Sleep training (sometimes known as sleep coaching) is a set of parental (or caregiver) intervention techniques with the end goal of increasing nightly sleep in infants and young children, addressing “sleep concerns”, and decreasing nightime signalling. Although the diagnostic criteria for sleep issues in infants is rare and limited, sleep training is usually approached by parent(s) or caregivers self indentifying supposed sleep issues.The idea of early independence and sleep training in babies was promoted by Dr. Luther Emmett who published The Care and Feeding of Children in 1894. This is widely believed to be the basis from which, modern sleep training has evolved.
