If you’re here because you searched “triangle test pacifier,” welcome—you’re not crazy, you’re just a smart, research-driven parent. And honestly? That’s my favorite kind.

Let’s talk about what the triangle test actually is, why so many parents are suddenly searching for it, and how it connects to pacifiers (yes, including yours truly at Soothe Beginnings).

First: What Is the Triangle Test?

Created by expert Kaylee Rabaja, the triangle test is a simple way to check whether a bottle nipple encourages a proper latch—similar to breastfeeding.

It works like this:

👆 Hold the nipple and form a triangle with your index fingers across the tip.
✅ If there’s little to no space between the nipple and your fingers, that shape supports a wide, deep latch.
💬 This tells you the nipple encourages your baby to use their tongue and jaw effectively.

It’s brilliant in its simplicity it makes so much sense. A shape that mimics breastfeeding mechanics is better for milk transfer, reduces air intake, and helps babies feed more efficiently.

But Here’s the Twist: This Applies to Pacifiers, Too

Pacifiers aren’t just comfort tools, they’re oral tools.

So if you're looking for one that won’t interfere with breastfeeding, doesn’t confuse baby, and actually supports oral development, you should be triangle testing your pacifier nipples, too.

And guess what?

✅ Our Standard and Nursing Shapes Pass

Kaylee herself tested our pacifier nipples on video, and both our Standard and Nursing shapes passed the triangle test.

That means they promote a wide latch and proper muscle engagement, even when baby is soothing, not feeding.

💡 Why this matters:

• Supports oral development

• Reduces the risk of poor latch habits

• Helps preserve the breast-bottle-pacifier balance

• Comforts without compromise

Skip the Guessing. Start with the Right Shapes.

Our Pacifier Starter Kit was made for this exact moment.

✔️ Three nipple shapes (Orthodontic, Standard, and Nursing)
✔️ One customizable, dishwasher-safe shield

For the Parents Doing the Deep Research

You’re not just buying a pacifier. You’re looking for:
