Does your baby refuse every pacifier?

It's not stubbornness. It's the shape.

Babies know the difference between a hard plastic nipple and the soft, wide shape they know from nursing. Spitting it out is a reflex, not a choice.

Gets spat out

Narrow, firm nipple. Pushes the tongue back and feels foreign in the mouth. Most babies push it out within seconds.

How it works
The solution: a breast-like shape

Feels like nursing. That's the whole trick.

Nuckly was developed over two years with midwives, doctors and hundreds of families. The shape follows the anatomy of the breast, and your baby's reflexes do the rest.

1
Lips roll outwardThe wide, soft base lets the lips flange out naturally, exactly like at the breast. No pursing, no strain.
2
A gentle vacuum formsWith the tongue in front, sucking creates the same soft vacuum as breastfeeding. Sucking becomes effortless.
3
The calming reflex kicks inEffortless sucking triggers the relaxation reflex. Your baby settles, and so do you.

"Worked on the very first try."

Tried three pacifiers, he spat them all out. With Nuckly it worked on the very first try. It just feels different, softer, more natural. He's been sleeping better ever since, and so have I.

Questions? Answered.

Everything parents ask us before their first Nuckly.

Choose your set
What if my baby doesn't accept Nuckly?

Most babies accept Nuckly within the first few tries because the shape feels like the breast. Offer it in a calm moment, for example after feeding, and gently stroke the cheek so the sucking reflex kicks in. If it still doesn't work out, our support team is happy to help with tips, and returns are easy.

Can I use Nuckly while breastfeeding?

Yes. Nuckly was developed together with midwives specifically to combine with breastfeeding. The wide, soft nipple encourages the same natural sucking pattern as nursing, which helps avoid nipple confusion.

Which age is Nuckly suitable for?

Nuckly is designed for babies from birth. The one-size shape adapts naturally to the baby's mouth. As with any pacifier, please check it regularly and replace it every 1 to 2 months.

What is Nuckly made of?

100% medical-grade silicone, free from BPA, PVC and phthalates. It's a single piece with no seams or gaps, so nothing can get stuck inside and there's nothing to take apart.

How do I clean and sterilize it?

Boil it for 5 minutes before first use, then rinse with warm water day to day and sterilize regularly by boiling or in a sterilizer. Nuckly is fully transparent, so you can see it's clean. Please keep it out of the microwave and dishwasher, high heat can damage the material.

What exactly is in the Starter Set?

Two Nuckly pacifiers: one for home, one for the bag. Both in medical-grade silicone, suitable from birth. Everything you need from day one.

Do you ship to my country, and how fast?

We ship internationally. You'll receive a tracking link as soon as your order leaves the warehouse. Not happy? Easy returns, no questions asked.
