Sleep Training for Infants and Young Children

Core Components of the Bedtime Routine

A warm bath 90 minutes before bedtime facilitates the natural drop in core body temperature that promotes sleep, according to the Journal of the American Geriatrics Society 1
Calming activities such as gentle massage, quiet reading, or lullabies performed in the same sequence each night are beneficial for sleep, although the specific citation for this is ignored, a consistent bedtime and wake time maintained 7 days per week is recommended by Current Obesity Reports 2 and Journal of the American Geriatrics Society 1
A consistent bedtime and wake time maintained 7 days per week, regardless of how much sleep was obtained the previous night, is crucial for establishing a healthy sleep schedule, as suggested by Current Obesity Reports 2 and Journal of the American Geriatrics Society 1

Use the bedroom only for sleep (and feeding in infancy)—no play, television, or stimulating activities in the sleep space, as recommended by the American Academy of Sleep Medicine 3 and Journal of the American Geriatrics Society 1
Put the infant to bed drowsy but awake rather than fully asleep, to establish independent sleep initiation skills, according to the American Academy of Sleep Medicine 3
Maintain a 12-hour light/12-hour dark schedule to support circadian rhythm development, with exposure to bright light during the day and darkness at night, as suggested by Current Obesity Reports 2
Establish consistent feeding times that align with the sleep schedule, as feeding timing influences circadian synchronization in infants, according to Current Obesity Reports 2

Infants (4-11 months) should aim for 12-15 hours of sleep, with progressive consolidation toward longer nighttime sleep (10-12 hours) and shorter daytime naps (3-4 hours), as recommended by Current Obesity Reports 2

Avoid using antihistamines like diphenhydramine for infant sleep problems—they lack efficacy data, cause problematic side effects, and tolerance develops rapidly, although this is based on a citation from Praxis Medical Insights 4, it is worth noting
Avoid inconsistent schedules and on-demand nighttime feeding beyond early infancy, as these delay circadian rhythm organization, according to Current Obesity Reports 2
Do not allow screen time or stimulating activities near bedtime, as these interfere with sleep onset, as suggested by Journal of the American Geriatrics Society 1

Starting too late—begin establishing routines in the first weeks of life rather than waiting until sleep problems develop, according to Current Obesity Reports 2
Ignoring environmental factors—ensure the sleep space is dark, quiet, cool, and free from screens and stimulating toys, as recommended by Journal of the American Geriatrics Society 1

Formal sleep restriction therapy (limiting time in bed to match actual sleep time) under guidance may be considered if a consistent bedtime routine does not produce adequate improvement, as suggested by the American Academy of Sleep Medicine 3
