REST Routine was based on a theoretical model that conceptualizes infant colic using a developmental psychobiological perspective. Colic, also referred to as irritable infant syndrome, is viewed as a delay or disturbance in the infant’s sleep-wake cycling. Colicky or irritable infants have a disorganized or undeveloped sleep-wake cycle that leads to excessive crying and difficulty initiating sleep. This behavior instability may be exacerbated by parental inconsistency and environmental disruptions.
From this framework, irritable infants are viewed as sensitive and more easily over-stimulated by busy chaotic environments. As they become overwhelmed and fatigued, they cannot self-soothe or reduce their arousal level sufficiently to fall asleep. Parents may actually reinforce the irritable behavior pattern by using inconsistent strategies that are not compatible with the infant’s unclear signals and erratic cues. To address these issues, REST Routine provided support for the parents and modification of the infant’s environmental care routines.
REST Routine was a home-based intervention model with activities for infants and parents. For infants, nurses developed specific recommendations and care plans based on four guiding principles:
- Regulation, the support required to assist infants in regulating their state behavior and to protect them from becoming overstimulated and exhausted during the first few months of life
- Entrainment, whereby the infant’s basic sleep-wake cycles were synchronized with relevant aspects of the environment
- Structure, or repetition, to create a predictable and recurrent pattern of events for infants who were not intrinsically well organized
- Touch, which included various infant holds and positions
Similarly, four concepts guided nurses in working with parents:
- Reassurance focused on the infant’s health and the parent’s competence
- Empathy from nurses, who listened and acknowledged the challenge of parenting high-need and high-maintenance infants
- Support from nurses, who served as an advocate and resource for parents in obtaining assistance and creating a support network
- Time-out legitimized the primary caregivers’ critical need to take care of themselves. A specific period of time-out from parenting (at least one hour) was scheduled into each day
During the last home visit, nurses assessed the need and options for ongoing support and intervention. Home-visiting nurses also could conduct follow-up phone calls to check in with families.
REST Routine targeted families with healthy, full-term infants who had excessive and unexplained irritability or colic.
