Simple, neat tucking in with NUNKI
Swaddling tightly provides that safe and snug feeling your baby knows from the womb. Without maternity support, however, this proves to be a challenge. Babies have no control over their bodies yet and quickly kick off a swaddle. The NUNKI swaddle fits around the mattress, so it cannot come loose.
Tuck it in snugly by simply zipping it up. Anyone can do it and everyone does it the same way. This is how you create the ideal bedtime ritual for your baby. Our NUNKI sheet has not won two Baby Innovation Awards for nothing.
BUNDI: the ideal all-in-one sleeping bag
Our unique soft sleep bag has zips under the sleeves. With the zips closed, it's a gentle alternative to swaddling. Your baby can still move, but no longer flail their arms. This way, you can decide how much freedom of movement your baby has for each nap. The zips are also ideal for gradually weaning from swaddling: by opening the zips a little further each nap, your baby slowly gets used to more freedom of movement.
Safely tested - Let your baby sleep safely
Babies are vulnerable and still need to find their place in the world. There are all sorts of baby products that help with this, but have they been tested and are they safe?
NUNKI contributes to the four safe sleep recommendations.

TOG rating
NUNKI Cot Sheet: 0.5 TOG
BUNDI sleeping bag: 0.3 TOG
0.8 TOG
Thanks to the light design, you can use the products year-round as a base. We recommend always choosing bedding with a low TOG rating. Every baby reacts differently to temperature and not every room in the house is the same. It is easier to add warmth (winter) than to remove warmth (summer). To add warmth, simply place a blanket over the NUNKI sheet. Caution! Ensure your baby does not get too warm. Check this regularly by feeling the neck and the feet. The skin should not feel clammy or cold.
Hints
NUNKI
If you like, you can always send photos of the made-up sheet with the zip closed, without the duvet. Preferably one with and one without your little one.
Then I can have a look with you to see if you are going to use the sheet optimally from day 1.
Send the photo to klantenservice@feddekees.nl
The BUNDI sleeping bag can also be used once your child is able to roll over.
Even if your baby can already roll over, the Fedde&Kees method is safe. The sheet delays the moment they roll over, allowing you to use the BUNDI sleeping bag for longer. Most babies who can roll over are strong enough to push themselves up onto their tummies, even with the zips of the BUNDI sleeping bag lowered. Here is an example of a 5-month-old baby:

Always test in the cot to see if your baby is strong enough. If not, we recommend not using the zips anymore. Can your baby already roll over? Then Fedde&Kees advises to only use the sleeping bag in combination with the NUNKI sheet. If you are unsure about your situation, please contact us. Contact Meet us.
