Insights
Infants frequently use various sleep aids, like thumbs or soft objects, and often switch between them. A novel maternal odor sleep aid was explored for infant self-soothing during nighttime awakenings.
Area of Science:
- Developmental Psychology
- Infant Sleep Behavior
Background:
- Infants often use objects for self-soothing during sleep.
- Understanding infant sleep aid preferences is crucial for developing effective sleep interventions.
Purpose of the Study:
- To investigate infant sleep aid usage across different age groups (3-12 months).
- To examine the utilization of a novel maternal odor-infused sleep aid.
- To assess the interchangeability of sleep aid preferences in infants.
Main Methods:
- Longitudinal study over 3 months with nighttime video recordings.
- Observation of sleep onset and nighttime awakening behaviors.
- Analysis of sleep aid use in 4 infant age groups.
Main Results:
- Infants demonstrated age-dependent preferences for sleep aids (e.g., thumbs vs. soft objects).
- 6-month-olds showed the highest usage of the novel maternal odor sleep aid.
- Nearly all infants used some form of object, and patterns of use evolved over time.
Conclusions:
- Infants in their first year commonly use multiple sleep aids interchangeably.
- Sleep aid preference is dynamic, not fixed to a single object.
- Findings support the frequent and flexible use of sleep aids by infants.
Objective:
In an attempt to foster self-soothing during the night, a novel sleep aid infused with maternal odor was introduced to 4 groups of infants ranging in age from 3 to 12 months. Infants' use of parent-provided sleep aids also was examined.
Methodology:
Nighttime sleep and waking behaviors were videotaped for 2 consecutive nights on 3 occasions over a 3-month interval. Using all-night video recording, the study examined the infant's use of a novel sleep aid and parent-provided sleep aids during sleep onset and after nighttime awakenings.
Results:
Results indicated that infants of different ages differed in the types of sleep aids used when falling asleep either at the beginning of the night or after awakenings in the middle of the night. More 3-month-olds used their thumbs/fingers/hands, whereas more 6-month-olds used soft objects. The 6-month-olds were most likely to use the novel sleep aid. Almost all of the infants at all 4 ages used some type of object during the night. Intra-individual analyses showed that infants tended to change their pattern of sleep aid use over the 3-month study period.
Conclusions:
The data provide evidence that infants during the first year of life use sleep aids frequently and interchangeably rather than a specific favorite object.

Sedatives and Hypnotics: Overview
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...

Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
