This book is a practical, comprehensive look at safe sleep for infants, including infants with co-occurring medical conditions. It offers guidance for clinicians who are counseling parents and other infant caretakers, and discusses common barriers to adherence and approaches that are evidence-based or use behavior change theory. Chapters focus on pathophysiology, important aspects of the sleep environment, and infant product safety. There is a closing chapter on grief and counselling families after a loss. Chapters open with a clinical vignette and close with a discussion of frequently encountered questions, and clinical pearls and pitfalls. All chapters have been fully revised to include the most current research. Three new chapters have been added on the genetics of sudden and unexpected death, infant biomechanics and implications for safe sleep, and firm and flat sleep surfaces. Infant Safe Sleep, 2e,is a valuable resource for pediatricians, other clinicians, healthcare and public health professionals, and others caring for children.
