Why You Should Use a Sleeping Bag

Choosing the best sleeping bag for your baby or toddler can make the difference when it comes to getting more sleep. Sleeping bags are a safe sleep alternative to traditional blankets or bed sheets and a natural transition from a swaddle, when baby is old enough and ready to stop swaddling. Unlike sheets or duvets that can be wriggled under or pose a suffocation threat, the sleeping bag keeps your baby's face clear, whilst keeping their body warm, cosy and comfortable. A sleep sack can't be kicked off like a blanket either - so there's less chance of getting woken in the night because your little one has woken up cold with their covers on the floor. a

They are also a fantastic sleep association that let's a baby know that it's time to settle and sleep. Whether you decide a Merino, organic cotton or another fibre or filling comes down to your baby's requirements, the season & room temperature as well as your personal preference.

How many sleeping bags do you need? We recommend you invest in 2 sleeping bags for your baby or toddler. This is particularly important in winter, when washing takes longer to dry and also you really need your sleeping bag to keep your baby warm. If your little one goes to daycare then it's a good ideas to get at least one for home and another for daycare. 

We have dozens of baby sleeping bag options to choose from in our range to suit most budgets & styles. We hand pick the best, test them thoroughly and if a sleep sack doesn't meet our standards and criteria it doesn't make the cut.

If you are currently swaddling you'll want to check out our articles on transitional swaddles and weaning your baby off swaddling to a sleeping bag click here for more.

Tog Ratings & Warmth Guides For Sleeping Bags

baby in sleeping bag and bodysuit happy to see mum

Many sleeping bags use the European TOG rating system to indicate how warm the sleeping bag is and what season they are suitable for. The higher the TOG, the warmer the sleeping bag. 

The Tog rating describes the warmth or "Thermal Resistance" of a product and is widely used to explain warmth levels of duvets. Unlike duvets infant sleeping bags have lower tog rating numbers. It is rare to find a safe sleeping bag that is rated over 3.5 tog. For our climate and heated homes 2.5 tog is usually high enough although we have tog rated options up to 3.5 tog in some brands. Alternatively a Duvet Woolbabe (which isn't tog rated because it is made with Merino) is one of our wamest sleeping bags.

A number of external factors determine the tog rating of the sleeping bag that should be used. These include the quantity of clothing the baby is wearing, the temperature of the infant’s bedroom, the baby’s health and the amount of bedding necessary to keep an individual infant warm – this may vary as it does for adults. Check your baby regularly to ensure they do not overheat. 

Many sleeping bags that we stock come with a free nursery thermometer to help you select which tog baby sleeping bag to use and what sleepwear to put your baby in. 

The TOG indicates approximately how many blankets the sleeping bag is equivilent to. Bags with rating of 0.5 and 1 or below are for spring/summer use. Bags with rating 2-2.5 are for autumn/winter. 

Why are some sleeping bags tog rated and others are not?

Sleeping bags with polyester or man-made fibre fillings that can be consistently perform to a testing standard or set temperature range tend to be tog rated. In general sleeping bags made with Merino are not tog rated, as they are natural fibre which adjusts according to temperature, this is one of the reasons natural fibre Merino sleeping bags are so popular. Merino is also amazing a wicking moisture away from the skin. Woolbabe bags have the widest temperature range - the 3-seasons bag can be used for rooms 18-28 degrees, duvet weight bag can be used 14 to 22 degrees.

Is there a sleeping bag that can be used all year round in any temperature?

The short answer is no, not really. As the seasons change you'll need to adapt your baby's clothing and sleeping bag combinations to keep them comfortable to their room temperature. Most families find that they need at least two weights or togs of sleeping bag so that their baby doesn't overheat or become to cold at different times of the year. Scroll down to the table below to find a dressing guide for our most popular styles.

What to dress baby in at night

The warmth of the bag will vary enormously with what clothing you use inside the bag. You can easily add another layer of clothing to make the bag warmer, such as using an extra merino bodysuit. 

Using a room thermometer (eg gro egg) to accurately determine the temperature in your child's room is a good idea and will be a big help, particularly when it comes to choosing the clothing and sleeping bag combination for the temperature.

Many sleeping bags now come with a clothing guide in addition to a free room thermometer to help you decide which clothing combination to use. Use your common sense too, the clothing guides are just a starting point and you will still need to monitor your child and adjust their clothing and sleeping bag combination so that they are a comfortable temperature and don't overheat. Watch the videos above for further tips and advice.

Sleeping Bag & clothing guide

The guide below will help you to choose a sleeping bag that is suitable for the temperature of the room which baby will be sleeping in. Babies warmth needs vary for child to child just as they do for adults so use as a guide and adjust to suit your baby accordingley. Check your baby regularly to ensure they do not overheat or are waking up from being too cold. The optimal room temperature is around 18 degress celcius.  By adjusting the clothing that baby wears inside the sleeping bag you'll help to make baby more comfortable at different room temperatures. Try to keep baby's room temperature below 27 degrees so that they don't overheat. If the room temperature drops and baby is waking up from the cold choose a warmer weight sleeping bag. Sleeping bags like the Woolbabe are fantastic at adjusting to a wider range of room temperatures because of the use of naturally temperature regulating wool.

What size sleeping bag do you need?

Please choose the right size for your baby now, not for the future. While it may seem better value to buy something your baby will 'grow into', you risk buying something that is not safe now. With a sleeping bag that is too big, your baby may slide round inside it or slip down inside the neck.

Generally sleeping bags & sleep sacks are available in 0-6 months, 6-18 months and 18-36 months. Most Merino bags are available in 3 months to 2 years and 2-4 years. The actual size of the sleeping bag within each age range can vary, for example, some sleeping bags sized for use from newborn can be used up to 12 months in some cases where as other are shorter and may only fit up to a 6 month old. 

For more details on the sizing from our most popular brands click the link below. Remember to measure your child from shoulders to feet rather then head to toe. The measurements below are just for the most popular size range, other size options available in each of the styles.

Is a Front Zip Sleeping Bag Better than a Side Zip or Diagonal Zip?

We often get asked whether the front or side zip bag is 'better'....it's really hard to say, as our customers have different views on this!

We find a bag with front zipper is much easier to use - simply pop your baby in and zip down the front (zips end at the bottom). Bags with front zips don't have the hassle of babies popping the shoulder domes, generally have smaller arm holes which are a closer fit and have no risk of the domes failing after lots of use. It's still easy to change a nappy with a front zip, as they are plenty long enough and the bags open wide enough to access the nappy.

Shoulder domes and side zip enable you to open the bag out flat. This can be easier for babies under 6 months who still need frequent night nappy changes. With babies who sleep through the night the easier nappy change isn't really a factor.

Some bags have domes on both shoulders (eg Woolbabe & grobag) and when combined with a long side-zip can fold out flat for faster drying after washing, others have 2 domes on one shoulder only.
