The baby sleeping bag is the essential childcare item for the birth of baby and until potentially... his 36 months... A little less for some, a little more for others... In any case it is recommended by early childhood specialists until 24 months!

When we conducted our market research, we realised that young parents generally owned about ten sleeping bags... 😱 and that's not possible for "consume less but better" enthusiasts. Opting for a "real" 4-season baby sleeping bag is a good solution to reduce the number of sleeping bags needed to a minimum. And even better: opt for an upgradeable 4-season sleeping bag. We'll tell you all about it in this article!

What is a 4-season baby sleeping bag?  

A 4-season baby sleeping bag or all season sleeping bag is simply a sleeping bag that can be used all year round. This means that you only need one sleeping bag for all four seasons. How convenient is that? So you can of course vary the thickness of the sleeping bag depending on the temperature of the room and the season.

How is this possible? At Kokùn Lab, the 4-season sleeping bags are equipped with removable linings. You just have to remove or put back the liners according to the temperature of the room and the night clothes of your little koko.

It is very important that baby sleeps at the right temperature! For his well-being, of course, but also to reduce the risk of cot death. See our article « how to dress baby at night » for more information on this subject.

How do you measure the warmth of an all-season sleeping bag?

Have you ever heard of TOG (Thermal Overall Grade)? This is the heat index of a sleeping bag. It helps you to evaluate the warmth of a sleeping bag because a thick sleeping bag does not necessarily mean warm! These TOGs are measured by independent laboratories.

At the Lab, we have 2 heat ratings for our 4-season sleeping bags:

• Sleeping bag without removable liners: TOG 0,5
• Sleeping bag with removable liners : TOG 2,5

We advise you to use the 4-season baby sleeping bag with the 2 liners or without any liners. It is not recommended to use only one of the 2 removable liners. It is important that the warmth is well distributed around baby and it is the layer that covers baby that is insulating.

To find out more about this heat index called TOG, consult our article « what does tog mean ? »

What is the advantage of the 4-season sleeping bag 0-6 months?

Whatever the season and the temperature outside, you should pack a warm sleeping bag in your maternity suitcase. At birth your newborn baby has difficulty regulating its body temperature and it will need to be covered. So you take your Kokùn Lab 4-season sleeping bag 0-6 months and you think to take the removable liners. When you come back home, your baby will be able to regulate his temperature better, so if it's hot, you can remove the removable liners.

At the Lab, we offer this multi-season sleeping bag in birth size (0-6 months) for 3 reasons:

• The sleeping bag will fit in any bed you choose at the beginning: cot, cododo, bassinet...
• The sleeping bag has a reassuring and enveloping shape that reminds you of mummy's belly where baby was so comfortable
• Your little koko is so small at birth that the size of the sleeping bag must be perfectly adapted

And the little extra of the Kokùn Lab 4-season sleeping bag 0-6 months : you can hold baby's arms in the sleeping bag to avoid the jerks linked to the Moro reflex and to reassure your baby.

4-season sleeping bag: what else does it have?

It's already a great thing to only need one sleeping bag whatever the season. But the problem is that our little ones grow up at lightning speed... Young parents are often forced to buy a new sleeping bag every 6 months... At the Lab, we offer an upgradeable 4-season baby sleeping bag that accompanies baby from 6 months to 36 months.

What is the secret of our 4-season sleeping bag for 6-36 months? Thanks to a snap system, it can be adjusted at 3 important points to fit baby perfectly:

• At the neckline
• At the armholes
• In length

With the Kokùn Lab upgradeable 4-season sleeping bag, you are safe until the change to the duvet!

What are the advantages of choosing a multi-season sleeping bag?

• A real space saver in your cupboard!
• Less waste for the planet
• A practical sleeping bag for sudden and unfortunately increasingly frequent temperature changes
• No headaches! No need to run to the shop because baby is having a growth spurt
• An overall lower sleeping bag budget
• An ideal sleeping bag for travelling when the weather is uncertain
• Expecting a summer baby and your second baby will be born in winter? You can use the same sleeping bag...

So which all-season sleeping bag do you choose? The 4-season 0-6 months sleeping bag or the 4-season 6-36 months sleeping bag ?
