 Behavioral Insomnia of Childhood BIC is among the most prevalent problem presented to pediatricians with a reported occurrence of approximately 30 worldwide.Like all the other behavioral problems, sleep problem is defined by the the parents, and influenced by parental psychopathology, parenting styles, family dynamics, culturally-based differences in values, socio-economic factors, temperament, developmental stage and medical condition of the child. Moreover, there is also data suggesting an association of depressed mood among mothers to infants with BIC. 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. The primary outcomes of these interventions include enabling infants to learn to self soothe to sleep, having less fragmented night-time sleep and longer night-time sleep periods. 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. Within the infant sleep research field, not breastfed but the formula fed baby is usually considered as the biological norm. However, since nursing influences both the maternal and infant sleep architecture, the outcomes of those behavioral interventions can not be accurately evaluated without considering the breastfeeding.
