“…While we were unable to directly test the association in this study, nighttime sleep latency, often discussed as bedtime resistance, has been previously related to paternal involvement in bedtime routines (Ragni et al., 2019). This may then speak to paternal involvement in parenting and the home environment, many aspects of which have been linked to differences in infant sleep (review in Dias & Figueiredo, 2019), and should be investigated in future research as an avenue for a potential cascade of biological effects. Moreover, infant sleep problems have been found to correlate with subsequent behavioral problems and maternal depression in the preschool years (Lam et al., 2003), perhaps suggesting that this epigenetic mark may have relevance as an infant biomarker of future problems and burden on caregivers.…”

Adverse childhood experiences (ACEs), or cumulative childhood stress exposures, such as abuse, neglect, and household dysfunction, predict later health problems in both the exposed individuals and their offspring. One potential explanation suggests exposure to early adversity predicts epigenetic modification, especially DNA methylation (DNAm), linked to later health. Stress experienced preconception by mothers may associate with DNAm in the next generation. We hypothesized that fathers’ exposure to ACEs also associates with their offspring DNAm, which, to our knowledge, has not been previously explored. An epigenome‐wide association study (EWAS) of blood DNAm (n = 45) from 3‐month‐old infants was regressed onto fathers’ retrospective ACEs at multiple Cytosine‐phosphate‐Guanosine (CpG) sites to discover associations. This accounted for infants’ sex, age, ethnicity, cell type proportion, and genetic variability. Higher ACE scores associated with methylation values at eight CpGs. Post‐hoc analysis found no contribution of paternal education, income, marital status, and parental postpartum depression, but did with paternal smoking and BMI along with infant sleep latency. These same CpGs also contributed to the association between paternal ACEs and offspring attention problems at 3 years. Collectively, these findings suggested there were biological associations with paternal early life adversity and offspring DNAm in infancy, potentially affecting offspring later childhood outcomes.

“…The present study showed that unsettled sleep in boys is associated with a stronger increase in maternal depression symptoms than unsettled sleep in girls. Previous research has already shown that boys present more sleep difficulties than girls (Dias & Figueiredo, 2020) and that the sleep of boys is more affected by maternal depression symptoms than the sleep of girls (Beeghly et al., 2017; Netsi et al., 2015). A possible explanation for the present study’s results is that in face of the increased sleep difficulties of their sons, mothers of boys may present an increased difficulty in dealing with their infants’ sleep routines, leading to lower maternal self‐efficacy perception and increased postpartum depression symptoms (Falah‐Hassani, Shiri, & Dennis, 2016).…”

Unidirectional and bidirectional links between maternal depression symptoms and infant sleep problems

The links between maternal depression symptoms and infant sleep problems are complex and dynamic. Two models have been tested in the literature to explore these links: the maternal-driven model (Teti & Crosby, 2012) and the infant-driven model (Ystrom, Nilsen, Hysing, Sivertsen, & Ystrom, 2017). The maternal-driven model suggests that maternal depression may predict the emergence of infant sleep problems (Teti & Crosby, 2012), while the infant-driven model suggests that infant sleep problems may predict the emergence of maternal depression symptoms (Ystrom, Nilsen, et al., 2017). According to the transactional model (Sadeh, Tikotzky, & Scher, 2010;Sameroff, 1993), bidirectional links may also occur -maternal depression may influence and concurrently be influenced by infant sleep problems. Although the effects of maternal depression symptoms on infant sleep problems (Bat-Pitault et al., 2017;Martini et al., 2017) and the effects of infant sleep problems on maternal depression symptoms (Wake et al., 2006) have been separately examined in the literature, the bidirectional links were more recently investigated (Galbally,

“…In an Australian longitudinal study of 376 children between two and 24 months of age, 25% of parents reported cry-fuss/sleep problems combined at least once, while they persisted in 6% over at least three-time points [20]. In infancy as well as in toddler and preschool years, sleep problems are associated with short-and long-term impaired regulatory capacity, which is associated with crying [4,15,[21][22][23][24][25][26].…”

A single-arm pilot study: can a parental sleep intervention for sleep-disturbed young children in individual settings improve children’s sleep, crying, eating, and parental distress in mothers and fathers?

Background Early sleep problems co-occur with crying, eating problems, and parental distress. This study investigates the impact of a parent-focused intervention to improve child sleep with the following aims: (1) To assess the impact on child sleep (sleep onset latency, frequency and duration of nighttime awakenings, frequency of bed-sharing, and nighttime food intake, total nighttime sleep duration, and sleep efficiency), child crying (frequency of crying episodes, of unexplained and unsoothable crying and of crying out of defiance), child eating difficulties, and parental distress of mothers and fathers. (2) To assess the maintenance of any changes in these areas longitudinally, at 3-month, 6-month, and 12-month follow-ups. (3) To explore at the within-subjects level, how children’s sleep, crying, eating, and parental distress changed together across all study measurement points. Methods In this single-arm pilot study, the parents of 60 children participated in six individual sessions of a parent-focused multimodal age-adjusted cognitive-behavioral intervention to improve child sleep. Parents of 39 children (46% girls, age in months M = 22.41, SD = 12.43) completed pre- and at least one measure after the intervention. Sleep diary, questionnaire for crying, feeding, sleeping, and parental stress index (short-form) were assessed pre, post, three, six, and 12 months after the intervention. Results Significantly, sleep (decreased sleep onset latency, frequency, duration of nighttime awakenings, bed-sharing, nighttime food intake; increased total nighttime sleep duration, sleep efficiency), crying (reduced frequency of crying episodes, unexplained and unsoothable crying), and parental distress (reduced) changed, which remained partially stable over follow-up. The frequency of crying episodes decreased with fewer nighttime awakenings; morning crying with increased nighttime feeding; unexplained and unsoothable crying with higher sleep efficiency; crying due to defiance with more nighttime awakenings, sleep efficiency, and bed-sharing. Eating problems decreased with shorter night awakenings and time; maternal distress with fewer nighttime awakenings, paternal with less child’s nighttime feeding, unexplained and unsoothable crying, and time. Conclusions A parental sleep intervention for sleep-disturbed young children could be promising to reduce children’s sleep problems, crying, eating problems and parental distress. Future studies should consider more personal contact during the follow-up to reduce the drop-out rate and a randomized-controlled design. Trial registration The study was retrospectively registered at the German Clinical Trials Register (ID: DRKS00028578, registration date: 21.03.2022).
