Snoring in infancy.

Obstructive sleep apnoea (OSAS) in infants is a risk factor for sudden infant death (SIDS). Snoring in a young child should raise suspicion of OSAS, and according to recent AAP guidelines, evaluation and polysomnographic studies are recommended in selected cases as the diagnostic test of choice. However, infants under 1 y of age are excluded from the guidelines, and interventions to prevent SIDS based on respiratory monitoring remains a matter of controversy. As often happens, the evidence we need most is usually scarce.
