Why conventional pacifiers harm babies – and how two young founders found the solution that parents have been searching for so long

When you hear Paul talk about his invention today, you immediately notice that this is not a typical founder at work. Not a marketing professional, not a salesperson – but a father who wanted to solve a real problem.

“I remember it clearly,” Paul says, as he looks at an old video of his son. “The little one constantly had the pacifier almost completely in his mouth. Once he choked so badly that my heart stopped for a moment.”

What sounds like a harmless everyday scene is actually a widespread but often underestimated risk: Many conventional pacifiers are simply too small or poorly shaped. Babies can pull them too far into their mouths, creating a choking hazard. At the same time, large or hard sucking parts put pressure on the sensitive jaw – which can lead to dental misalignments in the long run.

Paul's friend and co-founder Dustin can sing a similar tune. “I have a little sister, and I remember well the constant rashes around her mouth. Back then, no one knew that it was caused by the pacifier,” he says. “Many parents think a pacifier is just a pacifier – but that’s simply not true.”

The hidden dangers of conventional pacifiers

Skin irritations from plastic signs

Behind the plastic shields of pacifiers, moisture can easily accumulate, as these areas are often not well-ventilated. This damp environment provides an ideal breeding ground for bacteria and germs, which can in turn cause skin irritations and red, itchy rashes around the baby's mouth. Such rashes are not only uncomfortable for the child but can also lead to further discomfort and increased scratching. Therefore, it is especially important to pay attention to pacifiers with thoughtful design that allow for better air circulation and thus avoid skin problems.

2. Conventional pacifiers can be swallowed – a often underestimated danger.

Many parents are not aware that conventional pacifiers, despite their seemingly safe shape, can pose a risk. If the pacifier is too small or poorly shaped, it can go too far into the mouth while sucking – in the worst case, all the way to the throat. This can lead to breathing difficulties or even choking hazards. Therefore, the shape of a pacifier plays a crucial role: Only a well-thought-out, safe design prevents the pacifier from being fully drawn into the mouth.

 

3. Unhealthy jaw and dental development

Many conventional pacifiers are not ergonomically shaped and can negatively affect your baby's jaw over time. Dentists warn against pacifiers that are too large.

A long-term study showed that children who use unsuitable pacifiers for an extended period require orthodontic corrections more frequently.

Therefore, it is especially important to pay attention to a narrow and symmetrical suction shaft that is ideally shaped equally on both sides. This prevents the pacifier from applying pressure to specific areas in the oral cavity – significantly reducing the risk of later dental and jaw problems.

 

The idea behind the Nuckly NatureSense and what makes it so special.

When Paul and Dustin recognized these problems, it was clear: This is not how a baby product should look. Both wanted to develop a pacifier that truly does what parents expect – to soothe, protect, and promote health.

 

After countless prototypes, discussions with pediatric dentists, and material tests, the Nuckly NatureSense was finally created – a pacifier that is inspired by nature rather than imitating it.

“We wanted to create something that feels as natural as possible,” Paul explains. “A pacifier that mimics the safety and feel of the breast – without rigid plastic, without pressure, without risk.”

Breast-like shape for a natural sucking experience

The Nuckly NatureSense is designed to closely mimic the natural shape of the mother's breast – both in its curvature and in material feel and flexibility. This gives your baby a familiar, soothing sensation that reminds them of the natural sucking experience at the breast.

The breast-like shape is the most natural orientation for any baby, whether breastfed or not. 

 

2. Skin-like, plastic-free material

While conventional pacifiers contain plastic, the Nuckly NatureSense is made of 100% biocompatible silicone – BPA-free, free from plasticizers and other questionable substances. It comes without a hard plastic shield and rests particularly gently against the baby's face thanks to its skin-friendly, skin-like material. Parents can be assured that their baby only comes into contact with completely safe and naturally appearing materials.

3. Promotes healthy jaw development

The Nuckly NatureSense has been designed to optimally adapt to your baby's natural sucking behavior:

 

Benefits at a glance:

⇛ Narrow, symmetrical shape – always fits correctly        in the mouth 

⇛ Flat, flexible nipple – gentle on the palate       and jaw 

⇛ Supports the baby's natural sucking reflex          

⇛ No pressure on the jaw 

4. Skin-friendly due to optimal air circulation

Through the natural breast shape and the absence of a rigid plastic shield, the Nuckly offers a particularly open and breathable structure. This keeps the sensitive skin around the mouth pleasantly dry – even with prolonged use.

Promotes the jaw muscles – strengthens speech development

The unique, balanced shape of the pacifier encourages your baby to actively keep it in their mouth in a natural way. This specifically trains the jaw and mouth muscles – similar to natural sucking at the breast.

Through this constant balancing, your baby strengthens their jaw muscles. These muscles are crucial for later speech development: Strong oral motor skills support the formation of first sounds and words, ensure a healthy jaw position, and lay the foundation for natural, clear pronunciation.

A pacifier born out of genuine concern

What started as a personal problem has today become a small revolution in the baby world. Parents enthusiastically report fewer skin issues, better sleep, and a more natural sucking behavior from their babies.

Paul smiles as he shares:
“We just wanted to create something that we would feel good about giving to our children. And we did it.”

Finally peaceful nights!   

"Our little Jonas had great trouble falling asleep and often woke up crying in the middle of the night. We tried many pacifiers, but none could really calm him down. Then we tested the Nuckly – and what can I say? Since then, he falls asleep much faster and stays calm longer! I can finally sleep through the night again, and our family life has become so much more relaxed. Absolutely recommendable!"

Perfect for dental development

"My daughter Emma used a cherry-shaped pacifier for a long time until our pediatrician pointed out that this shape can lead to dental misalignments. We then switched to the Nuckly because it supports natural jaw development. I immediately notice the difference: Emma sucks more relaxed, has no more pressure marks on her face, and prefers the pacifier much more than the old models. I am really thrilled!
