Proper tongue resting posture matters more than most parents are ever told!
When your baby is at rest or asleep, the tongue should gently rest up on the roof of the mouth (the palate), with lips closed and the jaw relaxed. The tip of the tongue naturally sits just behind the top front teeth, often called “the spot”.
This isn’t just about the mouth though…It actually all starts with the tongue. 👅
Your baby’s tongue plays a crucial role in feeding, swallowing, breathing, facial development and sleep. Where the tongue rests helps support nasal breathing, keeps the airway more open, and allows breathing to stay quiet and efficient during sleep.
When your baby’s tongue sits low on the floor of the mouth, whether due to oral dysfunction, muscle fatigue or a tongue tie, breathing can become noisy, even when the lips are closed. This is why some babies snore, sound congested, or breathe heavily during sleep despite appearing to have their mouth shut.
A low tongue posture can also influence palate shape over time. The tongue acts like a natural palate expander in little babies and children. When it rests low, the palate may become higher or narrower, which can further affect airway space, breathing, digestion, feeding efficiency and sleep quality.
The tongue is also closely linked to the nervous system. When the tongue rests up against the palate it helps stimulate the vagus nerve, which supports the “rest and digest” system. This plays a huge role in calming your baby and supporting the release of serotonin and melatonin, both important for deep, restorative sleep!
When your baby cannot maintain this tongue posture on their own, they may seek extra sucking for comfort, feed more frequently overnight, or rely on a dummy (or thumb). Over time, this can look like a sleep issue, but the root cause may actually be your baby’s tongue!
This is why tongue position matters!
If your baby snores, struggles with feeding, or seems unsettled despite being tired, their oral function and tongue posture may be worth a closer look. We can help you!
