Are you looking for the best baby sleep bags? We’ve got you covered.

Creating a safe and comfortable environment where your baby can sleep soundly can be tricky.

There are so many different products on the market it can be hard to know which ones are best for baby.

When it comes to kitting out the crib, many parents decide to invest in sleep bags — also known as baby sleep sacks — for their babies rather than regular blankets or duvets.

But what are baby sleeping bags and why are they a better choice than more traditional bedding?

Read on to find out…

What Are Baby Sleep Bags?

Baby sleep bags are essentially mini versions of adult sleeping bags.

Available in a range of different sizes, baby sleep bags don’t have hoods, and have openings for baby’s head and arms, yet can be zipped up right to the neck so baby won’t slip down inside the bag as this could lead to overheating or even suffocation.

It is claimed that when used correctly baby sleeping bags can reduce the risk of Sudden Infant Death Syndrome (SIDS).

Baby sleep bags are designed to stop baby from moving around too much or turning over during sleep. They are also designed to help keep baby at the correct temperature throughout the sleep period, as sudden temperature changes can disturb a baby’s sleep.

Just as baby sleeping bags come in a large range of sizes, they are also available in different togs (heat ratings) to ensure that baby sleeps in a sleep bag that is appropriate for the environmental temperature.

For example if it is hot or if your baby is wearing thick clothing, and in rooms with a temperature of around 20°C to 24°C, a lighter tog such as 1.0 tog is ideal, whereas in cold winter weather a thicker 3.5 tog baby sleep bag would be a better choice.

It is a good idea to buy sleep bags in a range of different togs so you are always prepared whatever the climate.

There are also many designs of baby sleep bag available, including travel sleep bags, brightly colored sleep bags, and organic sleep bags, as well as sleep bags with different zip placement designs.

Baby sleep bags should never be used with any kind of additional blanket as this could be dangerous, and they shouldn’t be used if baby is able to climb out of his or her crib.

Sleeping Bags vs Blankets And Duvets

Sleeping bags for babies have a few major advantages over traditional blankets and duvets. Let’s take a look…


Using a baby sleep bag ensure that baby stays at the correct temperature constantly, unlike with a blanket which can be kicked off during sleep and wake baby before the completion of his or her natural sleep cycle.


Blankets or duvets may get tangled up around baby’s limbs during sleep, or even cover their face, increasing the risk of suffocation.

Sleeping bags for babies are specially designed to keep baby’s head and arms free from getting covered or tangled up, yet allowing baby to continue move his or her legs and feet freely inside the bag.

Babies who use sleep bags are also less likely to turn over onto their stomachs at night, therefore reducing the risk of SIDS.

sleep sack vs blanket


With sleep bag, baby can more around more freely and still remain cosy and safe without mom or dad having to come and tuck them in every time he or she moves to much or kicks off the blanket.


Sleep bags aren’t just for bed or nap time, they are also very convenient for when you and baby are on the move.

Likewise if you are feeding your baby you don’t have to remove him or her from the sleeping bag when feeding time comes around, unlike a regular duvet or blanket.


Creating bedtime routines are very important for babies. Making a baby sleep bag part of this routine encourages baby to make the association between the sleep bag and peaceful sleep.

This can help baby drift off to sleep more easily, as well as making life easier for everyone when you are away from home or move to a different bed, as baby will automatically settle more easily.

Features Of The Best Baby Sleep Sacks

Whatever size of baby sleep sack your baby needs, it is vital that it is a good fit and features secure fastenings around the arms and neck to ensure that it won’t slip out of place.

Poppers are suitable for very young babies, but as they get older and more active these can become undone, so it’s best to choose a sleeping bag with zip fastenings for your baby.

Zips that open from the bottom to the top are best, as even in the event that they should come partially undone, baby won’t be able to wriggle out of the sleep sack easily.

Comfort is also a major factor, so it’s important that it is made from a soft, comfortable, and preferably breathable material such as natural cotton.

Never choose a baby sleep bag with arms or a hood as these features are potentially hazardous and are linked to SIDS.

An additional feature of the most practical sleeping bags for infants is that they can be securely attached to a car seat or buggy, making them ideal for travel.
