Our round-up of the best baby sleeping bags

best baby sleeping bags

Baby sleeping bags are an alternative to blankets, designed to stay on your little one through the night even when they're wriggling about in their crib or Moses basket. Until your baby is approximately a year old, it's important to ensure that their cot is free from any items such as loose blankets, pillows and toys - including their favourite stuffed animal, where possible - as these items increase the possibility of accidental suffocation. Sleeping bags are the perfect substitute for blankets, keeping little ones cosy and safe all night long and encouraging them to feel secure when in bed (perhaps with the added help of sleeping aids!).

Not all sleeping bags are created equal, however, so make sure you look closely bat the features of each to decide what’s best for you and your little one. Some allow access to the car seat harness so are useable on car journeys. Others have easy access zips that mean nappy changes in the night are made easier. And don’t forget to check the thickness or tog rating, which will indicate the level of warmth it provides.

There are lots of things to consider, but the right baby sleeping bag can be a great investment. Read on for our round-up of some of the top-rated sleeping bags on the market, then check our FAQs below for more helpful information.

Sleeping with arms up is a natural position for babies and this sleeping bag supports that with its clever wing design. Arms are kept as snug and warm as the rest of the body within the stretchy jersey fabric, and nappy changes are made easy by a two-way zip.

These sleeping bags come in four sizes and will cater for your baby from newborn age through to 24lbs. With a huge range of colours and patterns to choose from, your little one can also set their style credentials early.

"I'm very happy using the Swaddle Up with my newborn, and have even purchased in the next size up," said one reviewer. "The material is nice and stretchy. It's easy to get on/off and I like that my baby's hands are covered so that he can't scratch himself even when he's not wearing scratch mitts. Also, the arms-up position seems to be comfortable for him."

As all parents will be glad to hear, The Swaddle Up is machine and tumble drier friendly, and won't lose its shape in the wash.

Pros

  • Unique patented wings for natural arm positon
  • Certified hip healthy
  • Twin zipper for easy nappy changes
  • Keeps arms warm as well as the rest of the body

Cons

  • No tog reference but listed as ideal for rooms between 20-24 degrees celsius
Tog:N/A, but listed as ideal for rooms between 20-24 degrees Celsius
  • Easy swaddle

Best baby sleeping bag with detachable sleeves

Catering for babies from newborn through to 24 months with three available sizes, the Kumala Cotton Muslin sleeping bags are a great option for between-seasons because of their removable sleeves. This 3.5 tog design allows parents to choose whether to keep their child's arms padded and warm, or take the sleeves off via a simple press-stud attachment on warmer nights.

"This sleeping bag is perfect for winter for my little one," said one reviewer. "The arms are detachable, so you can remove them for the warmer months. The fabric and quality of this is lovely. Would definitely recommend."

The fabric is 100% cotton. Available in seven colours and easy to throw in the wash and tumble dry, the only gripe some reviewers have is with the zip which they say is not easy to manage, particularly in the night when managing a nappy change. The zip runs along the side and feet of the sleeping bag.

Pros

  • Detachable sleeves
  • zip runs down the side and along the feet for easy access
  • Three sizes cater for newborn-24 months
  • Seven colours available

Cons

  • No built-in scratch mitts
  • The zip is difficult to fasten according to some reviews
Tog:3.5
  • Removable sleeves
  • Press stud shoulder
  • Colour variety

Best short sleeve baby sleeping bag

Price: $49.95

There's a surprising amount to say about this sleeping bag, but the main thing is that it converts from an arms-in design that helps baby feel secure in a swaddling position, to an arms-out design for when they are slightly older. Available in different tog ratings for different seasons - and the option to buy coordinating sleepsuits with padded sleeves - all your baby sleepwear and bedding needs are covered.

"My baby absolutely loves the cocoon swaddle bag, " said our own Mother&Baby reviewer Katie. "It’s simple to use and she sleeps so much better than before. She would regularly twitch and wake herself but she hasn’t since we’ve been using the swaddle bag, allowing us both to get a better nights sleep. I can quickly swaddle my wriggling baby in no time with the handy zip feature which is also great for nappy changes during the night. It’s perfect for taking to stay at her grandparents house with no need for blankets. I would definitely recommend to all new parents!"

Made from organic cotton and bamboo, and dyed with natural water-based dyes, the materials used are gentle enough not to aggravate sensitive skin. There is a two-way front zipper for easy nappy access.

Best natural baby sleeping bag

Price: $67.50

With multiple useful features and adjustable sizing, this is a well-thought-through design. As well as having a double direction zipper to make night-time changes that little bit easier, this sleeping bag as a pushchair belt opening so your baby can sleep warm and undisturbed whilst on the move and then be lifted straight into bed on arrival.

"We love these sleeping bags, our son has been using them from around 6 months, and I just got another one because they're just so good," said one reviewer. "He has never been able to get himself out of it (yet!) and they're super cute, too."

Designed for babies from 4kg through to 24 months, the Clever Sleeping Bag is adjusted for size via poppers for leg length and arm width, ensuring the sleeping bag is a secure fit and doesn't ride up and cover your baby's face. It's not recommended for babies under 4kg in weight.

At 2.5 tog, it will keep your little one comfortable and warm in the chillier seasons. It's made from organic cotton and bamboo fabric, breathable and thermoregulating materials that will help keep your baby or toddler at the ideal temperature.

  • Travel pushchair belt opening
  • Double direction zipper and side shoulder opening
  • Made from organic cotton and bamboo fabric
  • Can be adjusted for size to cater for 4kg to 24 months old

Cons

Best baby sleeping bag for summer

This two pack of organic cartoon sleep bags has a double zipper design for convenient changes in the middle of the night. The Lictin Baby Sleeping bags are a lighter tog for the warmer weather at 0.5, and are made from breathable 100 per cent cotton fabric. Available in two sizes, each is adjustable in length so they extend over time with your baby's growth.

The smaller size is for 3-18 months, the larger for 18-36 months. Many sleeping bag designs only cater to 24 months so these have a little extra longevity.

"Great value - two baby sleeping bags for the price you can pay for just one!," said one reviewer. "The material is soft and thin so perfect for summer nights for the baby. I’m no expert with tog ratings but these feel more like my baby’s 1.0 tog sleeping bags than 0.5. Either way they’re not thick with padding and are definitely suitable for baby sleeping in warmer conditions. The designs on the sleeping bags are lovely. Even nicer than they look in the picture. The double zip is very handy, as are the poppers under the arms so the arm hole size can be adjusted depending on size of baby. My baby is just over 6 months and the whole sleeping bag fits nicely. I do the poppers up for him so the sleeves aren’t too big. I’d recommend this product."

Pros

  • Ideal for warm weather
  • Lightweight at 0.5 tog
  • Dual zips
  • Two sizes cater from 3-36 months
  • More affordable than many other options

Cons

  • Some complained the zip cover wasn't big enough to cover the zips
Tog:0.5
  • Designed for summer
  • Zip fastening
  • Sleeveless

Best baby sleeping bag for easy nappy changing

Our own Mother&Baby tester said, "Yes yes yes! It’s so easy to change your little one without a fuss, just unzip and off you go! My little one never really woke up and it was so easy to fasten back up as quick as I unzipped! It’s easy to get on without a fuss and comfy for my little on and also cosy and warm so you don’t worry about the temperature in the night!"

"I've religiously bought Mori sleeping bags because I was told they were the best, but they're so overpriced and with the growing rate of most babies it wasn't sustainable," said one reviewer. "These sleeping bags are gorgeous, so soft and cosy with plenty of room for growth. More expensive doesn't mean the best - clearly! I'm looking forward to winter for my little man to sleep in this.

Price: $54.95

The Love To Dream Sleeping Bag is like a onesie-blanket for babies and toddlers. It also comes with optional feet covers to keep those little toes cosy and warm, or cool depending on the weather. The feet covers are helpfully gripped underneath for toddling before and after sleep. This one is designed for warmer weather and is sleeveless, but there are sleeved options available from this brand, too.

"Bought as my little one was refusing sleeping bags but would kick off blankets and wake up in middle of the night," said one reviewer. "Sleep suit kept him warm all night. Lovely and soft. Little one loved the pattern and kept telling me how cosy he was. Design still stops him climbing out of his cot (for now)."

Made with organic cotton and elastane, these are super soft and comfy to sleep in as well as to move in. They also have a lighter, upper chest fabric so that your little one can help regulate their temperate better. On the expensive side, these are particularly useful for for toddlers who are between the sleeping bag and blanket stages and also want the freedom to crawl and toddle. Available in five sizes.

It also features mesh panels to help regulate temperature and access at the bottom of the bag for nappy changes in the night.

"Very impressed with this swaddle to sleep bag," said one reviewer. Baby has been sleeping well in the for the past few days. I particularly like how versatile it is, lasting to 4 months with a few clever poppers at the shoulders & feet. The breathable panels to avoid overheating & stop sweating are fab! This is by far the best, when I compare to other big brands I have tried."

The Purflo features a loose leg design which enables use in a car seat and means parents can transfer a sleeping baby straight to the cot.

Baby sleeping bag FAQs: All you need to know

Are sleeping bags good for babies?

Yes, and in fact, they've been recommended by The Lullaby Trust as a sleeping product you can trust that can help reduce the chance of sudden infant death syndrome (SIDS).

Baby sleeping bags are a great option that'll keep your little one feeling snug and comforted at night. They prevent their head from being covered by wriggling, a risk that comes with blankets or sheets.

Things to consider when buying baby sleeping bags:

There are plenty of options available to buy, but there are certain characteristics you should look out for to ensure your baby sleeps safe and sound.

Size: There are different sized sleeping bags for different baby ages. This is a helpful guideline but you should make sure that the sleeping bag fits well around their shoulders. So that their head doesn't run the risk of slipping down into their bag.

Tog: To keep your baby at the best temperature, you can also get options with different togs for different seasons. A 2.5 tog is the most popular and will work well for most of the year. But, you could benefit from buying 0.5 to 1.5 tog sleeping bags for warmer nights and for the height of summer.

Comfort: Alongside this, you can consider different fastening options, cute designs, and natural fibre materials for softness and comfort.

Feet: Most sleeping bags will have be designed to keep your little ones feet tucked up inside, however some may come with the option to go footless. Footless sleeping bags may be better for a toddler, as they will allow them to move more freely.

How to wash a baby sleeping bag

Now that you've invested in the perfect sleepwear for your baby, it's time to get down to the nitty-gritty of how to clean it. First things first, you want to check the garment care label for any special washing instructions like hand-wash or to be cleaned in cold water only.

From there, we'd suggest using a non-bio detergent which is gentler on your baby's sensitive skin. For more advice on temperature recommendations and whether or not you can use fabric softener, read our guide to washing baby clothes.

How many options do I need?

There's no right or wrong answer to this. Here at Mother&Baby, we'd recommend having at least three options that fit your child. Why? Well, we'd advise having all these options tucked away in the nursery in case you're washing one and your little one goes on to have an accident - you can thank us later for having a backup.
