The American Academy of Pediatrics, or AAP, recommends that babies always be placed on their backs to sleep, even for just a nap.
I think this is worst advice ever. I don’t find convincing the evidence that this reduces death of infants. I am convinced instead that it leads to widespread sleep problems among babies at least until age four, it slows their motor development and probably their cognitive development, and leads to many children wearing helmets to reshape their heads.. A friend of mine quoted a pediatric physical therapist as saying, “The back-sleepers keep me in business.”
Of course, it is not typically rational for a non-expert to challenge orthodoxy. So call me crazy.
