By the way, if you want to look at winter-specific baby sleeping bags, we've got a whole article on them here.
Check out the list of the Best Baby Sleeping Bags in Australia:
What TOG Sleeping Bag Does My Baby Need?
One of the most important things to consider when choosing a baby sleeping bag is the TOG rating. TOG stands for Thermal Overall Grade and measures how warm a sleeping bag is. The higher the TOG, the warmer the sleeping bag.
Choosing the right TOG helps keep your baby comfortable overnight while reducing the risk of overheating, an important part of safe sleep guidance for babies in Australia. The best TOG for your baby will depend on the season, your nursery temperature and what your baby is wearing underneath.
TOG Rating | Best For | Recommended Room Temperature |
|---|---|---|
0.2 – 0.5 TOG | Hot summer nights | 24°C+ |
1.0 TOG | Mild weather and daytime naps | 20–24°C |
2.5 TOG | Standard Australian winter | 16–20°C |
3.5 TOG | Very cold climates and winter nights | Below 16°C |
Many Australian parents find the following appropriate for the different seasons:
0.2 or 0.5 TOG sleeping bags for summer
1 or 2.5 TOG for use in cooler months
3.5 TOG for colder states and winter overnight temperatures
Natural fabrics like organic cotton, bamboo and merino wool can also help regulate your baby’s temperature more effectively across changing seasons.
For safe sleep, always follow the manufacturer’s dressing guide and avoid layering your baby too heavily underneath their sleeping bag. Head to Red Nose Australia for more.
What Makes a Baby Sleeping Bag Safe?
Red Nose Australia recommends choosing a baby sleeping bag that is:
well fitted across the neck and armholes
a hoodless design
the correct size for your baby
appropriate for the room temperature and season
designed to allow unrestricted arm movement
has labels to advise on correct use and relevant safety information
A sleeping bag that is too large or too loose can increase the risk of suffocation or entrapment, while overly warm sleeping bags may increase overheating risk. Red Nose also advises against using weighted sleeping bags or products that restrict arm movement once babies begin showing signs of rolling.
1. Love to Dream Swaddle Up Sleeping Bag
Best for: Newborns and babies who like their arms up when sleeping.
Why Australian Parents Love It
One of the most popular baby sleeping bags in Australia, the Love To Dream Swaddle Up is designed to help newborns sleep more comfortably while supporting safer sleep routines. Its signature arms-up design allows babies to self-soothe naturally by keeping their hands near their face — a sleep position many newborns prefer.
The zip-up swaddle design also makes overnight nappy changes quicker and easier for parents, while the snug fit helps reduce the startle reflex that can interrupt newborn sleep. Designed in Australia, the Swaddle Up has become a go-to choice for many first-time parents looking for a simple and effective newborn sleep solution.
Fabric, TOG and Seasonal Suitability
Fabric, TOG and Seasonal Suitability
The Love To Dream Swaddle Up range is available in multiple TOG ratings, making it suitable for year-round use across Australian climates. Parents can choose lightweight 0.2 TOG and 1.0 TOG options for summer and warmer weather, as well as 2.5 TOG and 3.5 TOG styles for winter and cooler overnight temperatures.
Made from soft cotton-rich stretch fabric, the Swaddle Up is designed to feel snug and secure while still allowing healthy hip and leg movement. Organic fabric options are also available for parents looking for more natural fibres.
Fabric: Cotton-rich stretch fabric and organic options
TOG: 0.2–3.5
Best season: All seasons
Best age: Newborn, but there are other options like transition swaddles, sleep suits and sleeping bags for toddlers and older babies.
What Makes It Stand Out
What sets the Love To Dream Swaddle Up apart is its transition-focused sleep system. Unlike many traditional swaddles, the range is designed to support babies through different stages of sleep development, helping them gradually transition from swaddling to independent sleep.
The arms-up design is also frequently recommended by Australian parents in Reddit sleep discussions and parenting groups for babies who dislike having their arms wrapped down. Combined with multiple TOG options and an easy zip-up design, it’s become one of the most recognised baby sleep sack brands in Australia.
2. Woolbabe Duvet Front Zip Sleeping Bag With Sleeves, $199.95
Best for: Winter warmth and premium temperature regulation.

Parents especially love the front zip design, which makes overnight changes easier, along with the roomy fit that allows longer wear as babies grow. The soft natural fibres are also gentle on sensitive skin, making it a popular choice for babies who struggle with synthetic fabrics.
Fabric, TOG and Seasonal Suitability
Made from a blend of Australian merino wool and certified organic cotton, the Woolbabe Duvet Sleeping Bag is designed to help regulate body temperature throughout the night while still feeling warm and cosy. The duvet-weight construction makes it one of the warmest baby sleeping bags in the Woolbabe range.

Best age: 6 months to 4 years
3. Billie + Bobbie All Season Merino Wool Baby Sleeping Bag, RRP $219.95
If you’re looking for a safe and comfortable sleeping option for your baby, you can’t look past the unique features of merino wool, as found in the incredible Billie + Bobbie All Season Merino Wool Baby Sleeping Bag.
Did you know that Merino Wool features a myriad of benefits related to sleep and comfort? In fact, Research from the International Wool Textile Organisation has found that babies who slept with merino wool actually had a deeper, more restful sleep. Researcher Dr Paul Swan, from the University of Sydney, said: "Wool regulates your body temperature far better, keeping you in what is known as 'the thermal comfort zone'. You therefore not only fall asleep quicker, sleep longer, but also have deeper, better quality sleep."
Yep, you read right - more sleep. Billie + Bobbie Merino Wool Sleeping Bags are also available in an all season and winter weight, so you can choose the option that suits your home and the season.
Why Australian Parents Love It
The best thing about the Billie + Bobbie All Season Merino Wool Baby Sleeping Bag is the fact that it grows with your baby and that it is suitable for use across all seasons, compared to a regular TOG-rated sleeping bag, which you need to buy many, as they have to be switched around across the year to coincide with the temperature.
If you have a baby with sensitive skin, you’ll be pleased to know that Merino Wool is actually recommended for sensitive skin & eczema thanks to its ability to manage moisture levels next to the skin.
Similarly, Merino Wool can help to regulate temperature - a skill that babies can’t achieve on their own, meaning that the natural properties of Merino Wool allow it to create a microenvironment around the skin keeping your baby warm when it’s cold, and cool when it’s hot, maintaining the ideal temperature.
Merino Wool is luxuriously soft, light, and non-itchy which makes it the ideal fibre to wear against the skin. Billie + Bobbie Sleeping Bags are made using 18.5 microns of Superfine Merino Wool. ‘Superfine’ refers to the diameter of the fibre. Because the Merino Wool is so fine it feels soft against the skin, unlike traditional wool which can feel itchy or prickly.
Better still, all Billie + Bobbie Merino Wool Sleeping Bags are made right here in Australia, so you can be sure that you’re receiving a quality product every time.

12. Anchor & Arrow Baby Winter Sleeping Bags, $69.95
What makes Anchor & Arrow Baby Winter Sleeping Bag different?
When your baby has begun to roll and has outgrown their traditional swaddle, it’s time for arms out! Anchor & Arrow winter sleeping bag is a key part of your little ones' sleep routine; they associate this to be a cue for when nighttime comes and it’s time for bed. Lovingly designed in Australia, the Anchor & Arrow Sleeping Bags are the ultimate choice for establishing a strong bedtime routine, and ensuring your baby is warm and comfortable enough to sleep through the night.
Better still, the luxurious sleeping bags are made from premium materials that are soft and gentle on your baby’s skin. With no need for blankets, Anchor & Arrow Sleeping Bags have been designed to keep your little ones warm and safe as they sleep.
A baby sleeping bag is like a cozy cocoon your little one wears to bed — keeping them warm, secure, and safely covered all night long. Unlike loose blankets that can slip over your baby’s face, a sleeping bag stays in place while leaving their arms and head uncovered for safe breathing. They come in various thickness levels (TOG ratings) to match the room temperature, so your baby stays comfortable year-round. Many parents find that using a sleeping bag helps create a calm, predictable bedtime routine and encourages better sleep for everyone.
What your baby wears under their sleeping bag depends on the room temperature and the bag’s TOG rating. In warm weather (around 24°C or higher), a light cotton singlet or short-sleeve bodysuit is usually enough. When it’s cooler, you can layer up with a long-sleeve bodysuit or a footed sleepsuit for extra warmth. Always use breathable, natural fabrics like cotton to prevent overheating, and skip hats or extra blankets. The best way to check comfort is by feeling your baby’s chest or back — they should feel warm, not hot or sweaty.
Yes, baby sleeping bags are generally safe and can even help lower the risk of Sudden Infant Death Syndrome (SIDS) by keeping loose blankets out of the cot. To ensure safety, choose a sleeping bag that meets Australian safety standards, fits snugly around your baby’s neck and arms, and has no hoods, sleeves, or thick padding that could cause overheating. Always place your baby on their back to sleep and check that the bag’s TOG rating suits the room temperature for a comfortable, safe night’s rest.
You can tell if your baby is at a comfortable temperature by feeling their chest, neck, or back — they should feel warm and dry, not sweaty or chilly. It’s perfectly normal if their hands and feet feel a little cool. Signs of overheating include red cheeks, damp skin, or restlessness, while being too cold may show as pale skin or curling up for warmth. If needed, adjust your baby’s layers or the TOG level of their sleeping bag to suit the room temperature. A baby who’s comfortably warm will sleep more peacefully and safely.
To choose a newborn sleeping bag, prioritise safety, comfort, and temperature control. Look for a snug fit around the neck and shoulders to prevent your baby’s head from slipping inside. Ensure ample legroom to support natural hip movement. Choose soft, breathable fabrics like 100% cotton or bamboo for comfort. Match the TOG rating to your room’s temperature to prevent overheating, and opt for a machine-washable bag with a bottom zipper for easy night changes. Avoid bags with drawstrings or cords that could pose a safety hazard.
