    I WAS SKEPTICAL, BUT IT WORKED!!

    We don't know what we are experiencing, but this sheet is truly magical! Our son only slept in our arms during the day and in the sling at night. It was nice to be so close to us, but it became increasingly difficult, both physically and mentally. Tried a lot but nothing helped. We ended up with this sheet. My son didn't like swaddling so I was a bit skeptical. But it works!! My son now takes several naps a day in his crib and last night for the first time he slept 4 1/2 hours in a row in his own crib. Without a sling. He protests a bit at first, but due to the pressure of the sheet, he surrenders. Highly recommended!!

    OUR LITTLE SON SLEEPS SO MUCH MORE QUIETLY

    Very happy with the purchase of the Fedde&Kees sheet. The first night with the sheet, our son slept so much calmer and therefore better. He also slept soundly all night long. He didn't wake up every so often, for example because he was waving his arms again. It is expensive to purchase, but we think it is definitely worth it!

    THE DESIGNER DESERVES THE NOBEL PRIZE:)

    We are very happy with this product! Due to the four months of sleep regression, we did not sleep through the night for nine weeks. Our daughter woke up five times a night, mostly because she kept rolling over and couldn't roll back. In addition, we couldn't put her down until she fell asleep in our arms. With this sheet we can put our daughter to bed and within five minutes she falls asleep independently. She can sleep through the night regularly again and when she wakes up, we never have to take her out again, but she can fall back asleep on her own after some closeness. Life saver!

    ENTERING IS NOW A EASY PIECE!

    Extremely satisfied with the NUNKI sheet!! Our son would constantly kick off the covers during the night and then wake up and start crying. He doesn't kick off the NUNKI sheet and now sleeps contentedly through the night. Shipping was super fast and the blanket is very easy to put on the mattress. Tucking is now also a piece of cake!

    NOW SHE SLEEPS MUCH BETTER!

    Good service. The product was delivered quickly after purchase and we are very happy with the NUNKI sheet. Every night our daughter would kick her sheets off, waking her up. Now she sleeps much better!

    IN 1 WORD FANTASTIC!

    We are really happy with the Nunki sheet!! Started using this from 2-3 months and still so happy with it. I really recommend everyone in my area who is pregnant or has a small one to buy this! In one word fantastic! And also super easy and quick to contact if there are any questions or problems. Really a great product!!

    Pity THIS DID NOT EXIST BEFORE

    Dear Frederieke, I would like to thank you for these great inventions. The combination of the sheet and the sleeping bag works great for our third son Reza. Switched from a swaddle swaddling cloth without any problem. He sleeps peacefully and through the night. Such a pity that this did not yet exist with his older brothers, because that would have helped us a lot at the time

    HE SLEEPS LIKE A ROSE

    Almost 3 years ago we were hopelessly looking for a solution for our son who couldn't sleep. Since he could already roll at 4 weeks, we were not allowed to swaddle. By chance we came across fedde kees, then still fairly new. After a call from Fredererique, we decided to purchase the NUNKI sheet and the BUNDI sleeping bag. It felt like our last resort. After 3 days of practice, our son slept like a baby!

    WHAT A FANTASTIC SHEET!

    Our little darling slept through quite quickly with the help of a swaddle sleeping bag from dream to swaddle (our little one likes to suck his hands). But he often woke up around 04.30 from his own wobbling. Then often lay completely slanted in the co sleeper. Now he has been going to the shelter for a few weeks and sleeping didn't really work anymore. Finally decided to give the NUNKI sheet a try. And I can say it works great! He sleeps through again and lies quietly! Highly recommended!

    WE ARE SO HAPPY WITH THE SLEEPING BAG AND SHEET!

    Our son woke up several times in the night (read every two hours). It's been going so well since the day before yesterday! First he slept from 23:00 to 05:00 and yesterday from 22:30 to 07:15. We love Fedde and Kees!

    VERY HAPPY WITH THE SHEETS

    Our daughter sleeps wonderfully under it! Loose sheets/tucking in is a thing of the past, she is always nicely tucked up. We had a small defect with 1 sheet, this was immediately resolved. Excellent service, nice contact. Keep it up, very satisfied.

The sleeping bag is a mild alternative to swaddling, which gives your child more freedom of movement. It's a lot easier for you too. No hassle with complicated cloths, but simply a sleeping bag with sleeves that you can zip up. Super simple and most effective in combination with the NUNKI sheet.
