>>3302370The most important part is to breathe through his nose with a correct oral posture (tongue on the roof of the mouth), not only while awake, but also while sleeping. Male sure his bed, matress, and room is kept cas clean and clear of clutter as possible. No animals or plush toys. Nothing that may acumulate dust or mold.

>The photograph on the left above shows a boy at the age of ten. He breathes through his nose and has a well-developed face. Everything is proportional and the boy has well-defined eyes, cheekbones, lips and chin. When he was 14, he got a gerbil and developed an allergy that left him with a stuffy nose, which caused him to start breathing through his mouth.>The photos in the middle and on the right show the same boy at the age of 17. Breathing through his mouth caused his face to grow downward instead of forward, making his face long and narrow. His nose looks larger and his chin is narrow because his upper and lower jaws did not grow forward. Facial changes caused by mouth breathing lead to constricted breathing passages that in turn may lead to snoring and sleep apnea.Then, as he starts developing his first teeth, give him some hard food to chew. Chewing AND swallowing food should also be done with a correct posture.
