“…These findings are consistent with earlier studies using maternal reports of infant sleep (DeLeon & Karraker, 2007). They are also consistent with Volkovich et al (2015), who found that, whereas mothers in co-sleeping arrangements reported higher levels of infant night waking, this link was not borne out by actigraphy, and that it was actually mothers in co-sleeping arrangements, but not infants, whose sleep appeared to be disrupted in co-sleeping arrangements.…”

“…Relevant to this question, however, was whether increases in mother-reported infant night waking would be corroborated by actigraphy, and whether co-sleeping would also be associated with increased wakefulness and sleep fragmentation among parents. Volkovich et al’s (2015) findings suggest that mothers’ reports of infant sleep will not be corroborated by actigraph reports, and that actigraph data would indicate that it will be mothers’, not infants’ night wakefulness, that will be increased in co-sleeping arrangements. We will determine if these patterns are replicated in the present study, and whether paternal sleep, which was not examined by Volkovich et al, is linked with sleep arrangements.…”

The present longitudinal study addressed the ongoing debate regarding the benefits and risks of infant-parent co-sleeping by examining associations between sleep arrangement patterns across the first year of life and infant and parent sleep, marital and family functioning, and quality of mothers’ behavior with infants at bedtime. Patterns of infant sleep arrangements across the infants’ first year were derived from information obtained from 139 families at 1, 3, 6, 9, and 12 months of infant age in a U.S., central Pennsylvanian sample. Linkages between these patterns and parent-infant sleep, marital and coparenting stress, and maternal behavior at bedtime (from video-recordings) were assessed. Compared to families whose infants were solitary sleepers by 6 months, persistent co-sleeping was associated with sleep disruption in mothers but not in infants, although mothers in persistent co-sleeping arrangements reported that their infants had more frequent night awakenings. Persistent co-sleeping was also associated with mother reports of marital and coparenting distress, and lower maternal emotional availability with infants at bedtime (from home observations). Persistent co-sleeping appeared to be a marker of, though not necessarily a cause of, heightened family stress, although the present design did not enable strong tests of causal processes, and results may be particular to cultures that are not supportive of co-sleeping. Findings are discussed in terms of cultural contexts of infant sleep and the need for further investigations into the role of the health of the family system in influencing how parents structure infant sleep.

“…It also conflicts with other data that room-sharing is associated with more sleep disruption for mothers. 24,38 Our data showing shorter night sleep and shorter sleep bouts for infants who are room-sharing has potentially important consequences.…”

“…21 The 1-year recommendation has questionable congruence with the epidemiology of SIDS (as risk is far lower after 6 months), and it runs counter to the common clinical advice parents receive. Based on evidence of improved infant sleep, [22][23][24] clinicians may encourage parents to establish independent sleep environments (ie, in a separate room from parents) during the middle of the first year to promote healthy and sustainable sleep patterns before the typical onset of separation anxiety later in the first year. 25 Therefore, in this secondary data analysis, we sought to evaluate the associations between room-sharing on a separate sleep surface and sleep-related outcomes from the cohort participating in the Intervention Nurses Start Infants Growing on Healthy Trajectories (INSIGHT) study.…”

The American Academy of Pediatrics recommends infant-parent room-sharing until age 1. We assessed the association between room-sharing and sleep outcomes. METHODS:The Intervention Nurses Start Infants Growing on Healthy Trajectories study is an obesity prevention trial comparing a responsive parenting intervention with a safety control among primiparous mother-infant dyads. Mothers completed the Brief Infant Sleep Questionnaire at 4, 9, 12, and 30 months. Reported sleep duration and overnight behaviors, adjusted for intervention group, were compared among early independent sleepers (own room <4 months), later independent sleepers (own room between 4 and 9 months), and room-sharers at 9 months. RESULTS:At 4 months, reported overnight sleep duration was similar between groups, but compared with room-sharers, early independent sleepers had better sleep consolidation (longest stretch: 46 more minutes, P = .02). At 9 months, early independent sleepers slept 40 more minutes nightly than room-sharers and 26 more minutes than later independent sleepers (P = .008). The longest stretch for early independent sleepers was 100 and 45 minutes more than room-sharers and later independent sleepers, respectively (P = .01). At 30 months, infants sleeping independently by 9 months slept >45 more minutes nightly than those room-sharing at 9 months (P = .004). Room-sharers had 4 times the odds of transitioning to bed-sharing overnight at both 4 and 9 months (P < .01 for both). CONCLUSIONS:Room-sharing at ages 4 and 9 months is associated with less nighttime sleep in both the short and long-term, reduced sleep consolidation, and unsafe sleep practices previously associated with sleep-related death.

“…Finally, it is important to keep in mind that maternal sleep is both highly variable between postpartum women and is not stagnant within women across the postpartum period [89,90]. As such, our use of averages to model the number and duration of awakenings cannot be broadly applied to all postpartum sleep experiences.…”

Study Objectives The maternal postpartum period is characterized by sleep fragmentation, which is associated with daytime impairment, mental health disturbances, and changes in melatonin patterns. In addition to sleep fragmentation, women undergo a complex set of physiological and environmental changes upon entering the postpartum period, confounding our understanding of effects of postpartum sleep disturbance. The primary study aim was to understand the basic impact of a single night of postpartum-like sleep fragmentation on sleep architecture, nocturnal melatonin levels, mood, daytime sleepiness, and neurobehavioral performance. Measurements and Results For one week prior to entry into the laboratory, eleven healthy nulliparous women kept a stable sleep-wake schedule (verified via actigraphy). Participants contributed three consecutive nights of laboratory overnight polysomnography: (1) a habituation/sleep disorder screening night; (2) a baseline night; and (3) a sleep fragmentation night, when participants were awakened three times for ~30 min each. Self-reported sleep quality and mood (Profile of Mood States Survey) both decreased significantly after sleep fragmentation compared to baseline measurements. Unexpectedly, daytime sleepiness (Multiple Sleep Latency Test) decreased significantly after sleep fragmentation. Experimental fragmentation had no significant effect on time spent in nocturnal sleep stages, urinary 6-sulphatoxymelatonin concentration, or psychomotor vigilance test performance. Participants continued to provide actigraphy data, and daily PVTs and self-reported sleep quality assessments at home for one week following sleep fragmentation; these assessments did not differ from baseline values. Conclusions While there were no changes in measured physiological components of a single night of postpartum-like experimental sleep fragmentation, there were decreases in self-reported measures of mood and sleep quality. Future research should examine the effects of multiple nights of modeling postpartum-like sleep fragmentation on objective measures of sleep and daytime functioning.
