A Little Summary…

Why Choose Baby Sleeping Bags?
Among the many benefits of baby sleeping bags is that they aid in keeping your little one at a consistent temperature through the night and day as they nap.
At the same time, they also allow for plenty of wriggle room without being restrictive, and more importantly, without posing the risk of getting tangled up or smothered with layers of baby blankets.

Baby Sleeping Temperature Guidelines
First of all, it’s good practice to monitor the temperature of the room your baby sleeps in, and especially important when it comes to choosing the correct tog sleepwear.
Sleep experts recommend 16-20°C as the ideal baby room temperature when it comes to sleep.
Babies under 12 months are more vulnerable when it comes to overheating, so be sure to adjust temperatures in your bedroom accordingly when you’re little one sleeps by your side in their crib or Moses basket. Having a thermometer handy is always a good idea, no matter the season.
How to Choose the Right Tog Sleeping Bag for Your Baby
The tog rating of the baby sleep bag acts as a guide to how warm the sleeping bag will keep your little one.
As you can see from the image guide above, the right tog for your baby will completely depend on the climate.
For a quick run-down, remember:
- 2.5 tog is ideal for use all year round for temperatures anywhere between 16-20°C (61-68°F)
- 1.0 tog is recommended for warm summer temperatures between 21-23°C (69-74°F)
- Anything lower than 1 tog is what you'll need when things really start to heat up, anywhere between 24-27°C (75-81°F)
When picking your sleeping bag tog, it’s important to understand that the higher the tog, the thicker the material and lining of your baby’s sleeping bag will be.
With this in mind, it’s handy to have a few different tog rated sleeping bags to hand in varying sizes so you can cycle them throughout the year, along with spares to account for any night-time accidents.

In their first six months, your baby should always be sleeping in a Moses basket or crib in the same room as you for safety reasons.
Of course, it's always recommended to check in on your little one as they sleep, regardless.
If you want to check their temperature specifically, aside from gently placing a thermometer beneath their armpit, you can also place a hand delicately behind their neck to check whether they're too warm.
If it feels damp or warmer than usual, consider removing layers to regulate their temperature until they're comfortable.
What Should Your Baby Wear Under a Sleeping Bag?
The tog rating of a sleep bag is super important when it comes to figuring out what your baby should wear to sleep comfortably and safely.
- For example, a 2.5 tog sleep bag is perfect for cooler rooms (16-20°C) and pairs well with a long-sleeved bodysuit or sleepsuit.
- If your baby's room is a bit warmer (20-24°C), go for a 1.0 tog sleep bag with lighter clothing, like a short-sleeved bodysuit.
- And for those really warm nights (over 24°C), a 0.5 tog sleep bag with just a vest should do the trick.
The goal is to help your baby stay at a comfy temperature and get a good night’s sleep. Always keep an eye on the room temperature and adjust their clothing as needed!

What Sleeping Bags are Best for Baby?
As well as the sleep bag tog, there are other points you want to consider when picking the best sleeping bag for your bubba.
Material (Cotton is Best)
Material is one of the most important. Anything low-quality or scratchy is a given no-no, as this can irritate your baby's supple skin.
Cotton is the best and safest material because it’s soft, breathable, and helps with safe temperature regulation.
The Little Green Sheep sleeping bags are made with cotton for exactly that reason.
The organic cotton we use to craft the outer layer of our sleep bags is blended with luxurious linen, creating a comforting, natural, and hypoallergenic sleep environment.
The quilted design also helps to keep the fill evenly distributed and makes for an even cosier sleep bag.
Nappy Change Features
When your baby is all cutely wrapped up, you want to disturb them as little as possible when they need changing. Sleeping bags with fastenings for easier nappy changes are a lifesaver for this.
Take ours, for example. Our sleeping bags feature a side zip, which means you can easily lay your baby down and change their nappy without having to fully remove the sleep bag.
Sizing Adjustments
While baby sleeping bags are available in various sizes, such as 0-6 months and 6-18 months, this is just a guide, and not all babies 0-6 months in size will necessarily fit comfortably into a 0-6-month sleep bag.
Sleep sacks with adjustable sizing features are great, as you can tweak the bag to fit your baby perfectly.
The under-arm poppers on The Little Green Sheep bags are an excellent and nifty feature; you can pop the fastenings in and out to ensure the bag fits your little one just right. This makes for a safer sleep environment and optimises the temperature regulation of the bag.
Beautiful Design
While safety and practicality are at the top of the list for importance, that’s not to say your baby’s sleep bags can’t still be beautiful! Thoughtfully and lovingly designed sleeping bags will also be available in a variety of colours, patterns and styles.
You can opt to match your baby’s sleeping bag with their crib or Moses basket bedding, which will create a really cosy-feeling room for your little one.
We have coordinating colours and patterns across our range of sleeping bags and fitted sheets, allowing you to create a beautifully pulled-together room aesthetic.
For example, our Dove Rice fitted sheet matches our Dove Rice sleeping bag perfectly.

Alternatively, you can mix and match these complementary tones, like pairing the neutral White Rice fitted sheet with the warm Honey Rice sleeping bag.
