Winter Nursery Setup Australia & NZ: Creating a Cosy, Safe Sleep Space (2026)

Cosy winter nursery with organic cotton blanket and fitted sheet on a white cot — safe, warm sleep space for newborns

Setting up a nursery for winter is a different exercise to a general setup. The challenge isn't just aesthetics — it's function. A beautiful nursery that gets cold at 2 AM, or one so heavily layered your baby overheats, works against you.

This guide covers the practical elements of a winter-ready nursery: from temperature management to bedding layers to the products that make it work across the colder months.

Get the Room Temperature Right First

Before any product decision, get the room right. Red Nose Australia recommends keeping a baby's sleep environment between 16°C and 20°C.

For most Australian homes in winter, this means:

  • A digital room thermometer — inexpensive and removes all the guesswork
  • Consistent heating on a low overnight setting if available (ducted is preferable to portable heaters near the cot)
  • Closed windows and a door slightly ajar, rather than a fully sealed or fully open room

The goal is a room that feels cool-but-comfortable to an adult in a light layer. Consistency matters more than warmth — temperature fluctuations make settling harder.

Bedding in the Right Order

Step 1: Fitted Cot Sheet

Loose sheets bunch, shift, and create risks. A properly fitted woven cotton sheet creates the safe, smooth foundation for all layers above. Our fitted cot sheets are cut for standard AU/NZ cot mattresses (132 x 72cm):

Step 2: For Newborns — Swaddle

For babies under 3 months who aren't yet rolling, a swaddle is safer and more effective than a sleeping bag. Our Organic Muslin Swaddle in Elephant is GOTS-certified with a breathable open weave — warm enough for winter nights without the overheating risk of heavier fabrics.

Step 3: TOG-Appropriate Sleeping Bag (3 months+)

For winter in Australia (16–20°C rooms), a 2.5 TOG sleeping bag over a long-sleeve bodysuit is the right combination for most babies. TOG quick guide:

Room Temperature Recommended TOG
24–27°C 0.5 TOG
20–24°C 1.0 TOG
16–20°C 2.5 TOG

Step 4: Top Blanket if Needed

A light organic cotton blanket, tucked firmly to chest height with arms free, adds warmth without risk when used correctly. Our Organic Cotton Knitted Baby Blanket in Heart and Koala Minky Blanket Set are both well-suited to this role.

A Note on Nursery Heating Safety

Portable heaters near the cot are a risk — both for fire safety and for creating uneven heat near the baby. If heating is needed, ducted heating on a low, consistent overnight setting is the safest approach. Keep any heat source at a safe distance from the cot and bedding.


A winter nursery done well is warm enough to be comfortable, safe enough to protect against both cold and overheating, and simple enough that you're not adjusting layers at 3 AM.
