Buteyko meets Dr Mew by Patrick McKeown is a 3 in 1 to cover all ages. There is a children's self help story book, teenagers' self help comic and parents section with medical references. Invaluable guidance is provided for correct facial development, nasal breathing and straight teeth. Without doubt, youth who mouth breathe are at a distinct disadvantage for facial appearance, sleep quality, and academic performance. This information is essential and should be taught in all schools as a basic life skill.
