Our round-up of the best baby sleeping bags

The SnüzPouch Baby Sleeping Bag was shortlisted for Best Bedding at the Mother&Baby Awards 2021

The SnüzPouch Rainbow Baby Sleeping Bag is super soft and comes in adorable designs. With under-arm poppers, a side zip, and an innovative nappy change zip on the front for quick changes with minimal disturbance, this is a safe choice.

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!"

At 2.5tog, and made from 100% cotton, this sleeping bag is machine and tumble drier safe.

With multiple useful features and adjustable sizing, this is a well-thought-through design. As well as having a zipper that fastens at the bottom to make night-time changes that little bit easier.

"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 sleeping bag can be adjusted for size via poppers, 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 1.5 tog, it will keep your little one comfortable all year around, although the brand recommends using 2.5 tog in the winter months. 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.

We love the character patterns available directly from MORI, such as the Peter Rabbit sleeping bag design pictured, they also do Peppa Pig and The Gruffalo!

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 and are lovely and soft. There is a two-way front zipper for easy nappy access. Ergopouch also do sleeping bags for once your child is past the swaddle stage and they're available in a wide rage of togs including lower togs such as 0.2 - ideal if your house gets quite warm or you're going on holiday.

Sleep when in the newborn stage can feel like an all-encompassing issue, but this sleeping bag may be of some help in catching some zzzz's. Newborns like to feel secure and the Purflo Swaddle helps to achieve that with an arms-zipped-in design that converts into an arms-zipped-out design once baby is a little older. 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.

The poppers on the arms means this sleeping bag is easy to transition between a swaddle bag and sleeping bag. It has a two way zip which makes getting baby in and out and nappy changes a breeze, and the flap covering the zip is secure to prevent any irritation from the zip.

The soft cotton material is comfy and the quilted padding makes it feel extra cosy. “It’s a small thing, but I like that the external label tells you what tog it is, it just makes life so much easier when grabbing a sleeping bag for bedtime.” 

Our tester also liked the fit of this sleeping bag, “Being a smaller size 0-3 months mean the fit is snugger and stops me worrying that it’s too big for my baby. Although it means buying more sleeping bags in the long run, I’d rather have this snugger fit, especially in the fourth trimester.”  

The skin friendly material is hypoallergenic, so gentle on babies skin even if they’re just in a nappy.

The material of this sleeping bag is lovely and soft, with a quilting to the front of the thicker 2.5 tog option (they do also make a 1 tog for summer). The zip fastens on the left hand side, at the top near baby’s arm and there is a fabric flap to cover the zip to prevent irritation. In terms of safety features, the addition of an extra popper at the arm holes is great to secure smaller sleepers, and there’s also a pair of poppers on each shoulder.

Our testers were impressed with the quality of the fabric, “I loved the softness of this sleeping bag, and the pattern was understated and neutral but different from the usual grey options for unisex designs. I love the ochre which is just as suitable for boys as it is girls.” 

However they did find the position of the zip made nappy changes a bit more of a challenge than with other sleeping bags, “Having tried other brands which have a front zip that opens from the bottom, I did find this zip a bit trickier to get at when my baby was stirring, if I was trying to check his nappy without him waking up completely.”

Something our testers thought could be improved upon was having a way to secure the flap over the zip, "Although my baby was in a sleepsuit as well I was a bit concerned the placement of the zip could rub him.”

Available in a range of neutral patterns, our favourite is honey rice, pictured below - you can also get matching bedding!

This is a versatile swaddle that can be secured in multiple ways, so ideal for babies who sometimes like to be swaddled with arms in, but sometimes sleep better with one or both arms out. The Velcro fasteners mean you can adjust it to your baby’s preferred fit, knowing they will be safe and secure all night.

Our dad tester said, “Especially with my newborn I found it reassuring to be able to wrap her in this, and that it wouldn’t come undone halfway through the night. She seemed to prefer the fit of a swaddle but I was always worried I was doing it wrong.” He adds, “Having this swaddle sleeping bag combo has given me peace of mind at bedtime.”

There’s a large stitched on label on one of the swaddle ‘arms’ that gives a breakdown of how to wrap the swaddle, so you have the instructions there and ready for you at all times, and it’s tucked away from baby when folded so you don’t have to worry about it irritating them, the soft micro-fleece material is all that touches them. 

Another tester added, “I liked that you could keep baby’s arms swaddled while checking the nappy thanks to the bottom zip.” There are lots of designs available, as well as plain colours. 

One potential con is that once your little one doesn’t want to be swaddled anymore the flaps become a bit redundant, but there’s no way to remove them, so you may end up having to buy a new baby sleeping bag.

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.

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.

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."

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.
