6 Reasons Why Your Baby's Clicking, Leaking and Trapped Gas are All the Same Problem

Clicking is the first sign the nipple seal is breaking

At first the clicking sounds like a harmless quirk. A tick, a squeak, nothing worth worrying about.

But when it starts happening every feed, you realise that the click is the seal around the nipple constantly breaking and reforming.

Every break interrupts your baby's rhythm. Milk escapes from the corner of their mouth, their grip goes, and they have to find the nipple again.

That's why the clicking always comes with the same three things: a wet chin, frantic sucking, and slipping off the bottle.

So you reposition them. Tilt the bottle. Support their jaw. Start over with new recommendations: a different bottle, a different flow.

Changing the flow swaps one problem for another

A slower nipple stops the milk arriving too fast. But your baby has to suck harder to pull milk through a nipple they were already struggling to hold, so they get frustrated, lose the latch, and pull away before they've finished.

A faster nipple gives them the milk without the work. But now it arrives quicker than they can swallow, so they gulp, cough, leak, and let go to catch their breath.

One stage makes your baby fight to get the milk. The next makes them fight to keep up with it.

Neither one touches the actual problem: the seal. Flow stages adjust the milk pacing when your baby is struggling with the nipple.

Switching brands doesn't change it either. A wider nipple with the same standard-grade material still sits in the mouth the same way, and within a week you're back to choosing between too slow and too fast.

More burping can't fix a feed that keeps putting the air back in

You already burp constantly. Over the shoulder. Over the knee. The whole routine. Then the long wait for a burp that sometimes never comes.

Sometimes it comes up and helps, briefly.

Then the bottle goes back in, the seal breaks in the same place, and the next stretch of clicking and gulping puts the air straight back.

That's how a short bottle becomes an hour of feeding, burping, crying and starting again. And you still can't tell whether the next cry means hunger or trapped air.

Repeat that every few hours, and weeks turn into months of dreading your baby’s hunger cues.

But none of that is an accident. For 30 years the industry has treated the air as the problem, so the innovation went into vents, tubes and valves for the babies that could tolerate awkward nipple shapes.

You're not failing at burping. The air is going in faster than you can get it out.

Why Moka couldn't just be another anti-colic bottle

The big brands all started with the air. The lactation consultants who built Moka started with the seal.

Dozens of nipple shapes, widths, angles and flow variations were tested to find the one babies could hold for a full feed. The result is a wider base and a 15° natural feeding angle in ultrasoft platinum-cured silicone, so your baby draws the nipple deep into the mouth instead of holding a long, straight shape at the front of it.

Five flow stages with laser-cut precision then let you match the pace to how your baby is actually feeding, rather than choosing between frustrated sucking and frantic gulping.

And as milk leaves the bottle, an integrated bottom vent lets air return through the base, so the flow stays steady without a straw or tube running through the feed.

Where milk touches, it touches borosilicate glass and silicone, with a heat-resistant PPSU collar outside the milk path, so daily sterilising doesn't warp the parts that have to stay sealed.

Four open pieces, and nothing hidden to dismantle afterwards.

How over 5000 parents stopped waiting for the next feed to fall apart

It started with parents testing early prototypes near the lab in Zurich. Since then, families who arrived with the same clicking, the same wet chins and the same hour-long burping stretches keep reporting the same changes.

The clicking settled inside the first few feeds. Bottles got finished in one stretch instead of four. Parents stopped moving their baby up and down flow stages hoping the next one would be the one. And babies who had already refused two or three other nipples still took to Moka's wide, softly angled shape.

For over 5000 parents, the real changes showed up after the feed. Fewer stops to burp. Less waiting for air that never comes up. Less guessing whether the next cry means hunger or trapped air. They finally stopped watching the feed and started watching their baby.

The one bottle you can test without another gamble

Waiting doesn't change anything. Tomorrow's feeds run the same as today's: the seal breaks in the same place, the flow stage is still wrong, and you still can't tell whether the next cry means hunger or trapped air.

By now, trying another bottle costs you nothing but another letdown. So the team decided to carry that risk instead of handing it to you.

Every order is protected by a 90-day money-back guarantee. Ninety days covers a full flow-stage change, so you can run Moka through real daytime, nighttime and interrupted feeds before you decide. If the clicking, the gulping and the burping stops haven't changed, the pre-filled return slip is already in the box.

One thing worth knowing before you decide: Moka is made in limited runs because the borosilicate glass and platinum-cured silicone are produced to order, and the team won't substitute cheaper materials to make more of them. When a batch sells through, the next one is six to eight weeks away.

But as of 2026, more than 5,000 families have made the switch, and haven't gone looking for another bottle since.
