The underestimated problem with pacifiers – and why many breastfeeding consultants are rethinking today.

“My heart stopped for a moment.”

When you hear Paul talk about Nuckly today, you immediately notice: This is not a salesperson speaking, but a father. “I remember it clearly,” he recounts, showing an old video of his son. “He suddenly became restless, kept spitting out the pacifier – and nursed differently. That made me suspicious.”

 

Co-founder Dustin also knows the topic from personal experience. “In my family, it was always said: a pacifier is just a pacifier. But no one ever asked if it even fits with breastfeeding.”

Many parents sooner or later hear the term nipple confusion. And indeed, recommendations from breastfeeding organizations show that not every pacifier supports natural sucking behavior. Especially in the first months, an unsuitable design can lead to babies sucking differently than at the breast, becoming more restless, or making breastfeeding more difficult.

 

At the same time, the reality for many parents is different: A baby needs closeness, regulation, and sometimes simply comfort. For Paul, it was clear that it’s not about rejecting pacifiers altogether, but about making them better. When a pacifier is used, it should feel as natural as possible – not as a substitute for the breast, but as a gentle complement.

Nuckly was born from exactly this idea. A pacifier that is oriented towards natural sucking and is consciously designed to be breastfeeding-friendly, to support babies rather than reprogram them. Developed not from a marketing idea, but from a real need.

Because in the end, it’s not about whether you use a pacifier – but which one. 

 

Less confusion. More naturalness. Nuckly.

Problems with classic pacifiers (according to studies & breastfeeding consultation)

Many parents are afraid of the topic of pacifiers – especially due to nipple confusion. And indeed, recommendations from organizations such as the European Institute for Breastfeeding and Lactation (EISL) and La Leche League show:
👉 The wrong pacifier can affect breastfeeding.
👉 But: The correct use – and the right design – makes the difference. content

1. Unnatural sucking shape → Risk of sucking confusion

Many conventional pacifiers have a shape that does not correspond to natural sucking at the breast.

The problem:

  • different sucking pattern than breastfeeding
  • baby has to "relearn"
  • can lead to insecurity at the breast

👉 That’s exactly why lactation consultants recommend:
use pacifiers only when breastfeeding is stable.

2. Pacifiers replace closeness instead of complementing it

Studies show: Sucking is more than just soothing for babies – it also means bonding, closeness, and regulation.

However, if a pacifier is used too early or too often as a quick fix, it can lead to missed hunger cues and disrupt the natural breastfeeding rhythm.

 

3. Design ignores the needs of breastfeeding children

Most pacifiers were not specifically designed for breastfed babies.

Typical problems:

  • too firm / too rigid
  • incorrect shape for breast likeness
  • little adaptation to natural mouth movement

👉 Result: less intuitive sucking

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 has been designed to closely mimic the natural shape of the mother's breast – both in its curvature and in its material feel and flexibility. This creates a familiar, soothing feeling for your baby that strongly resembles natural sucking at the breast.

This breast-like shape is oriented towards what is most intuitive for babies by nature – regardless of whether they are breastfed or not. As Filippi & Verna (2022) show, sucking serves a central function: It helps babies regulate themselves, supports falling asleep, and can reduce stress and even pain.

Nuckly addresses this natural need – not as a replacement for the breast, but as a gentle, breastfeeding-friendly supplement in everyday life.
 

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. More User-Friendly Approach

The breastfeeding-friendly approach of Nuckly clearly aligns with studies and recommendations from breastfeeding organizations: breastfeeding always takes precedence, and a pacifier should not be an alternative, but only a supplement. This is exactly how Nuckly is designed – as support in moments when your baby needs additional regulation, without disrupting the breastfeeding rhythm.

It is consciously stated: as much as necessary, as little as possible.

4. Conscious use instead of a permanent solution

Nuckly is not intended as a "soother," but for a mindful use in everyday life. It comes into play when closeness alone is not enough and your baby needs additional regulation – as a gentle support, not as a permanent solution. This conscious approach also aligns with the recommendations of modern breastfeeding organizations, which advocate for a targeted and needs-oriented use of pacifiers.

5. Promotes natural sucking behavior – for more calm and security

The shape of the Nuckly is consciously oriented towards natural breastfeeding – not only during sucking but also in your baby's behavior. When breastfeeding, babies intuitively reach for the breast, explore and seek support. This need is exactly what Nuckly addresses: Your baby can touch and hold it themselves, which provides additional security and control.

Organizations like the European Institute for Breastfeeding and Lactation (EISL) emphasize how important natural regulation, closeness, and a breastfeeding-friendly approach to pacifiers are. When this need is properly supported, a pacifier can have a calming effect without disturbing breastfeeding.

The result: more security, better acceptance – and less stress in everyday life.

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.”

Breastfeeding finally relaxed again.

“I was really afraid of nipple confusion and was totally unsure whether I should even give a pacifier. Our baby initially drank restlessly at the breast and we were both stressed.

Since we started using Nuckly, it’s completely different. He is accepted much more calmly and it hasn’t disturbed our breastfeeding at all – on the contrary, everything feels more relaxed. You can just tell that it’s more natural.”

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!
