Newborn breathing with mouth open

When it comes to the sleep habits of infants, you might find yourself coming across some strange explanations. After all, it’s a time when almost everything your baby does is weird. But why does newborns sleep with mouth open while sleeping? Well, there’s an explanation for it. This article covers facts and myths on newborn breathing with mouth open.

If you have ever observed a sleeping baby, especially one who is nearing six months of age, you may have noticed that they tend to breathe through their open mouth as opposed to their nose. This happens on an almost constant basis and there isn’t anything to worry about. It seems bizarre and unnatural, but this can also happen to adults who are experiencing extreme stress and anxiety. Babies tend to breathe through their mouth when they aren’t getting enough air through their nose due to congestion or blockage in the nasal passages from mucus buildup.

Babies breathe better through their mouth

Babies tend to breathe with their mouth open because their nose isn’t fully developed. The main reason for a newborn breathing with mouth open is that their nasal passages aren’t fully formed yet and are quite narrow to breathe enough oxygen, which can make breathing through the nose difficult. Babies can also have a lot of nasal mucus and have trouble clearing it out. In some situation, a bulb syringe is used to clear child’s nose.

Due to these factors, babies are forced to breathe through their mouths. This can be rather uncomfortable and make it almost impossible to rest peacefully. They tend to rest their tongue against the roof of their mouth, which keeps the airway open.

Babies who breathe through their mouths may also have a red or blotchy face.
