Prevent your baby's sleeping problems

When your baby doesn't sleep well, the whole family suffers. We know that better than anyone. In fact, Fedde&Kees was created because the youngest son of founder Frederieke had sleeping problems. That causes stress. Every child is different and unfortunately there is no perfect advice. Yet we have come up with a unique solution that works for many babies!

Why does my baby have sleeping problems?

Your newborn baby is still used to the tight and secure environment of your womb. The well-known fetal position is not so pleasant for nothing, even for adults. However, you should put a young baby in bed on its back to greatly reduce the risk of SIDS. To create a natural sense of security, you can tuck your child in tightly..

Once the maternity assistant is gone, tucking in tightly often becomes a challenge. Babies do not yet have control over their bodies and make a lot of uncontrolled movements, which quickly loosen the sheet. This provides more room to move, more unrest and comes at the expense of the sense of security that babies so badly need.

Preventing sleeping problems in your baby

Rest and regularity are very important for a baby. At least as important is the feeling of security. This is possible with a deep pressure sensation on and limitation of the body. A traditional (but quite intense) and well-known way to achieve this is by swaddling your baby.

At Fedde&Kees we have developed a friendly way to give your baby a deep pressure sensation, limitation and thus security. With the NUNKI sheet tucking in becomes child's play and your baby can no longer untie the sheets and mess up. The constant deep pressure sensation on the upper body provides limitation and security. Your baby makes fewer uncontrolled movements, so it can sleep peacefully.

Solving your baby's sleeping problems

Is your baby already having trouble sleeping? Chances are your baby craves security! You can achieve this by providing a deep pressure sensation and limitation to your baby. Swaddling seems to be the solution, but this is a fairly intense method with a few drawbacks. Swaddling is quite complicated and has to be done in the right way because otherwise you will hinder the development of the hips.

Another disadvantage is that you have to reduce swaddling between 4 and 6 months because your baby will start rolling over. Because the fine motor skills have not yet been developed, the arms often start mowing uncontrollably again and subsequent sleeping problems will return on their own.

If your baby is between 6 and 9 months old and the reduction of swaddling is not possible, the Fedde&Kees method offers the solution. For this we always recommend the combination of the NUNKI sheet and theBUNDI sleeping bag at. Together they offer a great way to phase out swaddling. The  NUNKI sheet is also suitable for older, restless sleeping children up to 3 years old.

    My 4 month old little girl used to toss and turn every night around 3/4 am and then continued tossing and turning. First night in the sleeping bag and under the sheet on it. I had prepared myself for a hellish night, because I thought she would have to get used to it, but she just slept through the night without waking up. What a fantastic product, can recommend it to anyone with a restless sleeper. And thank you, Frederieke, for the great service, your support and advice via Whatsapp!

    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

    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!

    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!

    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!

    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.
