 Behavioral Insomnia of Childhood BIC is among the most prevalent problem presented to pediatricians with a reported occurrence of approximately 30 worldwide.The most widely applied treatment strategies for BIC in infants comprise behavioral procedures such as unmodified extinction; graduated extinction ignoring the infant cries with minimal checks, or camping out. Unfortunately, breastfeeding is usually considered as an undesirable sleep association in these strategies. Moreover, less is known regarding the effects of these interventions on breastfeeding outcomes. The cued care is defined as a pattern of care characterized by sensible caregiver responsiveness, which meets the need underlying the infants cues in a flexible manner. In this context, POSSUMS has been developed as a cued care sleep intervention, which is quite different from the conventional sleep training techniques. In the current study, investigators hypothesized that mothers receiving the cued care sleep intervention would report less sleep problems in their infants. Secondary outcomes included improvement in maternal mood and maintenance of the breastfeeding during the observation period.
