Swaddles and sleeping bags keep babies safely warm without loose blankets in the cot. Red Nose Australia recommends sleeping bags from birth as the safer alternative to blankets, which can cover a baby's face or cause overheating. Our range covers stretch-cotton swaddles for newborns, wearable sleeping bags in different TOG ratings, transitional swaddles with arm options, and zip-front bags for easy nappy changes. Prices from $30, with most quality bags between $40 and $90. Stock is held across our Sydney, Melbourne and Brisbane warehouses, dispatching within 1–2 business days.
What's the difference between a swaddle and a sleeping bag?
A swaddle wraps a newborn (0–3 months) firmly to mimic the womb and stop the startle reflex from waking them. It restricts arm movement, which calms the baby into longer sleep stretches. A sleeping bag (also called a sleep sack) is a wearable blanket with arm holes — the baby can move their arms freely, the bag covers the body and legs. Babies move from swaddle to sleeping bag around 3–4 months, when they start rolling. Continued swaddling past the rolling point is a SIDS risk, which is why transitional swaddles with detachable arms exist — they ease the move from swaddled to arms-free.

Are sleeping bags safer than blankets?
Yes — Red Nose Australia and most paediatric sleep guidance recommend sleeping bags over loose blankets for babies under 12 months. The reasons are direct: a sleeping bag cannot cover the face during the night, cannot be kicked off (leaving the baby cold), and is sized to the baby so it cannot ride up over the head. Blankets in a cot are a known SIDS risk factor, particularly for under-6-month-olds. The trade-off with sleeping bags is the upfront cost — you need 2–3 bags in each TOG to handle the wash cycle — but they last longer than people expect, often through multiple babies if cared for.
Quick buyer's checklist
-
TOG rating: Match to your room temperature, not season
-
Size: 0–3m, 3–6m, 6–18m, 18m+ — sized to baby's height
-
Zip direction: Two-way zips open from the bottom for nappy changes
-
Arm holes: Sleeveless for warmer climates, long sleeves for cold
-
Fabric: Cotton or bamboo for breathability, fleece for cold rooms
-
Wash count: Buy 2–3 bags per TOG to cover the wash cycle
When do babies stop using sleeping bags?
Most children use a sleeping bag until 2–3 years old, when they transition to a duvet or doona. The cue is when the child reliably stays under a normal blanket without kicking it off — usually around the move from cot to bed. Some kids stay in sleeping bags until 4 or 5 because they prefer the feel. Sized sleeping bags go up to about size 4, so most kids age out of available sizes around then. The transition is easiest done in summer with a thin bag, then switching to a regular blanket on warm nights and adding it permanently.
How much do swaddles and sleeping bags cost in Australia?
Swaddles and sleeping bags at Simple Deals start from $30 for muslin swaddles and stretch wraps. Most TOG-rated sleeping bags sit between $40 and $90, with bamboo and merino wool bags running higher. All bags dispatch within 1–2 business days from our Australian warehouses.
What most sites won't admit
Almost every sleeping bag sold online in Australia is imported from China — including ours. The real difference is not where the bag is made, it's what happens after it lands in Australia. Marketplaces dropship straight from overseas containers, which is why "fast delivery" stretches into six weeks. We import in bulk, hold stock across our Sydney, Melbourne and Brisbane warehouses, and ship from there.
The other thing nobody mentions: room temperature matters more than season. The TOG charts on most product pages assume a baby's room is the same temperature as the rest of the house — but baby rooms often run 2–4°C warmer (closed door, less airflow) or cooler (north-facing, no aircon vent). Buy a cheap room thermometer ($10), check the baby's room temperature at night, and choose TOG accordingly. The seasonal label on the bag is a guide, not a rule.
Frequently asked questions
What if my sleeping bag arrives damaged?
Contact us within 7 days with photos. We will arrange a replacement or refund under the 12-month warranty. Transit damage is uncommon with packaged sleeping bags.
How often should I wash a sleeping bag?
Every 1–2 weeks for normal use, immediately after any soiling. Most bags machine-wash on cold or warm and tumble-dry on low. Check the care label — some require gentle wash only.
How long does delivery take?
Sydney, Melbourne and Brisbane: 3–5 business days. Perth and Adelaide: 5–8 days. Regional and remote areas: 7–14 days.
Can I pay with Afterpay, Zip or PayPal?
Yes, all three. A $80 sleeping bag works out to four payments of $20 with Afterpay, four payments of $20 with PayPal Pay in 4, or a small monthly amount with Zip. Klarna is also available.
What's the warranty?
12 months on manufacturing defects, plus 15-day returns on unworn items in original packaging.
Complete the baby sleep setup
A sleeping bag handles the warmth, and a few pieces complete the baby's sleep environment. Most parents add three at the same time: a cot for sleep, a night light for night feeds, and a baby monitor for the early months.
