What's happening to your child's face while they sleep
What's happening to your child's face while they sleep
The way your child breathes at night helps shape the face they'll grow into.
There's a name for what goes wrong. It's called long face syndrome, and paediatric airway dentists have studied it for twenty years. Most parents have never heard of it, because a routine check-up doesn't look for it.
When a child sleeps with their mouth open on a pillow that doesn't support them, the tongue falls back, the jaw drifts backwards and the upper palate narrows. Over the years, the face starts to grow downwards instead of forwards. Most of that shaping happens before the age of nine, so those early years are the ones that count.
Left alone, it usually shows up later at the orthodontist: crowded teeth, a weaker chin, dark circles, and braces that run from £3,000 to £8,000, or jaw surgery past £20,000.
Nubo works on the cause rather than the symptoms. Its three zones hold the head, neck and jaw in the right alignment all night, from the very first use.
Most parents notice the change quickly. The mouth breathing usually settles within a couple of weeks, with lips sealed, nasal breathing back, and no more dry mouths or damp pillowcases in the morning. The snoring tends to go within the first week, including the soft kind ENT specialists treat as an early warning sign. With the head held in the right position and the mouth closed through the years that matter most, the face gets the chance to grow forwards, towards a firmer jawline and a stronger chin, naturally, rather than being fixed with surgery later.
That's what £39 buys you now, against a problem that costs thousands and only gets harder to fix with every year that passes.
My child is right between two sizes. Which one should I choose?
My child is right between two sizes. Which one should I choose?
If your child's age falls on the overlap between two sizes, go for the larger one. The pillow is made to support healthy alignment as they grow, so the bigger size gives a little more room and a longer window of use.

What it's made of
- Soft, cool fabric. Silky lyocell on one side, breathable mesh on the other, so they never wake up hot and sweaty.
- A core that never goes flat. Flexible tubes hold the exact height for their age, year after year.
- A light, fresh fill. Antibacterial and hypoallergenic, so the pillow stays clean.
- Safe against their skin. Independently lab-tested, with no harsh chemicals.
Three sizes, matched to your child's age (L × W × H)
- 2 to 3 years — 50 × 30 × 4 cm
- 3 to 8 years — 50 × 30 × 6 cm
- 8 to 18 years — 50 × 30 × 9 cm
Independently lab-tested for safe skin contact
Independently lab-tested for safe skin contact
Your child spends up to ten hours a night with their face pressed against this pillow. That is why we had the pillow's surface fabric put through independent laboratory testing, held to the strictest class of safety requirements for infant textiles. Here is exactly what came back.
- No formaldehyde detected. None found, below the strictest infant-textile limit.
- No banned azo dyes. A full 24-substance screen for carcinogenic dyes came back completely clear.
- Skin-friendly pH. Measured within the range recommended for direct, all-night skin contact.
- Saliva-safe. Top colourfastness grade, so nothing leaches when your child drools, mouths, or chews the fabric.
- Sweat and wash resistant. Highest colourfastness grade, with no fading and no dye bleeding.
- Odour-free. No chemical smell, straight out of the wrap.
- Breathable by design. Silky lyocell on one side, a breathable bird's-eye mesh on the other: it wicks moisture and lets heat escape, keeping the surface cool and dry.

Cotton Pillowcase
Engineered with paediatric airway dentists
Start putting it right tonight
Paediatric airway dentists keep warning parents about the same quiet problem. A child who snores and breathes through their mouth isn't simply sleeping badly. Over time, the jaw, palate and face can grow in the wrong direction, and the window to guide it doesn't stay open forever.
Nubo, the Kids' Posture Pillow, is designed to support the head, jaw and airway in the right position through the night, encouraging nasal breathing and healthier facial development while it still counts.
It's more than a pillow. It's nightly support for your child's airway during the years that shape their face.
Why 30,000+ parents switched to Nubo
Most kids' pillows are just smaller versions of adult ones: too high, too soft, the wrong shape for a growing child. Their head tips back, their mouth falls open and they breathe through it all night. Nubo is built around a child's head, neck and shoulders, so they stay aligned, keep their mouth closed and sleep deeper.
Parents saw it. Kids felt it.
Quieter nights, closed mouths, easier mornings. We asked Nubo parents what changed after the switch, and here's what they told us.

How fast will I see the mouth breathing stop?
How fast will I see the mouth breathing stop?
Most parents notice the snoring settle and fewer mouth-open wake-ups within the first week. By around night 14, the lips stay sealed through the night. The bigger changes, a clearer jawline, fading dark circles and a shift in the way the face is growing, tend to show around day 21 to 30. Use it every night, as the effect builds over time.
What age range is Nubo for?
What age range is Nubo for?
Nubo comes in three sizes covering ages 2 to 18, so there's a proper fit at every stage. It matters most in the early years, though. The palate does most of its growing before the age of nine, while the jaw is still forming and mouth-breathing habits are still easy to turn around. After that, changes are harder to make and usually mean expanders, braces or surgery. Those early years are the ones Nubo is really built for.
Is it safe? What's inside?
Is it safe? What's inside?
Yes. On the outside, it's soft, breathable lyocell on one side and a 3D bird's-eye mesh on the other. Inside, a core of flexible TPE tubes holds the height, wrapped in a light EPE and Invista fibre fill that's antibacterial. Everything is hypoallergenic and OEKO-TEX certified, with no formaldehyde, no heavy metals and no BPA. It's dust-mite resistant and made to strict safety standards for children.
Will my child actually use it?
Will my child actually use it?
Yes. The ergonomic shape feels supportive rather than strange, and most children settle into it within a night or two. Plenty of parents tell us their child won't sleep without it after the first week. The three zones cradle the head naturally, so there's no special position to get right and no battle at bedtime.
Does it work if my child already breathes through their mouth?
Does it work if my child already breathes through their mouth?
Yes, that's exactly who it's for. The three-zone shape stops the head tilting back, which is what makes the mouth fall open in the first place. Within one to two weeks, the lips tend to seal on their own, nasal breathing returns, and things slowly start to turn around. The longer your child has breathed through their mouth, the more noticeable the change.
What if it doesn't work for my child?
