My son 3 years breaths bad he gaps for air when he sleeps. he doesn't eat well. he snores while he sleeps. it's bothering me that he struggles to breath when he sleeps. his breath smells even though we brush it with baby toothpaste?

It's movie time: If problem is sudden and new, the doctor or ER can help today. Otherwise, parents can make a movie of his snoring to show what's happening. Show the face, chest, and tummy at the same time, so Dr. can see how things moves during breathing. A minute into the movie, open his mouth to show how the breathing changes; and then a minute later, close the mouth to show how the breathing changes again.

Airway: Son may have an airway insufficiency, periodontal disease, cavities, enlarged tonsils/adenoids, etc. Imperative that he see a specialist Pediatric Dental Specialist, a Pedodontist, immediately. Pedodontist may also want to consult with a specialist Pulmonolgist because of your son's signs of sleep apnea. And start flossing your son's teeth daily, t'paste/t'brush alone only gets teeth 65% clean.
