OBJECTIVE Sleep difficulties are highly prevalent and often persistent in young children, but sometimes parents are worried about sleep symptoms that belong to the normative range rather than to actual disturbances. Therefore, the aim of this study was to describe the normative development of sleep at the ages of 3, 6, 8, 12, 18 and 24 months in healthy children. METHODS The present study is based on two birth cohorts that comprise representative samples of families recruited systematically… 
The Effects of Genetic Background for Diurnal Preference on Sleep Development in Early Childhood
TLDR
Genetic liability to diurnal preference for eveningness relates to longer sleep-onset during the first two years of life, and to objectively measured lowered sleep efficiency.
Sleep during infancy, inhibitory control and working memory in toddlers: findings from the FinnBrain cohort study
Background Sleep difficulties are associated with impaired executive functions (EFs) in school-aged children. However, much less is known about how sleep during infancy relates to EF in infants and
Parent-reported early sleep problems and internalising, externalising and dysregulation symptoms in toddlers
TLDR
It is suggested that shorter sleep duration, longer sleep-onset latency and higher waking frequency are related to internalising, externalising and dysregulation symptoms in toddlers, and thus it might be beneficial to provide early interventions for those infants reporting these sleep problems.
The longitudinal associations between temperament and sleep during the first year of life.
TLDR
It was observed that higher infant Negative Affectivity was related to several sleep problems, and that many subscales ofnegative Affectivity and Orienting/Regulation predicted worse sleep and deterioration in sleep problems from six to 12 months.
Association of transportation noise with sleep during the first year of life: A longitudinal study.
TLDR
Sleep in infants during the first year of life was relatively robust against external perturbation by night-time transportation noise, however, particularly in children without siblings increasing night- time transportation noise reduced sleep duration, suggesting that the habitual noise environment may modulate individual susceptibility to adverse effects of noise on sleep.
Possums-based parental education for infant sleep: cued care resulting in sustained breastfeeding
TLDR
The Possums Infant Sleep Program provided equivalent positive results on sleep parameters compared to usual care while advocating a more cued response, and the program was associated with better breastfeeding rates.
A Systematic Review on Attachment and Sleep at Preschool Age
TLDR
The findings were not consistent, with some studies reporting significant associations between attachment security and sleep quality, as well as between attachment insecurity and sleep problems, whereas others did not find significant associations.
A longitudinal study of the links between maternal and infant nocturnal wakefulness.
TLDR
The results suggest that infant and maternal sleep are strongly intertwined, especially during the first 6 months, and the decline in the synchronization between maternal and infant nocturnal wakefulness through infant development may be attributed to the growing ability of infants to self-soothe during the night.
Sleep and obesity in children at different obesity risks : patterns, associations and early intervention
TLDR
Children in the high obesity risk group were more likely to experience unfavourable sleep characteristics than their peers in the low-risk group during the first two years of life, including more transient prolonged sleep onset latency and low sleep efficiency.
Signaled night awakening and its association with social information processing and socio-emotional development across the first two years
TLDR
It is shown that during the first 2 years of life, signaled night awakening is associated with social information processing and socio-emotional behavior.

TLDR
The data provide a context for clinicians to discuss sleep issues with parents and suggest that prevention efforts should focus to the first 3-6 months, since sleep patterns show stability from that time point to 12 months.
Prenatal mood disturbance predicts sleep problems in infancy and toddlerhood.
TLDR
Mood disturbance in pregnancy has persisting effects on sleep problems in the child, a finding that is consistent with experimental animal research and adds to a growing literature showing that maternal prenatal stress, anxiety, and depression may have lasting effects on child development.
Uninterrupted Infant Sleep, Development, and Maternal Mood
TLDR
Considering that high proportions of infants did not sleep through the night and that no associations were found between uninterrupted sleep, mental or psychomotor development, and maternal mood, expectations for early sleep consolidation could be moderated.
The role of parental circadian preference in the onset of sleep difficulties in early childhood.
TLDR
Maternal circadian preference is related to several sleep difficulties in early childhood, and it may be considered a potential risk factor for the onset of early sleeping problems.
Night Awakening in Infancy: Developmental Stability and Longitudinal Associations With Psychomotor Development
TLDR
It is indicated that early onset fragmented sleep did not have a negative effect on psychomotor development within the first 2 years despite the differences in sleep length among infants with and without fragmented sleep.
Predictors of shorter sleep in early childhood
TLDR
Multiple environmental factors were associated with shorter sleep in young children, with several operating predominantly through later bedtime, and an emphasis on the importance of an early and consistent bedtime could help promote healthy sleep and reduce inequalities in child health.
Prevalence and course of sleep problems in childhood.
TLDR
The analysis of self- and parental reports revealed that in general children described significantly more difficulties initiating and maintaining sleep than their parents report.
Maternal and paternal sleep during pregnancy in the Child-sleep birth cohort.
TLDR
The study showed that insomnia and sleep insufficiency are prevalent among women and men during pregnancy and underline the impact of insomnia to both maternal and paternal health during pregnancy as well as to the implementation of effective interventions to prevent negative consequences of sleep disturbances.
Norms and trends of sleep time among US children and adolescents.
TLDR
These estimates are consistent with the amount of sleep recommended for children, and no evidence was found of racial/ethnic differences.
Normal sleep patterns in infants and children: a systematic review of observational studies.
TLDR
Meta-regression showed predominantly Asian countries had significantly shorter sleep (1h less over the 0-12 year range) compared to studies from Caucasian/non-Asian countries.
