Items That Make a Big Difference

• Quantity:

  2–3 sets

• Purpose:

  Prevent heat loss + protect skin

• When Needed:

  Especially in cooler weather or outdoors

Babies are born with an open fontanelle where heat can easily escape, so hats are a must for newborns. Our Knot Hats are perfect as the knot is adjustable, meaning it can be used as baby grows. Beanies are a warmer option for cooler months. Covering little hands with mittens will not only keep your baby warm, but also prevent any scratching from their fingernails.
